Foam insulation board with flame retardation function

Abstract

The invention discloses a foam insulation board with a flame retardation function. A preparation method for the foam insulation board comprises the following steps: (1) coating of EPS particles: weighing 100 parts of prefoamed and cured EPS particles and 150 to 200 parts of a flame-retardant adhesive, carrying out uniform mixing under stirring, adding 10 to 15 parts of a curing agent and continuing stirring so as to obtain uniformly coated EPS particles; (2) gelation: subjecting the uniformly coated EPS particles to microwave heating for drying for 0.5 min and then delivering hot air for drying for 1 to 2 min so as to obtain gelated foam EPS particles; and (3) compression molding: putting the uniformly coated EPS foam particles into a die, closing the die, introducing water vapor with pressure intensity of 0.06 to 0.08 Mpa, maintaining the pressure for 1 to 2 min and then successively carrying out pressure relief, cooling and die-opening. The foam insulation board provided by the invention has good production efficiency, good flame retardation effect and high comprehensive properties.

Description

technical field [0001] The invention relates to a decorative board, in particular to a foam insulation board with flame-retardant function. Background technique [0002] Since the early 1990s in my country, the research and development of phenolic foam technology has been rapid. Phenolic foam board is an organic thermosetting rigid foam insulation material, which has the characteristics of low bulk density, low thermal conductivity, good fire performance and convenient construction of organic insulation materials. Especially in recent years, with the gradual improvement of my country's building energy saving rate and fire protection level, the unique properties of phenolic foam such as outstanding fire resistance, flame penetration resistance, low smoke, low toxicity and high temperature resistance have shown advantages, and are more suitable for energy-saving building insulation systems.

Problems solved by technology

[0003] However, the phenolic foam board currently on the market is too brittle, easy to drop powder, low in elasticity, and low in compressive strength. Moreover, this kind of insulation board has poor flame retardancy, easy to catch fire, easy to drip and melt, and there is a great fire hazard.

The increase in the number of high-rise buildings in major cities across the country and the continuous rise of high-rise buildings have brought great difficulties to fire prevention. Once a fire breaks out, it is easy to cause heavy casualties, economic and property losses because it cannot be extinguished from the outside like ordinary buildings.
