Problems solved by technology

In addition, the existing production process of flame-retardant foaming materials still has defects, because in order to achieve a good flame-retardant effect, the amount of flame retardant must be increased during production, which not only causes uneven decomposition of the material, affects the function, but also fails to achieve the highest environmental protection. standard

Abstract

The invention relates to a formula and a manufacturing process of a flame-retardant low-smoke material. The process comprises the steps of subjecting plastics, pozzuolana powder, montmorillonite powder, a flame retardant agent and other chemical additives to preparation, internal mixing and open milling, cutting into slices of semi-finished products, conducting foam molding through a foaming machine. The flame-retardant low-smoke material comprises, by mass, 6-6.5 parts of plastics, 1.5-2 parts of the pozzuolana powder, 1.5-2.5 parts of the montmorillonite powder, 2-2.5 parts of the flame retardant agent and 0.5-1 part of chemical additives. The flame-retardant low-smoke material is obvious in flame-retardant low-smoke effect, and compared with existing like products, the flame-retardant low-smoke material is low in cost, environment-friendly in material, free of poison and complete in technical scheme.

Description

Technical field: [0001] The invention relates to a flame-retardant and low-smoke material and a manufacturing process thereof, in particular to a formulation of a plastic foam material with flame-retardant and low-smoke effects and environmental protection and a manufacturing process thereof. The plastic foam of the present invention (also known as EVA foam or cross-linked foam). Background technique: [0002] Existing commonly used flame retardant plastic foam materials, including ethylene-vinyl acetate copolymer, high pressure low density polyethylene, low pressure high density polyethylene, high and low pressure composite polyethylene and flame retardants, chemical additives, calcium carbonate fillers, etc. , Although the products foamed with these materials have a certain flame retardant function and environmental protection effect, they cannot meet the high standard requirements (usually high temperature resistance is only about 130 ° C ~ 150 ° C), which is far from mee...
