Microhollow super-fibre heat insulation coatings for building insulation and method of use thereof

Abstract

The invention provides a micro hollow fiber thermal insulating coating for buildings and an application method thereof. The micro hollow fiber thermal insulating coating for buildings is divided into a I-type single-component micro hollow fiber thermal insulating coating for buildings and a II-type double-component micro hollow fiber thermal insulating coating for buildings, and is used as an exterior wall thermal insulating coating or used to pipes and other various places needing coating the thermal insulating coating. The coating is added with super hollow fibers and aramid fibers with high-temperature resistance, acid and alkali resistance and light weight, so that the coating has the advantages of low thermal coefficient and heat storage coefficient, obvious heat retaining effect, nontoxic formula, environmental protection, excellent fire resistance, super-strong chemical stability, high cohesional strength, noise removal, high cost performance, long service life, wide application, simple and easy construction, good effect, labor and physical resource conservation, and obvious economic and environment-friendly benefits.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically relates to a micro-hollow microfiber building thermal insulation coating and its application method. Background technique [0002] At present, it is a traditional polystyrene thermal insulation material widely used in building wall thermal insulation projects, which has the following disadvantages: The disadvantages of the expanded polystyrene board thin plaster external wall thermal insulation system are: poor fire resistance and water seepage resistance, The process is complicated and the project cost is high (the cost of materials per square meter is 70-80 yuan); the wind pressure and impact resistance and the firmness of the insulation layer are poor, and the service life is short. Large areas of cracks, hollowing, falling off, etc., or because the rivets are not firmly riveted or the rivets are rusted, the foam board and extruded board slowly degrade and the surface la...

[0002] At present, it is a traditional polystyrene thermal insulation material widely used in building wall thermal insulation projects, which has the following disadvantages: The disadvantages of the expanded polystyrene board thin plaster external wall thermal insulation system are: poor fire resistance and water seepage resistance, The process is complicated and the project cost is high (the cost of materials per square meter is 70-80 yuan); the wind pressure and impact resistance and the firmness of the insulation layer are poor, and the service life is short. Large areas of cracks, hollowing, falling off, etc., or because the rivets are not firmly riveted or the rivets are rusted, the foam board and extruded board slowly degrade and the surface layer cannot use oily solvent-based paint, etc. Once the above problems occur, repair or The cost of rework is quite high

The disadvantages of the polystyrene particle thermal insulation slurry thermal insulation system are: firstly, the fire prevention and impermeability are poor, and it is prone to cracks, hollows, and shedding; secondly, there is an irreconcilable contradiction between the thermal insulation effect of the system and the strength of the thermal insulation layer: To improve the thermal insulation effect, it is necessary to increase the content of polyphenylene particles in the slurry and reduce the content of cement mortar, resulting in insufficient strength of the insulation layer; if the strength of the insulation layer is emphasized, it is necessary to increase the content of cement mortar in the slurry and reduce the content of polyphenylene particles, resulting in insufficient insulation strength.
