Problems solved by technology

[0006] The technical problem to be solved by the present invention is: in order to solve the problem that traditional EPS boards are flammable and produce poisonous gas and dense smoke when burned, and for the existing fire-proof EPS boards, although the fire-proof performance has been improved, but in terms of thermal insulation performance, bulk density, etc. To improve the performance of poor water absorption and other aspects, the present invention provides a fireproof inorganic modified polystyrene board, which can insulate flammable polystyrene from the air by coating polystyrene particles and prevent it from burning. solve the above problems

Abstract

The invention provides a fireproof inorganic modified polystyrene board which comprises multiple polystyrene particles which are fixedly connected into a whole and have the granularity of 2-5mm, and a fireproof material coated on the polystyrene particles, wherein a weight ratio of the polystyrene particles to the fireproof material is (1:7)-(1:11). The inorganic modified polystyrene board has excellent heat insulation capacity and excellent heat insulation effect and is low in volume weight and difficult to drop. Moreover, according to the presence of the fireproof material, gaps among the polystyrene particles are far smaller than a closed pore structure of the traditional EPS board, the water-absorbing quality is greatly reduced, long-term use of the fireproof inorganic modified polystyrene board is promoted, and the potential safety hazard is eliminated.

Description

technical field [0001] The invention relates to the technical field of building heat preservation, in particular to a fireproof inorganic modified polystyrene board. Background technique [0002] At present, building insulation materials on the market include polystyrene board, phenolic board, rigid foam composite polyurethane board, rock wool, thermal insulation mortar, and foamed cement board. It is mature, and there are still problems such as high water absorption that have not been resolved, and it is difficult to popularize and apply in the short term; the combustion performance index of rigid foam composite polyurethane board can only reach B in GB8624-2012 "Classification of Combustion Performance of Building Materials and Products". 1 level, and the technical threshold is high, it is difficult for general enterprises to meet the requirements of product production, resulting in high product prices and greatly increasing construction costs; while rock wool, thermal...
