Plastic alloy as well as preparation method and application thereof

Abstract

The invention provides a plastic alloy as well as a preparation method and application thereof, belonging to the technical field of plastics. The plastic alloy comprises the following components in parts by weight: 10-60 parts of PP (Polypropylene) resin, 10-45 parts of PPO (Polyphenylene Oxide) resin, 10.01-42 parts of active kaolin and 5-25 parts of compatilizer. Because the active kaolin subjected to surface treatment and a right amount of compatilizer are used, the plastic alloy has excellent mechanical properties including tensile strength, fracture extension rate, bending strength, bending modulus, notch impact strength, forming shrinkage rate and the like, and the PP resin and the PPO resin have excellent compatibility.

Description

technical field

[0001] The invention belongs to the technical field of plastics, in particular to a plastic alloy, its preparation method and application. Background technique

[0002] Poly(2,6-dimethyl 1,4-phenylene ether) (PPO) is an amorphous polar polymer with a glass transition temperature of about 205°C. Its heat resistance, water resistance, and electrical properties It has excellent physical and mechanical properties, good chemical stability, and is not easy to burn; the disadvantages are high melt viscosity, poor processability, crosslinking tendency, expensive price, and easy stress cracking of products. Polypropylene (PP) is a crystalline non-polar high polymer with low price, non-toxicity, good fluidity, easy processing, waste labor bending resistance, chemical resistance and electrical insulation performance, but it has poor rigidity and large molding shrinkage , Dimensional instability, poor low temperature impact performance and other deficiencies. Mixing PP...
