Abstract

The invention relates to a novel light flame-retardant insulating foam shuttering particle material and a preparation method thereof. The light flame-retardant insulating foam shuttering particle material comprises the components as follows: 70-85 weight portions of urea formaldehyde foam plastic, 10-20 weight portions of cellulose solution with the concentration of 15-25 percent and 5-10 weight portions of urea formaldehyde resin adhesive solution with the concentration of 30-50 percent. A layer of hard casing can be formed on the surface of foam, so that the light flame-retardant insulating foam shuttering particle material has the characteristics of light weight, high flame-retardant performance, high heat-resistance temperature of about 215 DEG C to 230 DEG C, good heat preservation and insulation performance, high compressive strength, environmental protection, good size stability, low heat conductivity coefficient, good water resistance and waterproofness and in particular the strong mixing affinity with cement. The light flame-retardant insulating foam shuttering particle material is the core master batch of heat insulation material in the building material field and various fields.

Description

technical field [0001] The invention relates to a novel heat-insulating foam material, in particular to a novel light-weight, flame-retardant, heat-insulating foam mold shell granular material and a preparation method thereof. Background technique [0002] Polystyrene foam application technology is also called benzene board application technology.
