Abstract

The present invention discloses a bursting-resistant and heat-resistant polypropylene composite material, which comprises the following raw materials by weight: 0.5-1 part of manganese isooctanoate, 1-2 parts of sodium aluminate, 2-3 parts of tar slag, 2-4 parts of volcanic ash, 0.2-1 part of calcium alginate, 2-4 parts of butyl acrylate, 2-3 parts of barium metaborate, 2-3 parts of 1,4-cyclohexanedimethanol, 3-5 parts of diethyl phthalate, 0.6-1 part of stearamide, 2-4 parts of ethyleneglycol dimethacrylate, 10-15 parts of vermiculite powder, 92-100 parts of polypropylene, 2-4 parts of calcium fluoride, and 3-4 parts of a modification auxiliary agent. The bursting-resistant and heat-resistant polypropylene composite material of the present invention has characteristics of strong high-temperature-resistance, good toughness, high squeezing-pressure-resistance, bursting resistance during a construction process, good safety and good stability, and is particularly suitable for producing low-cost living goods.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to an anti-explosion heat-resistant polypropylene composite material. 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 rat...
