Description

Waterproof and heat-insulating paint and its preparation method

The invention relates to a paint for buildings, especially a paint with waterproof and heat insulation functions.

In the currently known building structure, in order to prevent the intrusion of water vapor on the wall (especially the attic floor), a waterproof layer is usually applied to the plane first, then foam cement is applied to the waterproof layer, and finally the foam cement is laid. Tiles. If you want to have the function of heat insulation, an additional layer of heat insulation layer will be applied after the waterproof layer is applied, and then foam cement and tiles will be applied in sequence. In this way, it is possible to reduce the excessive temperature inside the building caused by the sun, and the internal water leakage caused by the rainwater penetrating the structure of the building.

However, the traditional waterproof building structure has its shortcomings. When the outer tiles are broken due to earthquakes or expansion due to the sun, the waterproof layer or heat insulation layer at the bottom will be partially exposed. After a period of sun and rain, the waterproof layer and heat insulation layer will become It may be damaged and lose its original function. Damage to the thermal insulation layer will reduce the thermal insulation efficiency of the building structure, and more seriously, if the waterproof layer is partially damaged, water vapor will penetrate into the building structure at the damaged location. Taking the roof of a general building as an example, the failure of the waterproof layer is particularly likely to occur at the corners. When the waterproof layer is partially damaged and water seepage occurs, water will leak along the wall structure to the lower floors, resulting in the inner walls of the lower floors. Water leaks or stains on the surface. Even if you want to find the location of the damaged waterproof layer to repair it, the damaged area is actually very difficult to inspect and find because of the covered tiles.

In the case that it is difficult to confirm the damaged point of the waterproof layer, if the waterproof layer and heat-proof layer are re-applied in a small area, it will not be able to completely solve the water leakage problem. If the entire waterproof layer and heat-proof layer are completely removed, Re-covering and applying this method is obviously too expensive to maintain and not in line with economic benefits.

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventor of this case wants to solve; yes, the inventor of this case is based on years of experience in the relevant industry, after years of painstaking research, trial improvements, and finally Successfully researched and developed this case and gave birth to the present invention to improve its efficacy.

In view of the above shortcomings, the waterproof and thermal insulation coating of the present invention includes: a white cement powder; a bone powder, which is sand powder or stone powder; and at least one polymer powder, the white cement powder, the bone powder, and The high molecular polymer powder is mixed, and a predetermined proportion of water is added during use to form a slurry. The characteristics of the present invention are: non-toxic, strong attached water, long-lasting, acid, alkali, salt, and heat resistance, and Rust, and can also be used on electronic equipment.

In order to facilitate the description of the content of the present invention and the effects that can be achieved, specific examples are listed in conjunction with the figure. Please refer to the first figure. The waterproof and heat-insulating coating 1 of the present invention includes: a white cement powder 10; a bone meal 20 , Which is sand powder or stone powder; and at least one polymer powder 30. In this embodiment, the polymer powder 30 is composed of polyvinyl chloride ethanol, PVA and gypsum powder, and the white cement powder 10, The bone powder 20 and the high molecular polymer powder 30 are mixed, and a predetermined proportion of water is added during use to form a slurry, wherein the white cement powder 10, the bone powder 20 and the high powder polymer powder 30 are Rice grains.

The waterproof and heat-insulating coating 1 of the present invention further includes surfactants, dispersants, waterproofing agents, expansion agents, EVA, PVA, re-dissolvable resin powder, acrylic powder, emu and mica.

The waterproof and heat-insulating paint 1 of the present invention can be coated or sprayed on buildings, exterior walls, roofs, floors, tile gaps, oil tanks, cement tanks and embankments, and can be used on wood, metal and electronic materials. After the thermal paint 1 dries, the high molecular polymer will form a protective film, so it has the effects of waterproofing, repairing leaking walls and insulating.

Please refer to the second figure, the method for preparing the waterproof and heat-insulating coating of the present invention includes the following steps:

One-time grinding A: Grind the plural bone materials into bone meal 20;

Mix B: Add a white cement powder 10 and at least one polymer powder 30 to the bone powder 20;

Secondary grinding C: Grind the bone powder 20, the white cement powder 10 and the polymer powder 30 at the same time, so that the bone powder 20, the white cement powder 10 and the polymer powder 30 form nano-level powders ；

Package D: The bone powder 20, the white cement powder 10 and the polymer powder 30 after the second grinding of C are sealed and packaged.

This type is packaged and sold in a powder state. The user adds water to make it into a slurry. Please refer to the third figure. Therefore, the manufacturing method also includes a blending E step: the bone meal after the second grinding C 20. The white cement powder 10 and the polymer powder 30 are mixed with a predetermined ratio of water to form a slurry, which can be used after being opened by the user.

In other words, the manufacturing method of the present invention includes two types of dry type and slurry type, which are available for users to purchase.

Please refer to Figure 4, which is another embodiment of the present invention. In this embodiment, the slurry is coated or sprayed on at least one surface of a substrate 40 or the substrate 40 is immersed in the slurry to make the slurry Penetrate into the substrate 40. The substrate 40 is in the form of a plate or a film. The material of the substrate 40 includes cement, wood, printed circuit board, plastic, metal or a material with water absorption, after coating or soaking The substrate 40 of the slurry is provided for bonding or coating on an article including buildings, electronic components, electronic devices, and mechanical equipment.
