Production process of flame-retarding polystyrene foam board

Abstract

The invention discloses a production process of a flame-retarding polystyrene foam board. The process includes: spraying a flame-retarding agent solution onto the upper or lower surface of a polystyrene foam board; sucking the flame-retarding agent solution, from the corresponding upper or lower surface of the polystyrene foam board, away by using a vacuumizing device; and air-drying the polystyrene foam board. The production process is environment-friendly and the product has good flame-retarding effect.

Description

Technical field: [0001] The invention relates to the field of building boards, in particular to a production process of flame-retardant polystyrene foam boards. Background technique: [0002] Polystyrene foam (EPS) panels are a potential fire hazard as an organic insulation material. Therefore, it is extremely important to study the flame retardant modification of EPS. In the prior art, the flame retardant modification of EPS is mainly realized by adding a flame retardant. Additive flame retardants can be divided into two categories: organic flame retardants and inorganic flame retardants according to their chemical composition. Inorganic flame retardants such as magnesium hydroxide, aluminum hydroxide, antimony trioxide, etc. have the advantages of low smoke, low toxicity, halogen-free, good stability and low price, but there are large amounts of addition and poor compatibility with materials , Reduce material properties and other shortcomings, are limited to a certain e...

Problems solved by technology

Inorganic flame retardants such as magnesium hydroxide, aluminum hydroxide, antimony trioxide, etc. have the advantages of low smoke, low toxicity, halogen-free, good stability and low price, but there are large amounts of addition and poor compatibility with materials , Reduce material properties and other shortcomings, subject to certain restrictions

Organic flame retardants are mainly halogenated flame retardants, such as decabromodiphenylene, decabromodiphenyl ether, etc. Although this series of flame retardants have good compatibility with materials, small addition amount, high cost performance, and The performance of the material has the advantages of small impact, but when it is flame retardant, it will produce a large amount of toxic gases such as hydrogen halide, which is harmful to humans and the environment.

Moreover, more importantly, the current flame-retardant and flame-retardant polystyrene foam boards are realized by mixing and adding flame retardants during the production and preparation of polystyrene foam boards. The burning effect is not good, and crystallization and powder fall off when exposed to fire
