Embodiment 1

[0011] First, heat the asphalt until it melts, then slowly add 50% of the asphalt mass of fly ash into the molten asphalt, stir evenly, then add 2% of the asphalt mass of calcium stearate into the mixture of molten asphalt and fly ash , high-speed stirring, the air can continuously enter the mixture to form stable microbubbles. Brush 3cm of this air-entrained mixture on the roof of the building that needs to be insulated. After the mixture is solidified, a stable waterproof and insulating layer can be formed, and its thermal conductivity is 0.17W / m2K.

Embodiment 2

[0013] First, heat the asphalt until it is melted, then slowly add 50% of the asphalt mass of fly ash into the molten asphalt, stir evenly, then add 3% of the asphalt mass of calcium stearate into the mixture of molten asphalt and fly ash , high-speed stirring, the air can continuously enter the mixture to form stable microbubbles. Brush 3cm of this air-entrained mixture on the roof of the building that needs to be insulated. After the mixture is solidified, a stable waterproof and insulating layer can be formed, and its thermal conductivity is 0.14W / m2K.

Embodiment 3

[0015] Firstly, heat the asphalt until it melts, then slowly add 50% of the asphalt mass of fly ash into the molten asphalt, stir evenly, then add 5% of the asphalt mass of calcium stearate into the mixture of molten asphalt and fly ash , high-speed stirring, the air can continuously enter the mixture to form stable microbubbles. Brush 3cm of this air-entrained mixture on the roof of the building that needs to be insulated. After the mixture is solidified, a stable waterproof and insulating layer can be formed, and its thermal conductivity is 0.11W / m2K.

Abstract

The invention relates to a manufacture method for modified pitch water proof heat keeping coating material that includes the following steps: heating the pitch until fusil; adding 50wt% fly ash into pitch, whisking to equal; adding 2-5% calcium stearate into the mixture, whisking in high speed to make air enter into the mixture to form micro air bubble; taking airbleeding to the mixture. The invention is easy to make and could be used in construction roofing.

Description

technical field [0001] The invention relates to a manufacturing method of architectural paint, in particular to a manufacturing method of modified asphalt waterproof and thermal insulation paint. Background technique [0002] There are many types of waterproof coatings for building roofs, but few have the function of heat preservation. In rural areas, due to the limitation of construction costs, the roofs of buildings are generally no longer heat-insulated. If a low-cost building waterproof coating with heat-insulation function is developed, it will be very meaningful for rural building energy saving and will have a great impact. market space. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiencies in the prior art, and provide a low-cost method for making building roof thermal insulation and waterproof coatings through continuous experimentation and improvement. The method uses asphalt and fly ash as main r...
