Abstract

The invention discloses a stepped flame retardant plastic and a preparation method thereof. The stepped flame retardant plastic comprises the following components by weight: 800-1200 parts of plastic,30-120 parts of inorganic flame retardant powder, 3-8 parts of zinc borate, 2-5 parts of silica powder, 1-2 parts of antismoke agent, 1-2 parts of calcium carbonate, 0.3-1.2 parts of polymeric dispersant, and 0.3-2 parts of auxiliary; the preparation method comprises the following steps: preparing the inorganic flame retardant powder, modifying a flame retardant material, preparing a composite flame retardant material, and preparing the flame retardant plastic. Through the provided stepped flame retardant plastic and the preparation method of the stepped flame retardant plastic, the obtainedplastic forms different flame retardant shells at different temperatures, so that the plastic has a multi-level flame retarding effect, and the stepped flame retarding protection is formed over a plastic base material.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a stepped flame-retardant plastic and a preparation method thereof. Background technique [0002] With the rapid development of polymer materials, electronics, electrical appliances, machinery, automobiles, ships, aerospace and chemical industries, plastic products are more and more widely used in various fields of people's life and production. At the same time, the flammability of plastics causes The fire also brought huge loss of life and property to people. In the prior art, flame retardant properties of plastics are usually improved by adding flame retardants. Flame retardants, also known as flame retardants, fire retardants or fire retardants, are functional materials that endow flammable polymers with flame retardancy. Plastic products processed by flame retardants can be effectively Prevent or terminate the spread of flame, so as to achieve flame retardant effe...
