example 1

[0018] According to the mass ratio of 1:25, mix barium carbonate and 10% acetic acid solution by mass fraction, heat in a water bath at 45°C for 1 hour, filter the filtrate to prepare solution A, and then mix tetrabutyl titanate with a mass ratio of 1:15 Mix the ester with absolute ethanol, stir and mix with magnetic force at 450r / min for 25min to prepare solution B, then slowly add solution A dropwise to solution B under the condition of heating in a water bath at 45°C at a volume ratio of 1:5, and control The dropping rate was 15min. After the dropping was completed, the mixed gel solution was left to defoam; the mixed gel solution was placed in a spray gun, and evenly sprayed onto the surface of a clean glass plate under 3MPa, and the spray thickness was controlled to be 0.3mm, stand and solidify at room temperature for 3 hours, then dry at 120°C for 25 minutes, stand and cool to room temperature to prepare a sprayed film, crush the sprayed film and pass through a 100-mesh s...

Abstract

The invention relates to a thermal insulation coating for a barrier fabric and belongs to the technical field of preparation of coatings. The thermal insulation coating is characterized in that a flaky material is used as a substrate and is loaded with a deposited tantalum oxide material; the deposited tantalum oxide material uniformly coats a flaky substrate-shaped lens to form filler particles with high reflection strength; the filler particles have excellent reflecting properties for visible light and near-infrared light, so that the heat absorption property of textiles is effectively reduced, and a heat insulating protection effect is realized; and moreover, tantalum oxide formed by surface deposition and calcination compactly coats modified filler doped in the coating prepared by the invention and has excellent stable performance, so that the corrosion is effectively prevented in the daily use process of the coating, and the thermal insulation coating has high stability and using persistence.

Description

technical field [0001] The invention relates to a heat-insulating paint for heat-insulating fabrics, belonging to the technical field of paint preparation. Background technique [0002] Heat-insulating coated fabric is to coat a layer of heat-insulating coating on the fabric, which can reduce the internal temperature of the fabric covering by blocking, reflecting or radiating solar energy, and can reduce energy consumption. It has a good application prospect in the textile industry. Textile thermal insulation coatings were originally used in fabrics worn by military personnel to eliminate or reduce the difference in infrared reflection characteristics between the fabric and the background by reflecting, blocking, and radiating infrared radiation to achieve infrared camouflage for military personnel. Then it was applied in the civilian field. According to the way of inhibiting infrared heat radiation, the thermal insulation coating for fabrics can be divided into barrier the...
