Description

Thermal insulation heat-saving energy-saving waterproof paste and preparation method thereof

The invention relates to a heat-insulating, energy-saving and waterproof paste and a preparation method thereof, and belongs to the technical field of building materials. The product is particularly suitable for use as inner and outer walls, roofs, and basements as heat-insulating, energy-saving and waterproof materials. Background technique

In the construction industry, the research, development, production, and application of thermal insulation, energy saving, and waterproof materials such as interior and exterior walls, roofs, and basements have attracted widespread attention. The material also needs to have the characteristics of anti-aging, anti-corrosion, safety, no pollution to the environment, etc. It is a comprehensive technical issue involving economic and social benefits. Among the existing coating heat-insulating, heat-insulating, energy-saving and waterproof materials, some can be heat-insulating, energy-saving, but not waterproof, and some are water-resistant, but not heat-insulating, energy-saving. Especially for external wall materials, there is a lack of excellent materials for effective thermal insulation, energy conservation and waterproofing. This is because, compared with internal walls, external walls are in a constantly changing environment, that is, hot, severe cold, wind, rain, Under the conditions of sunlight and night dew, it is difficult to keep the wall material's heat insulation, energy saving, and waterproof effect for a long time, to ensure that it does not crack, fall off, pollution-free to the environment, and hidden dangers of personal safety. . Therefore, it is not difficult to understand that there are some disadvantages in the existing technology. Addressing one of these shortcomings is a major advance in technology. For example, the patent application number is 96120603.9, and the name is a waterproof and heat-preservation coating, in which glass fiber is used, which has a good thermal insulation effect. However, during the production process and as a wall in the weathering process, glass fiber The respiratory system is inevitable a hazard. In this patent application technology and other similar technologies, perlite is used, but because latex participates in mixing, after the latex absorbs the latex, the thermal insulation effect is greatly affected. In addition, if the patent application number is 9512600.8, the name is thermal insulation waterproof paste and its production process, and its specification clearly targets the thermal insulation and waterproofing of interior walls and roofs, which solves the shortcomings of linoleum and thermal insulation ballast, but some still Disadvantages. For example, the latex used has poor adhesion, is easy to fall off, and has poor aging resistance, acid and alkali resistance, and the cellulose derivative used is still insufficient in terms of crack prevention. Summary of the invention

The purpose of the present invention is to overcome the shortcomings of the prior art and provide an anti-aging, acid and alkali resistance, Corrosion resistance, strong adhesion, no falling off, no cracking, safety, pollution-free heat insulation, heat preservation, energy saving and waterproofing, good overall effect, low environmental impact during construction, short heat preservation, heat preservation, energy saving and waterproofing paste; preparation method and process The steps are simple, stable, easy to operate and easy to ensure product quality.
