Problems solved by technology

However, none of the above-mentioned thermal insulation materials can solve the problem of thermal insulation of glass, that is, it must not only meet certain lighting requirements, but also be capable of thermal insulation.
The current method is to use insulating glass, but the cost of insulating glass is too high, so it cannot be widely used

Embodiment 1

[0017] Example 1. First make 12kg of yttrium oxide into nanoscale, then put it into the ultrasonic disperser together with 0.36kg of organic silicon coupling agent and 12kg of butyl acetate solvent, and disperse for 1-1.5 hours before use;

[0018] Put 37kg of fluorocarbon resin, 31.90kg of butyl acetate, and 16.00kg of xylene into a high-speed disperser, disperse at a slow speed (400-500 rpm) for 10 minutes, and then mix the above-mentioned treated nano-yttrium oxide and polyether Add 0.7kg of modified silicone, 0.4kg of silicone modified polysiloxane, and 2.0kg of silane coupling agent to a high-speed disperser for high-speed dispersion (1000-1500 rpm) for 30 minutes. After the dispersed material is ultrasonically treated for 1.5-2 hours, the appearance is transparent, and the transparency reaches 80% after detection, and the varnish of the present invention is obtained.

Embodiment 2

[0019] Example 2. First make 12kg of vanadium oxide into nano-scale, and then put it into the ultrasonic disperser together with 0.36kg of organic silicon coupling agent and 12kg of butyl acetate solvent, and disperse for 1-1.5 hours before use;

[0020] Put 40kg of polyurethane resin, 28.15kg of butyl acetate, and 14.00kg of xylene into a high-speed disperser, disperse at a slow speed (400-500 rpm) for 10 minutes, and then modify the above-mentioned nano vanadium oxide and acrylic acid Add 0.90 kg of fluorocarbon, 0.45 kg of fluorine-modified organosiloxane, and 3.5 kg of silane coupling agent to a high-speed disperser for high-speed dispersion (1000-1500 rpm) for 30 minutes. After the dispersed material is ultrasonically treated for 1.5-2 hours, the appearance is transparent, and the transparency reaches 80% after testing, and the varnish of the present invention is obtained.

Abstract

The invention relates to a solar heat- reflective insulating varnish, belonging to coating technology field. When it is coated on the surface of glass, it can insulate heat and maintain glass transparency. The invention aslo provides the preparation method. The comprised raw material and proportion by weight are as follows: film forming matter 35-45, inorganic oxidant 10- 15, levelling agent 0.5- 1, defoaming agent 0.3- 0.5, silane coupling agent 1- 5, and mixing solvent 33.5- 53.2. The varnish is characterized by heat resistance, water resistance, acid and alkali resistance, high reflecting solar heat, good light transmission rate, low cost, energy- saving, and suitability to be used for building galss, car glass, solar house heating, incandescent lamp lighting and refrigerator glass. The preparation process and device is easy and simple and is suitable for industrial production.

Description

technical field [0001] The invention relates to a solar heat reflecting heat insulating varnish and a production method thereof. Background technique [0002] Where there is a temperature difference, there is heat transfer. For people's living environment, the indoor temperature is higher than the outdoor in winter, and the heat will be transferred to the outside through the outer structure of the house, resulting in a decrease in room temperature and heat loss. Summer is the opposite of winter. In order to save energy and improve the living environment, buildings should have certain thermal insulation properties, which are usually achieved through good thermal insulation materials. At present, commonly used thermal insulation materials are: fibrous thermal insulation materials made of glass, mineral wool, asbestos or plant fibers, etc., loose granular thermal insulation materials made of expanded vermiculite or expanded perlite, etc. Porous insulation materials made of m...
