Making method of fire-retardant heat insulation EPS board

Abstract

A making method of a fire-retardant heat insulation EPS board is provided to solve a technical problem of the low fire retardation performance of present fire-retardant heat insulation EPS boards. A technical scheme adopted in the invention is characterized in that the method comprises the following steps: foaming raw materials in a foaming machine to prepare foam particles, heating, compressing and molding the foam particles in a board making molding machine to form a board, drying, and cutting; and the method also comprises a film coating operation, a fire-retardant adhesive film is coated on the external surface of the foam particles after the preparation of the foam particles in the foaming machine, and then the foam particles are put in the board making molding machine for board making. The method has the advantages of reasonable structural design, simple and convenient operation, and improvement of the fire retardation performance of the fire-retardant heat insulation EPS board, and makes the fire-retardant heat insulation EPS board to have the excellent characteristics of no fusion and no flow, have the fire retardation, fire source isolation and flame spreading prevention effects, and provide a guarantee for the effective protection of the life and property safety, so the fire-retardant heat insulation EPS board is a very ideal environmentally-friendly heat insulation material having the advantages of fire retardation, heat insulation, energy saving and beauty.

Description

technical field [0001] The invention belongs to the technical field of EPS production equipment, and relates to a production line system of EPS thermal insulation and fireproof boards, in particular to a method for manufacturing EPS thermal insulation and fireproof boards. Background technique [0002] EPS thermal insulation board is a commonly used building heat insulation, fire prevention, and thermal insulation material. It is not only effective, economical, but also simple in construction and high in efficiency. It is widely used in building walls, roof insulation, and insulation layers of composite insulation panels. field. At present, the production line system of EPS thermal insulation board includes raw material warehouse, foaming machine, board forming machine, drying room, and cutting system. The flame retardant added in the production process cannot play a good flame retardant effect, resulting in external factors Large fires caused by defects in wall insulation ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the technical problem of the low flame retardant performance of the existing EPS thermal insulation and fireproof board. In order to solve this problem, we have designed a production method of EPS thermal insulation and fireproof board. Film coating, reasonable structural design, simple and convenient operation, improves the flame retardant performance of the EPS thermal insulation fireproof board, makes the EPS thermal insulation fireproof board have the characteristics of flame retardant, insoluble, and self-extinguishing when it is away from the fire, and injects the flame retardant insulation material for the outer wall New vitality, expanded development space
