Abstract

The invention discloses a punching-resistant modified plastic which is prepared from the following raw materials in parts by weight: 40-60 parts of polystyrene, 8-10 parts of high-density polyethylene, 10-20 parts of polycaprolactone, 5-8 parts of nano filler, 2-6 parts of coupling agent, 2-5 parts of reinforcing agent and 2.5-4.5 parts of impact-resistance modifier. The modified plastic has very high punching resistance, and also has wear resistance and heat resistance; and the product also has the same properties, and has the advantages of high elasticity, crack resistance and very high practicality.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a stamping-resistant modified plastic. Background technique [0002] Both polyethylene and polypropylene are commonly used materials for making plastics, but polyethylene has low impact strength, poor elasticity and stress crack resistance, and polypropylene has good corrosion resistance, rigidity and transparency, but this plastic is resistant to Thermal, hardness and impact resistance are poor. All therefore limit their use [0003] At present, research on impact-resistant plastics, which are widely used in the field of people's livelihood, is the top priority. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a stamping-resistant modified plastic, which can improve its low-temperature brittleness by adding toughening agent, coupling agent, reinforcing agent, toughening agent and impact modifier to polystyrene , so as to im...
