Problems solved by technology

[0003]At present, building insulation materials mainly include inorganic and organic materials. Aging and low price and other characteristics, but poor thermal insulation efficiency, heavy weight, can not be used in high-rise buildings
Organic insulation materials are mainly foamed plastics. The main products are polystyrene foam, phenolic foam and polyurethane foam. The main disadvantages are flammability, dripping and melting, large combustion smoke, high toxicity, and hydrogen cyanide gas. , Once a fire breaks out, it is extremely toxic to the human body
The current organic thermal insulation materials have a large market demand, mature production technology, light weight, and easy installation. The main disadvantage is that the fire resistance cannot meet the requirements.

Abstract

The invention relates to a preparation method of a polymer composite foam material. The method comprises the following steps: 1, banburying, namely mixing the raw materials at a certain mass ratio, then adding the mixture into an internal mixer, and performing internal mixing at a temperature of 90+ / -5 DEG C for 6-8 hours; 2, discharging the mixture to a single screw extruder and extruding; 3, feeding a panel to a high-temperature foaming furnace and performing curing foaming; 4, cutting and tailoring the panel into sheets, so as to prepare the product. The prepared material disclosed by the invention has the characteristics of being good in heat insulation and heat preservation effects, light in weight, environment-friendly and non-toxic, convenient to install, and low in price, can achieve the A grade of flame retardant requirements, and can be applied to the fields of high-rise buildings, residential houses, ship engineering, cold storage, petrochemical engineering, chemical engineering, defense-related science and technology, cold insulation engineering of military industry and the like.

Description

technical field [0001] The invention relates to a high-filling, energy-saving, heat-retaining, fireproof polymer composite foaming material and a preparation method thereof. Through the use of special rubber and plastic processing equipment, a large amount of flame retardants and fireproofing agents are filled into the high molecular polymers. The high molecular polymers are only used as skeleton materials to bond the flame retardants and fireproofing agents together to meet the fire protection requirements. Through The high-temperature foaming process enables the product to have high thermal insulation performance. Background technique [0002] At present, high-rise buildings, residential buildings, cold storage, ship engineering, petrochemical and other fields require thermal insulation materials to have better energy-saving thermal insulation performance and fire performance, especially for high-rise buildings, which are required to meet the requirements of Class A fire p...
