Problems solved by technology

[0003] Polyphenylene particles are one of the raw materials of polystyrene boards. Polyphenylene particle mortar was once a common product for external insulation due to its special characteristics of inorganic wrapped organic materials and can meet the requirements of Class A fireproof and thermal insulation materials; The on-site construction operation brought a lot of inconvenience, and gradually reduced its use in the market; it was then replaced with a thermal insulation formwork formed by polystyrene particle slurry, but due to its low strength after being formed into a plate, it cannot meet the application requirements
[0004] CN103803907A discloses a foamed insulation board made of cement and polystyrene particles and a preparation method thereof. The foamed insulation board made of cement and polystyrene particles is prepared from the following raw materials according to the stated parts by weight: 150-160 parts of cement , 1.5-2 parts of flame-retardant polystyrene particles, 0.8-1.2 parts of fiber, 6-6.5 parts of foaming agent, 2-3 parts of foam stabilizer, 2.5-3.5 parts of emulsion, 1.5-2.5 parts of waterproofing agent, 50-60℃ 100-12 parts of warm water; although the foam insulation board provided by the patent application has high compressive strength, its pulling strength is low and the application effect is poor

Abstract

The invention provides a caulking reinforcing agent for thermal insulation materials and its preparation method and application. The caulking reinforcing agent comprises the following components: Portland cement, sulphoaluminate cement, ultrafine fly ash, ultrafine Silica fume, penetrant and lubricating flow enhancer. The polystyrene particle insulation board finally prepared by using the gap-filling reinforcing agent provided by the invention has a low thermal conductivity, that is, its thermal insulation performance is good; at the same time, its compressive strength and pull-out strength are high, which can well meet the application requirements. Require.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials, and relates to a joint filling reinforcing agent for thermal insulation materials, a preparation method and application thereof, in particular to a joint filling reinforcing agent for thermal insulation materials with high fluidity, and its preparation method and application. Background technique [0002] Wall insulation is an important part of energy saving and consumption reduction. By setting insulation materials on the wall, it has the effect of thermal insulation, which not only saves energy but also improves the comfort of living. The external wall insulation materials include rock wool and polystyrene board. , extruded plastic board, polystyrene particle slurry, etc. Among them, rock wool is an inorganic material, which not only has the function of thermal insulation but also can play a role in fire prevention. It is one of the more popular thermal insulation materials ...
