The plastic for the home appliance comprises the following components in parts by weight: 50-70 parts of PC resin, 30-50 parts of ABS resin and 2-8 parts of a compatilizer. The plastic for the home appliance combines excellent characteristics of PC and ABS materials, has good mouldability, mechanical properties, impact strength, temperature resistance and ultraviolet resistance and can be widely applied to manufacturing of refrigerators, washing machines, water dispensers, electric cookers, air freshening machines and the like.
Description
Technical field
The present invention relates to a kind of plastics and preparation method thereof, relate in particular to a kind of plastics for home appliances and preparation method thereof.
Background technology
Domestic household electrical appliances market will welcome the quick upgrading of new round consumption structure, and this will effectively promote the growth of domestic consumption market." and the chemical materialss such as plastics and household appliances manufacturing are in close relations, therefore must coordinate the upgrading of household electrical appliances, progressively to customizations, high performance, safety, the effort of environmental protection direction.
Plastics major part for household electrical appliances is thermoplastics, accounts for 90%, and wherein major part is general-purpose plastics, mainly contains following a few class.
1, general-purpose plastics: polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC) etc.
2, engineering plastics: acrylonitrile/butadiene/styrene terpolymer (ABS), polymeric amide (PA), polycarbonate (PC), polyoxymethylene (POM), polyphenylene oxide (PPO), polyethylene terephthalate (PET), polybutylene terephthalate (PBT), urethane (PUR) etc.
3, thermosetting resin: resol, aminoresin, epoxy resin etc.
Because plastics have light weight, electrical insulation capability that intensity is high, excellent, good chemical stability, good printing opacity and barrier propterty and damping, performance muffler suddenly become the indispensable material of household appliances manufacturing.
Plastics consumption in household electrical appliances, has accounted for 40% of weight ratio at present.Along with household appliance appearance is more and more diversified, art up, special-effect plastics are proposed to requirements at the higher level.In the situation that ensureing product performance, by adopting novel material, new design, novel process.
Along with the further attention of people to health, the antibacterial of household electrical appliances and sterilizing function plastics have been proposed to higher, more normalized requirement, it is reported increasing enterprise by antibiotic plastic for refrigerator, washing machine, water dispenser, electric cooker, air cleaner etc. to reduce microbial contamination and germ cross infection.
In addition, in household electric appliances, product plastic has become one of household electric appliances important development direction, and plastics have become the fastest material of field of household appliances application quantity rate of growth, and every average annual growth rate reached 29.5% left and right in recent years.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention is to provide a kind of plastics for home appliances.
Two of technical problem to be solved by this invention is to provide the preparation method of above-mentioned plastics for home appliances.
