Water-based vacuum ceramic microbead insulation paint used for textile fabric substrates and preparation method thereof

Abstract

The invention discloses a water-based vacuum ceramic microbead insulation paint used for textile fabric substrates and a preparation method thereof. The paint consists of one-component waterborne polyether polyurethane resin, organic-inorganic hybrid resin, a reflective functional filler, vacuum ceramic microbeads, an auxiliary pigment and filler, and an auxiliary agent. A coating adopts the vacuum ceramic microbeads with bi-gradation model ratios to make arrangement more compact, so that the coating cured at a normal temperature has a lower heat conductivity coefficient, and the heat insulation performance of the coating can be significantly enhanced; the vacuum ceramic microbeads can enhance the compatibility between the resin and the microbeads after being processed by the organic-inorganic hybrid resin, so that the adhesive force between the coating and base materials can be significantly improved; and the auxiliary pigment and filler have reflection functions, so that a paint filmcan have higher reflectivity and reflect most of sunlight. The coating has good compatibility with fabric base materials, and is excellent in adhesive force, flex resistance, intensity and scratch resistance, so that demands of repeatedly folding textile fabrics can be met; and the paint is excellent in heat insulation performance, thermal insulation temperature difference can reach more than 12DEG C, and therefore, water-based environmental protection can be achieved.

Description

technical field [0001] The invention belongs to the field of heat-insulating coatings and coatings, and relates to a water-based vacuum ceramic microbead heat-insulating coating based on a textile cloth base and a preparation method thereof. Background technique [0002] Heat-insulating coating is a functional coating that can effectively prevent heat conduction, reduce surface temperature, improve the working environment and reduce energy consumption, and is widely used in buildings, textiles, ship decks, aerospace military and other fields. For example, after the thermal insulation coating is applied to the tent, it can not only improve the comfort in the tent, but also reduce the cooling energy consumption in the tent. As people pay more attention to the quality of outdoor activities and leisure life, the heat insulation applied to indoor and outdoor textiles is particularly important, especially the heat insulation of military tents and outdoor tents.

Problems solved by technology

[0003] Nowadays, the development of thermal insulation coatings is mainly aimed at the construction industry, industrial equipment, etc. There are few reports on thermal insulation coatings applied to textiles. At present, the thermal insulation effect is mainly achieved by compounding a layer of low thermal conductivity film with the fabric base cloth, such as patent No. The Chinese patent of 201120180965.5 "A curtain fabric with thermal insulation effect" is characterized in that a PVC transparent film covering layer is compounded on the surface of the base fabric through heat treatment, and the heat insulation function is very limited; the patent number is 201620375957.9 Chinese patent " A kind of heat-insulating coating cloth ", it is characterized in that comprising base cloth, PU coating, ceramic fiber particle, heat-insulating filler, fire-retardant coating, film coating, base cloth surface is provided with PU coating, PU coating top Airgel thermal insulation filler containing ceramic fiber particles is set, and a flame-retardant coating is provided on the thermal insulation filler, and a film coating is provided on the upper surface of the flame-retardant coating. This patent only considers the heat conduction mode in heat transfer, and the reflective The radiation function is limited, and the relevant patents do not specifically express the heat insulation effect
