Abstract

The invention provides a high-molecular flame-retardant foam material which is prepared by mixing the following components in parts by weight: 83.5 to 97.5 parts of polymer resin, 1.8 to 8.8 parts of flame retardant, 0.4 to 4.2 parts of surface active agent and 2 to 15 parts of polystyrene foam particles. The preparation method of the high-molecular flame-retardant foaming heat insulating material comprises the following steps: the polymer resin, the flame retardant and the surface active agent are mixed uniformly to prepare a high-molecular organic flame-retardant adhesive, then after being mixed, the high-molecular organic flame-retardant adhesive and a curing agent are added into the polystyrene foam particles, and the high-molecular flame-retardant foaming heat insulating material can be formed quickly through hot pressing. The high-molecular flame-retardant foam material provided by the invention synthesizes the characteristic of low heat conductivity coefficient of the foam particles and efficient flame-retardant effect of the high-molecular organic flame-retardant adhesive, really achives integration of flame retardance and heat preservation, and uses various flame-retardant compounds for mixing to form the flame retardant, and the prepared high-molecular flame-retardant foaming heat insulating material is better in flame retardant property, better in thermal insulation effect, and higher in oxygen indexes.

Description

technical field [0001] The invention relates to the field of flame-retardant foam insulation materials, in particular to a preparation method of a polymer flame-retardant foam material, which has broad application prospects in the fields of external wall insulation and vehicle insulation. Background technique [0002] External wall insulation is a thermal insulation method that places the insulation layer outside the main wall material. Because it can reduce the impact of cold bridges and protect the main wall material from large temperature deformation stress, it has become the most widely used thermal insulation method. It is also the practice of heat preservation vigorously advocated by the state. Due to the occurrence of many building insulation fire incidents in recent years, it has triggered the thinking of all walks of life on thermal insulation and fire prevention. The fire performance of thermal insulation materials has attracted unprecedented attention from all wal...
