Problems solved by technology

However, this type of flame retardant has an insurmountable disadvantage, that is, to achieve a good flame retardant level, it must be added in large quantities, usually greater than 50%, which causes a serious increase in the specific gravity of the plastic, and then loses the advantage of small specific gravity. Poor processing performance and reduced toughness, thus limiting its application fields

Abstract

The invention relates to a high-stability halogen-free environmental-friendly fire retardant used for plastic, and a preparation method thereof. The high-stability halogen-free environmental-friendlyfire retardant used for plastic is prepared from, by weight, 45 to 80 parts of modified polyorganosiloxane, 20 to 32 parts of fumed silica, 8 to 15 parts of modified diatomite, 2 to 5 parts of a surface treatment agent, and 1 to 2 parts of polyethylene wax. Compared with the prior art, the high-stability halogen-free environmental-friendly fire retardant is excellent in flame resistance, smoking inhibition effect, and plastifying effect, is safe and reliable, is low in cost, contains no toxic additive, is capable of improving mechanical process performance, flame resistance, and heat resistance of base materials, reducing smoke formation amount effectively, inhibiting generation of carbon dioxide, and satisfying novel type fire retardant halogen-free phosphorus-free environmental-protection requirements; the raw materials are widely available.

Description

technical field [0001] The invention belongs to the field of flame retardant technology, and relates to a high-stability halogen-free environment-friendly flame retardant for plastics and a preparation method thereof. Background technique [0002] As we all know, plastic, as a synthetic polymer material, has been widely used in people due to its good formability, film formation, insulation, acid and alkali resistance, low air permeability, water permeability, and easy coloring. all aspects of life. However, plastics and most polymer materials are flammable materials, which will produce a lot of smoke and toxic gases when burned, which not only pollute the environment, but also seriously endanger people's health, and even cause people to be poisoned and die. social issues of concern. In order to do our best to reduce the fire hazard of plastics, how to improve the flame retardancy of plastic materials has become an urgent problem to be solved in the current research of plas...
