Description

Waterproof and heat-insulating paint and its preparation method

Technical field

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

Background technique

In the current existing 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 is applied. Lay ceramic tiles on the cement. 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 due to the rainwater penetrating the structure of the building.

But 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 thermal insulation layer at the bottom will be partially exposed. After a period of sun and rain, the waterproof layer and thermal 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 internal 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, it is actually extremely difficult to inspect and find because the damaged area is covered by tiles.

Summary of the invention

technical problem

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 guaranteed that the water leakage problem can be completely solved, and if the entire waterproof layer and the heat-proof layer are completely removed After re-covering and applying it again, this method is obviously too expensive to maintain and not economical.

In view of this, how to eliminate the above-mentioned deficiencies is the technical difficulty that the inventor of the case intends to solve; yes, the inventor of the case is based on years of experience in the relevant industry, after years of painstaking research, trial improvements, Finally successfully completed the research and development of this case, and the invention was born to enhance the efficacy.
