Embodiment Construction

[0012] The present invention will be further described below with regard to specific embodiment:

[0013] A production process of a flame-retardant polystyrene foam board, spraying a flame retardant solution on the surface of the polystyrene foam board, and then using vacuum equipment to remove the The flame retardant solution is drawn off, the flame retardant solution is penetrated into the polystyrene foam board and coated on the surface of the polystyrene foam particles, and the polystyrene foam board is dried. Vacuuming equipment can be carried out with a vacuum pump and a vacuum tube. Among them, when spraying, high-pressure nozzles can be used to spray and then atomizing nozzles can be used to further spray, so that the flame retardant solution can fully soak into the polystyrene foam board, and the spraying time of each polystyrene foam board should not be less than 1min. The flame retardant solution includes a modified phosphorus-nitrogen flame retardant, a pH regulat...

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...
