Abstract

The present invention relates to the technical field of building materials, particularly to a polymerization polystyrene plate and a preparation method thereof. According to the polymerization polystyrene plate, 20-50 kg of an inorganic fireproof material and 0.4-5 kg of a curing agent are injected into an expanded polystyrene plate with a unit volume of one cubic meter. The preparation method comprises: 1, uniformly stirring an inorganic fireproof material and a curing agent in the claim 1 at a speed of 800-1000 r/min so as to be adopted as a mixture; 2, injecting the mixture into an expanded polystyrene plate; and 3, conveying the expanded polystyrene plate injected with the mixture into a laminating machine to mold, wherein the molding temperature is 35-70 DEG C, and the time is 4-15 min. According to the present invention, when contacting fire, the polymerization polystyrene plate does not shrink, does not produce droplets, does not burn, does not produce smoke and is not be penetrated by flames; and the polymerization polystyrene plate further has characteristics of good thermal insulation property, low thermal conductivity and no influence on thermal insulation effect after long term use, and can be provided for reducing even eliminating occurrence of fire disasters similar to the Shanghai 2010 11.15 disastrous fire from the source head so as to protect life and property safety of the majority of the public.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a polymerized polystyrene board (in this technical field, the polymerized polystyrene board is referred to as a polymerized polystyrene board for short) and a preparation method thereof. Background technique [0002] Building energy conservation is a sustainable development strategy advocated by our government in recent years, and the strategy of rejuvenating the country through science and education is an important national policy that contributes to energy conservation and environmental protection. Therefore, vigorously developing energy-saving buildings has become a consensus. In 1986, my country promulgated the first "Civil Building Energy Conservation Design Standard" for trial implementation, and then formulated different building energy conservation design standards according to my country's national conditions to meet the national building energy conservation r...
