Problems solved by technology

[0004] Although the existing patents CN201610343595 and CN201610844226 proposed the method of using negative pressure to suck cement into the polystyrene insulation board, they simply added a water reducing agent to increase its fluidity, and did not consider the relationship between the inorganic modified slurry and polystyrene. Due to the problem of interface compatibility, the strength of the board cannot be improved, which will cause safety hazards in later use, and when the water ash is relatively large, the cement is prone to water phenomenon, which is difficult to operate in actual production

Abstract

The invention provides inorganic slurry for a thermosetting compound polystyrene board. The inorganic slurry is prepared from the following components in parts by weight: 80-100 parts of silicate cement, 0.1-10 part of enhancer, 0-10 parts of a suspending agent, 0-3 parts of a thickening agent, 0-5 parts of interface adhesive, 0-3 parts of water reducer, 0-1 part of surfactant, 0-2 part of retarder and 50-70 parts of water, wherein the enhancer is prepared from one or more of high-alumina cement, calcium sulphoaluminate and calcium formate. The invention further provides a preparation method of the inorganic slurry. The board produced from the inorganic slurry has a heat conductivity coefficient controlled to be 0.050 or less, is A-class non-combustible, has high strength and good integration with a substrate wall, does not have potential safety hazard, is relatively low in cost, and is easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of modification of polystyrene insulation boards, and in particular relates to an inorganic slurry of thermosetting composite polystyrene boards and a preparation method thereof. Background technique [0002] Polystyrene insulation board is the most commonly used type of insulation board, but its fire performance is poor, and its thermosetting is also poor. In the prior art, inorganic materials are commonly used to modify polystyrene insulation boards to enhance their fireproof performance. The production process of thermosetting composite polystyrene board is divided into three types, infiltration type, molded type and pouring type. Among them, the infiltration type has the advantages of light weight, low thermal conductivity and large production capacity, and is the main production process for producing thermosetting composite polystyrene boards. [0003] At present, the osmotic production process mainly...
