Abstract

The invention discloses a composite inorganic flame-retardant master batch and a preparation method thereof. The master batch comprises the following components in parts by weight: 10-15 parts of EVAresin, 50-65 parts of inorganic flame-retardant powder, 10-25 parts of zinc borate, 10-20 parts of calcium carbonate, 10-20 parts of aluminum hydroxide, 4-6 parts of PE wax, 1-5 parts of a coupling agent and 0.5-1.5 parts of a surfactant; the preparation method comprises the following steps: superfine treatment of the inorganic flame-retardant powder, preparation of the composite inorganic flame-retardant material and preparation of the composite inorganic flame-retardant master batch. According to the composite inorganic flame-retardant master batch and the preparation method thereof providedby the invention, the obtained master batch has multiple flame-retardant effects in a relatively wide temperature range, has the characteristics of convenience in addition and good compatibility anddispersity with plastics, and is simple in preparation method, free of special heating and cooling steps, time-saving, labor-saving and easy to realize.

Description

technical field [0001] The invention relates to the technical field of flame retardant materials, in particular to a composite inorganic flame retardant masterbatch and a preparation method thereof. Background technique [0002] Flame retardants, also known as flame retardants, fire retardants or fire retardants, are functional materials that endow flammable polymers with flame retardancy. In plastic products, flame retardants are usually added to improve the flame retardancy of products, especially wires. Cables, home improvement profiles, plastic floors, etc. require their flame retardancy to meet certain standards, so that when they are attacked by an external fire source, they can win a certain rescue time and protect human life and property safety. [0003] Existing flame retardants mainly include two categories, halogenated flame retardants and non-halogenated flame retardants. Among them, halogenated flame retardants will release toxic and harmful fumes during combust...
