Problems solved by technology

[0003] There are many ultra-insulation coatings that have been developed, but most of them are opaque coatings used in extensive environments such as pipelines and exterior walls, while transparent ultra-insulation coatings are rare. Several transparent coatings have been published in China since 2007. Patent for super thermal insulation coating, but it either has the disadvantage of poor dispersion stability, or the process is complicated and the cost is high, and there is a lack of a transparent super thermal insulation coating with better performance suitable for large-scale promotion and application

[0036] Chloride acid 0.08%,

[0037] Zinc oxide 0.15%,

[0038] 325 mesh anti-sinking soil 25%. (Produced by Anhui Mingmei Mineral Chemical Co., Ltd.)

[0039] The preparation method is as follows:

[0040] 1) Grinding the solid matter in the raw material until its particle size is less than 4nm.

[0041] 2) Mix and stir epoxy resin, α-terpene resin, dimethyl mixed acid, and anti-settling powder for 5-7 minutes, then slowly add zinc oxide, stir well, add chlorobridge acid, stir for eight minutes, and then put it into a barrel, that is For material A.

[0042] 3) Mix and stir the epoxy resin curing agent and 2,4,6-tris(dimethy...

Embodiment 2

[0046] Take raw materials by weight fraction as follows:

[0047] Epoxy E-44 22%,

[0048] 2,4,6-tris(dimethylaminomethyl)phenol 0.8%,

[0049] T31 type epoxy resin curing agent 0.6%,

[0050] alpha terpene resin 0.07%,

[0055] The preparation method is the same as in Example 1, and the above-mentioned transparent thermal insulation coating is tested as follows: prepare five closed wooden boxes with only two open tops, fix a thermometer in the center of the wooden box, and cover the wooden box with a whole piece of glass One of the glass is coated with transparent thermal insulation paint, the other is not coated, and the interface is sealed. Initially, the readings of the thermometers in the two boxes are the same. Put the two wooden boxes covered with glass panels in direct sunlight, with the glass facing up so that sunlight can ...

Embodiment 3

[0057] Take raw materials by weight fraction as follows:

[0058] Epoxy E-44 40%,

[0059] 2,4,6-tris(dimethylaminomethyl)phenol 0.1%,

[0060] T31 type epoxy resin curing agent 0.09%,

Abstract

The invention discloses a transparent heat insulation coating. The transparent heat insulation coating comprises the following components in percentage by weight: 10%-40% of epoxy resin, 0.1%-2% of 2,4,6-tris-(dimethylaminomethyl) phenol, 0.05%-2% of expoxy resin curing agent, 0.01%-15% of alpha terpene resin, 40%-65% of mixed acid methyl ester, 0.01%-1% of chlorendic acid, 0.01%-1% of zinc oxide, and 15%-30% of anti-settling powder. The transparent heat insulation coating provided by the invention has high transparency and excellent heat resistance effect, is convenient and raid to construct, can be applied to glass, metal and surfaces of other materials and is particularly suitable for the heat insulation of automobile bodies. In addition, a productive technology of the transparent heat insulation coating is simple, is low in production cost and is beneficial to large-scale generalization and application.

Description

technical field [0001] The invention relates to a transparent thermal insulation paint and its preparation and application. Background technique [0002] Since the reform and opening up, under the background of continuous rapid economic growth and increasing environmental pressure, the Fifth Plenary Session of the 16th CPC Central Committee clearly proposed "building a resource-saving and environment-friendly society", and for the first time constructed resource-saving A modern and environment-friendly society is determined as a strategic task in the medium and long-term planning of national economic and social development. Under this background, the development of super thermal insulation coatings has become a research hotspot and has great practical significance. [0003] There are many ultra-insulation coatings that have been developed, but most of them are opaque coatings used in extensive environments such as pipelines and exterior walls, while transparent ultra-insulat...
