Fireproof thermal-insulation composite slurry with strong adhesive force

Abstract

The invention discloses a fireproof thermal-insulation composite slurry with a strong adhesive force. The slurry is characterized by being composed of the following components in parts by weight: 15 to 20 parts of cement, 3 to 5 parts of latex powder, 5 to 7 parts of cellulose ether, 1 to 1.5 parts of fiber additive, 8 to 12 parts of perlite, 0.4 to 0.7 part of coconut oil, 0.1 to 0.3 part of vitamin E, 12 to 15 parts of polystyrene foamed powder, 0.8 to 1 part of dispersible rubber powder, 0.5 to 0.6 part of sodium alginate, 0.5 to 0.8 part of vinegar-dissolved chitosan, 0.6 to 0.8 part of sodium polyacrylate, 0.3 to 0.6 part of air entraining agent, and 100 parts of water. The obtained slurry has the characteristics of excellent adhesive strength, thermal insulation performance and overall strength, good waterproof and fireproof effect, and improved adhesive force, is capable of effectively preventing the shrinking and cracking of cement, and has the advantages of energy efficiency, environment-friendliness, no toxicity, no pollution, high value, and low cost.

Description

Technical field [0001] The invention relates to the field of building slurry, in particular to a fireproof and thermal insulation composite slurry with strong adhesion. Background technique [0002] A large number of air conditioners are used every summer, which brings environmental problems that cannot be ignored. Building constant temperature materials can not only be mixed with water-based coatings, but also can be combined with cement, mortar, lime, gypsum, fly ash, and concrete to form a constant temperature layer for indoor and outdoor walls to achieve the purpose of indoor and outdoor wall cooling in summer and warm in winter. [0003] At present, my country implements building energy-saving projects, external wall insulation, and many projects choose polymer mortar insulation products such as rubber powder polystyrene particles, expanded perlite, etc., but in actual use, cracking, deformation, and shedding have occurred to varying degrees. , There are serious quality proble...

AI Technical Summary

Problems solved by technology

The polystyrene particle mortar system in the prior art is simple in construction, but its disadvantages are poor bonding strength, high water absorption, and easy cracking and leakage

The blocking effect on heat convection and sunlight radiation is poor, and the crack resistance and waterproof ability are also poor, which cannot meet the new requirements of building energy saving, leakage prevention and fire prevention.
