A kind of superfine pure white inorganic fiber coating

Abstract

The invention discloses an ultrafine pure-white inorganic fiber coating. The inorganic fiber coating is prepared from the following ingredients in a certain proportioning ratio: 500-550 units (by weight) of inorganic fibers, 150-200 units (by weight) of glass micro-beads, 20-30 units (by weight) of nano heat insulating material, 200-300 units (by weight) of cement, 30-50 units (by weight) of polymer rubber powder and 5-10 units (by weight) of cellulose; and when the coating is used, a coating layer with certain thickness can be formed through adding 200-300 units (by weight) of water into the inorganic fiber coating, carrying out low-speed uniform stirring, coating a substrate wall with the mixture, and carrying out drying. According to the inorganic fiber coat, the ultrafine inorganic fibers and the pure-white nano glass micro-beads serve as a heat preservation base material, a nano-scale heat preservation material, which takes the vacuum glass micro-beads with nano ingredients as aggregates, is added on the basis of making full use of the fire resistance and heat preservation property of the inorganic fibers, and the heat conduction and heat convection between the fibers and the glass micro-beads are cut off by using the ultralow heat insulating performance of the nano-material, so that superior heat preservation and heat insulating properties are shown.

Description

technical field [0001] The invention relates to the field of building thermal insulation materials, in particular to an ultrafine pure white inorganic fiber coating, and the building thermal insulation coating produced by using the coating has good thermal insulation effect. Background technique [0002] At present, the thermal insulation mortar on the market mainly includes inorganic thermal insulation mortar and organic thermal insulation mortar; the main components of the former are aggregate (perlite), cementitious material (cement) and other admixtures. The quality of raw materials is uneven, and the quality of products is not guaranteed; so that problems such as cracking and hollowing often occur, the repair rate is high, and the safety is poor. This material has tended to be eliminated; the latter is mainly composed of polyphenylene particles and gelling materials. Two-component thermal insulation materials, due to the existence of organic materials, cannot achieve Cl...

Problems solved by technology

[0002] At present, the thermal insulation mortar on the market mainly includes inorganic thermal insulation mortar and organic thermal insulation mortar; the main components of the former are aggregate (perlite), cementitious material (cement) and other admixtures. The quality of raw materials is uneven, and the quality of products is not guaranteed; so that problems such as cracking and hollowing often occur, the repair rate is high, and the safety is poor. This material has tended to be eliminated; the latter is mainly composed of polyphenylene particles and gelling materials. Two-component thermal insulation materials, due to the existence of organic materials, cannot achieve Class A fire protection in terms of fire resistance, and with the improvement of national energy conservation requirements, the thermal conductivity of this material is relatively high, and the thickness of the insulation layer is too thick. market acceptance
