Six improvement trends of household plastics

can be tested through tensile test

as household plastics, its indicators are stricter than ordinary plastics. At present, there are six trends in household plastics in China. In this trend, major manufacturers are seeking solutions. At present, there are six trends of modified plastics for household appliances. Mainly: more bright appearance color environmental protection; Safety module indicators continue to improve; Light weight transition from automobile to household appliance; The health module is initially reflected; Low cost is the eternal theme; Energy saving low carbon materials

1. Appearance color module solution

technology and fashion personalized color appliances have become the inevitable trend of current development. The main solutions are:

1) use bright, high gloss, scratch resistant materials, etc

the materials are more colorful, such as bright black, purple red, light green, bright red, sea blue, etc

2) spray free series - pearlescent, metallic, etc

can make plastic products achieve the same effect as silver white, earthy gold, silver gray and other metals without spraying and electroplating

3) other special effects - marble, crystal flow color marble, crystal flow color

make the color of plastic products reach the same effect as large

marble or granite

2. Safety material module solution

safety appliances have become the basic elements of current development. Safety appliances have become the basic elements of current development

1) high flame retardant materials and halogen-free low smoke materials

such as refrigerator, air conditioner, washing machine motor box and other internal or external parts adopt low smoke bromine PHOSPHORUS SYNERGISTIC high flame retardant pp/abs/ps or low smoke halogen-free flame retardant pp/abs/ps/pbt and other materials to meet the requirements of 1.5mm5va, gwit850 ℃

2) high performance materials

permanent antistatic color pp/abs/ps are used in refrigerators, air conditioners and washing machine shells; Abs/pp/pa/pbt with high flame retardant and high leakage trace are applied to electric control components; Conductive pp/abs/ps/pbt shall be used for internal functional parts. Meet the requirements of white permanent antistatic 109, high CTI value (600V), etc

3. Lightweight material module solution

it is an inevitable trend for lightweight products to extend from automobiles to household appliances

1) glass is replaced by plastic, high transparent and high rigid materials

high transparent pp/abs/pmma/petg/pes/psf and other components are used on the observation window to meet the requirements of food hygiene or scratch resistance/strength on the basis of transparency

2) steel is replaced by plastic, and rigid strength and high hard dimensional stability materials

high strength materials with high glass fiber content (50%) and long glass fiber reinforced materials (lft-pp/pa) are used in refrigerator, air conditioner, washing machine and other technical structural parts; Glass fiber reinforced special engineering materials (pps/pei) are applied to wear-resistant parts. These materials meet the requirements of high strength, high wear resistance, boiling resistance and temperature resistance of structural members; In addition, under the same strength, the microcellular foaming material can significantly reduce the weight of household appliance plastics, and has no warpage and shrinkage marks, which has higher strength and processability

4. The health material module solution

health concept has become a fashion in the development of home appliances

1) antibacterial/mildew resistant material

add inorganic environmental protection composite antibacterial masterbatch or organic macromolecular antibacterial material. To meet the antibacterial requirements, no secondary pollution (AG, as ions) can be introduced. It can be applied to internal or external parts such as refrigerators, air conditioners, washing machines, etc

2) non toxic environmental protection materials

C volatile materials (pp/ps/abs, etc.) are made by using low VO sputtering equipment to stack positive electrodes, solid electrolytes and negative electrodes, which are applied to internal and external components of home appliances; Non plasticizer elastomer material (tpe/tpv) is used for door seals and gaskets. In addition, the VOC standard requirements for home appliances are being promoted

3) environmental friendly adsorption materials

internal and external components of home appliances can be used:

pm2.5 adsorption materials (such as visekasone filling)

formaldehyde adsorption materials (active silicon/alumina filling)

negative ion release materials

5 Low cost material module solution

low cost has become an urgent need for the development of home appliances

1) new low-cost functional materials

low-cost polyolefin materials are used, such as high gloss PP instead of ABS, abs/pvc instead of flame retardant ABS

functional parts use plastic instead of steel, copper, glass and aluminum, and mirror PPS with high glass fiber content replaces electroplated metal parts

environmentally friendly high-performance recycled plastics (pp/ps/abs, etc.) replace brand-new materials and comply with the environmental impact assessment tool for electronic products of the United States EPEAT)

2) under the condition of constant strength, reduce the dosage

microporous foaming structural materials (pp/abs/ps, etc.) are used for the internal parts of household appliances

3D printing materials (fdm/sla/sls) are used for rapid sample preparation of household appliances to reduce R & D costs

optimize product structure design through cad/cae, so as to optimize the design of internal and external parts and products of home appliances and reduce consumption

3) industrial chain integration: petrochemical manufacturers can customize modified plastics that can refine grain

petrochemical manufacturers cooperate with modified enterprises to customize specific materials:

high gloss abs/ps/pp

transparent abs/ps/pp

self flame retardant pa6/pa66, long chain nylon, asa

6 Energy saving low carbon material module solutions

1) new low carbon functional materials

skill low carbon has become an inevitable trend in the development of home appliances. Biodegradable materials and their alloys (starch, PLA) can be used as home appliance packaging or non structural parts; Natural fiber reinforced material (PP) can be used to replace glass fiber reinforced material; Ps/abs/pa can be replaced by high heat and weather resistant and high rigid polypropylene, such as PS framework of air conditioner

this is mainly because among the modified plastics for household appliances, polypropylene has the lowest carbon emission index (1.95), and a large number of polypropylene composite skills are used to develop a low-carbon trend, which can reduce costs

2) energy saving and noise reduction functional materials

thermoplastic elastomer materials (pvc/tpv/tpe, etc.) are used for household appliance sealing and shock absorption components

the low-noise fan is made of microcellular foaming material (increase coaxiality, improve dynamic and pragmatic, promote bank enterprise cooperation, and balance the combination of industry and Finance)

the compressor damping pad is made of high damping elastomer material to reduce noise
