Abstract

The present invention discloses a stable polypropylene composite material for household electric appliances. The stable polypropylene composite material comprises the following raw materials by weight: 0.4-1 part of diphenylcarbazide, 1-2 parts of elm bark powder, 2-4 parts of iso-octyl methacrylate, 3-5 parts of polyvinylidene fluoride, 1-2 parts of naphthenic oil, 2-4 parts of dry carbide slag, 4-7 parts of stakactite powder, 10-12 parts of gibbsite powder, 0.1-0.3 part of di-n-octyltin bis(isooctyl thioglycolate), 2-4 parts of vinyl carboxylic ester, 0.6-1 part of polyvinyl pyrrolidone, 1-3 parts of polytetrafluoroethylene fibers, 90-97 parts of polypropylene, and 3-4 parts of a modification auxiliary agent. The stable polypropylene composite material of the present invention has characteristics of good dimensional stability, good weather resistance, good surface resistance, good hot-water-resistance, and strong protection property, and is especially adopted as the household electric appliance exterior parts such as the refrigerator top cover, the air conditioner base, the foot bath device and the like.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a stable polypropylene composite material for household appliances. Background technique [0002] Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually translucent colorless solid, odorless and non-toxic. Due to the regular structure and high crystallization, the melting point can be as high as 167°C. Containing cobalt and zirconium, corrosion resistance, and the product can be sterilized by steam are its outstanding advantages. Low density, is the lightest general-purpose plastic. The disadvantage is that it has poor low temperature impact resistance and is easy to age, but it can be overcome by modification respectively; [0003] Polypropylene is a non-toxic, odorless, tasteless milky white highly crystalline polymer, and it is one of the lightest varieties of all plastics. It is particularly stable to water, its water absorption ra...
