Embodiment 1

[0022] A thermal insulation coating, prepared according to the following formula and steps:

[0023] 1. Put the selected nylon material with a fineness of 800 mesh into the stirring tank, add the formulated amount of sodium dodecylbenzenesulfonate and polyoxyethylene alkylated ether wetting agent, stir at 300r / min for 10min, and control the temperature at 40 At 60°C, modify the polymer material so that it can be wetted by water so that it can be well dispersed in water;

[0024] 2. Add the formula amount of deionized water into the stirring tank, add the formula amount of paint dispersant, paint defoamer, rutile titanium dioxide and filler under stirring at 800r / min, and stir for 20 minutes; put the dispersed material Grinding in a sand mill until the fineness is below 80 μm;

[0025] 3. Add the elastic emulsion into another stirring tank, add the material prepared in step 2 evenly under low-speed stirring, stir for 20 minutes, and the stirring speed does not exceed 300r / min;...

Embodiment 2

[0033] The difference between this embodiment and embodiment 1 is that the selected polymer material is epoxy resin with a fineness of 1200 mesh.

[0034] The reason why the present invention selects ultraviolet light-curable elastic emulsion is that the thermal insulation coating for exterior walls requires good elasticity, and no cracks appear on the wall body under the condition of heat expansion and contraction. It will be greatly reduced; the exterior wall paint requires a certain stain resistance when exposed to the atmosphere, so the emulsion is required to have a certain hardness on the surface during the film forming process, while the inside is elastic. can meet the above requirements. The thermal conductivity of the ultrafine macromolecular material used in the present invention should be low, and it needs to be modified, because the general macromolecular material is not easy to disperse in water, and the density is smaller than water, so when selecting the macromo...

Abstract

The invention discloses a heat insulation and heat preservation paint. The paint is characterized by comprising the following components in parts by weight: 185 parts of water, 80 parts of high polymer material of which heat conduction coefficient is 0.2 0.5W / m.K and fineness is 800-1200 meshes, 3 parts of sodium dodecyl benzene sulfonate, 3 parts of wetting agent, 5 parts of paint dispersant, 4 parts of paint defoaming agent, 6 parts of modified polysiloxane flatting agent, 170 parts of rutile type titanium dioxide powder, 10 parts of paint thickener, 80 parts of hollow glass beads of which average particle size is 70mu m, 30 parts of filler and 430 parts of ultraviolet cured elastic emulsion. The invention also discloses a production method of the paint. By adopting the method to produce the heat insulation and heat preservation paint, the technology is simple and has no three-waste discharge and the produced paint has good elasticity and the functions of heat insulation and heat preservation, is easy to construct, is fireproof and drop-proof and has long weather resistant time.

Description

technical field [0001] The invention relates to a heat-insulating and heat-insulating coating produced by using heat-insulating and heat-insulating materials, and also relates to a production method thereof, which belongs to the technical field of fine chemicals. Background technique [0002] Since the 1980s, the world's climate has become warmer and energy has become increasingly exhausted. Under the dual pressure of environmental protection and energy, the coatings industry is facing a major issue of developing new, high-efficiency thermal insulation coatings. [0003] Thermal insulation coatings are widely used in various buildings and some industrial fields, which are related to human life, energy saving, comprehensive utilization of resources, safe production and many other aspects. Only building insulation and air conditioning account for more than 20% of the total energy consumption of various countries. . [0004] Heat transfer is realized in three ways: convection,...
