Problems solved by technology

[0002] Polypropylene plastic is a thermoplastic resin produced by the polymerization of propylene. It is usually a translucent colorless solid, odorless and non-toxic. It is the lightest general-purpose plastic. It can be steam sterilized, corrosion-resistant, strong, rigid and transparent. Both are better than polyethylene, but they have poor low-temperature impact resistance and are easy to age. To make polypropylene plastics with better performance and more comprehensive properties, they need to be modified

Abstract

The invention discloses a high-strength mica powder modified polypropylene plastic which is prepared from, by weight, 50-70 parts of polypropylene resin, 20-50 parts of mica powder, 5-10 parts of titanium dioxide, 5-15 parts of brominated epoxy resin, 4-12 parts of silicone oil, 2-8 parts of polyvinyl alcohol, 5-15 parts of tertiary butylhydroquinone, 10-18 parts of dicapryl phthalate, 4-12 parts of heat stabilizer, 10-15 parts of antifreezing agent, 3-9 parts of light stabilizer and 6-10 parts of ferric oxide. According to the high-strength mica powder modified polypropylene plastic, the original characteristics of being resistant to high temperature, nontoxic and odorless of polypropylene plastic are reserved, the added mica powder has insulation, high temperature resistance, acid-base resistance and corrosion resistance, the low-temperature resistance of the plastic is enhanced through the antifreezing agent, the raw materials are easy to obtain, the cost is low, operation is simple, and wide application can be achieved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a high-strength mica powder modified polypropylene plastic. Background technique [0002] Polypropylene plastic is a thermoplastic resin produced by the polymerization of propylene. It is usually a translucent colorless solid, odorless and non-toxic. It is the lightest general-purpose plastic. It can be steam sterilized, corrosion-resistant, strong, rigid and transparent. Both are better than polyethylene, but have poor low-temperature impact resistance and are more prone to aging. To obtain better and more comprehensive polypropylene plastics, they need to be modified. The high-strength mica powder modified polypropylene plastic proposed by the invention can effectively solve the above problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of high-strength mica powder modified polyprop...
