Single-component polyphenyl particle heat-insulating mortar

Abstract

The invention discloses mono-component polyphenyl particle heat preservation mortar, which is prepared by the mixing and dispersing of polyphenyl particles and the following components in weight percentage(total 100 percent): 0.2 to 1 percent of methyl cellulose, 0.2 to 1 percent of lignocellulose, 10 to 35 percent of fly ash, 39 to 77 percent of 425 Portland cement, 10 to 35 percent of dispersing emulsion powder, 0.2 to 0.5 percent of polypropylene cut fiber, 1 to 15 percent of mica powder, 0.05 to 1 percent of starch ether, 1 to 10 percent of quick lime, 0.1 to 1 percent of dry powder defoaming agent and 1 to 15 percent of organic expansion agent. The blending ratio of the components to the polyphenylene particle is between 6 and 10m<3> / t. The mortar has the characteristics of heat preservation, energy conservation, heat insulation and water resistance, light weight, high strength, strong anti-rainfall erosion capability, no loosening after long-time water soaking, low thermal conductivity, good performance, no toxin and pollution and the like; and the compression resistance and the bonding strength both meet the plastering requirement, so that the mortar is widely applied to one-time plastering during the construction of a heat preservation layer.

Description

technical field [0001] The invention relates to a thermal insulation mortar, in particular to a single-component polystyrene particle thermal insulation mortar, which can replace various plastering mortars on the wall, and can be applied to the outside of the building wall to form an external thermal insulation layer, which can be widely used for thermal insulation One-time painting during layer construction. Background technique [0002] After the 1970s, foreign countries generally paid attention to the production of thermal insulation materials and their application in construction, and strived to greatly reduce energy consumption, thereby reducing environmental pollution and greenhouse effect. The thermal insulation material industry in foreign countries has a long history, and thermal insulation materials for building energy conservation account for the vast majority. Cotton products are used for energy saving in buildings. Some foreign developed countries have already...

Problems solved by technology

The main problems of this system are: the water absorption rate of the system is relatively large, it is easy to crack if it is not handled properly, the insulation effect is poor, and the construction regulations are very chaotic. Some people do high-rise external insulation and directly paste bricks on the insulation mortar. The safety is worth worrying about.
