Abstract

The invention relates to the technical field of composite boards, in particular to an A-grade flame-retardant polystyrene thermal insulation template, and the template comprises polystyrene boards andpouring slurry between the polystyrene boards, wherein the pouring slurry comprises 100 parts by weight of water, 5-20 parts by weight of a binder, 20-50 parts by weight of a hydroxide flame retardant, 5-20 parts by weight of a silicate charring agent and 0.5-5 part by weight of a foaming agent. The invention further discloses a preparation method of the A-grade flame-retardant polystyrene thermal insulation template, and the preparation method comprises preparation of pouring slurry and bonding and pressing of the boards, wherein the binder comprises the following components: 5-15 parts of an aerogel matrix, 0-10 parts of an aerogel cross-linking agent, 10-50 parts of nano clay, 15-30 parts of aluminum dihydrogen phosphate and 15-30 parts of silica sol. The water, the binder, the flame retardant, the charring agent and the foaming agent are adopted to form the pouring slurry, the pouring slurry is used for bonding all layers of plates, the efficient flame retardant effect can be achieved, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of composite boards, in particular to a class A flame-retardant polystyrene thermal insulation formwork and a preparation method thereof. Background technique [0002] The polymer foam material has excellent comprehensive properties, and has the advantages of light weight, high specific strength, chemical corrosion resistance, thermal insulation, sound absorption and noise reduction, shock absorption, softness, insulation, easy processing and high cost performance. At present, the most important polymer foam materials are expandable polystyrene foam (EPS), extruded polystyrene foam (XPS), polyurethane foam (PU) and polyvinyl chloride foam (PVC). In my country, expandable polystyrene foam is the most used type of foam, and its total production and consumption both rank first in the world. In 2011, the total domestic EPS production has exceeded 4.75 million tons, accounting for more than 75% of the global mark...
