Abstract

The invention provides a manufacturing method of a vehicle glass thermal-insulation paint, which comprises the following steps: (1) preparing a nano ATO (antimony tin oxide) slurry; (2) preparing a nano thermal-insulation paint; and (3) coating a film on glass. The thermal-insulation material prepared from the ATO nano material is glittering and translucent, and has the advantages of excellent water resistance, higher surface hardness and superhigh adhesion; the stabilizing agent adopted in the technique is a composite lead salt stabilizing agent; the leveling agent adopts acrylic acid; the defoaming agent adopts organosiloxane; the thickener adopts methyl cellulose; and thus, the thermal-insulation paint is free of benzene, ketone, TDI (toluene diisocyanate) and other harmful substances, and is green and environment-friendly. The thermal-insulation paint adopts a rotary coating process, and thus, is uniformly covered on the glass surface; and the rotary coating process has the advantages of favorable transparency and low paint consumption, and can well control the film thickness. The thermal-insulation paint has the advantages of favorable light transmittance, favorable thermal-insulation effect and small sheltering coefficient, and has broad market prospects and higher popularization value.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to a method for manufacturing a heat-insulating paint for automobile glass. Background technique [0002] Traditionally, heat insulation film, heat reflective film and LOW-E glass are used to solve the problem of glass heat insulation. However, the poor light transmission and the price of several hundred yuan per square meter make it difficult for the public to accept. The market urgently needs inexpensive and high-quality upgraded products. Nano-transparent heat-insulating coatings are not only in the leading position in the world in terms of product quality and technical content, but also because of the use of the world's first and most advanced bonding technology and products as the carrier of nano-materials, the manufacturing cost is greatly reduced. Nano-transparent heat-insulating coatings The price has unparalleled high cost performance, and its terminal price is far...
