Problems solved by technology

[0002] As one of the commonly used materials in the field of infrastructure and construction, waterproof coatings have mixed quality. The current waterproof coatings are generally poor in high temperature resistance. In summer, waterproof coatings are easy to melt and age, and in winter, they are easy to crack. This makes waterproof coatings adapt to Poor performance, short service life and poor ductility after molding, resulting in the need to re-use waterproof coatings for waterproofing every few years, thereby invisibly increasing cost and labor input

preparation example Construction

[0029] This embodiment also provides a preparation method for preparing the above-mentioned waterproof coating, which specifically includes the following steps, step 1, weighing the grease, thermoplastic elastomer, calcium powder, modifier and asphalt according to the above weight percentages for subsequent use;

[0030] Step 2, melt the asphalt weighed in step 1 at a temperature of 150-200°C, and add the oil, thermoplastic elastomer, calcium powder and modifier weighed in step 1 in sequence, and then keep stirring for 2-3 hours , and the mixture is circularly ground during the stirring process to obtain a molten liquid;

[0031] Step 3, cooling the molten liquid obtained in step 2 to 110-140°C, and then subpackaging to obtain the finished product.

[0032] This embodiment also provides an application of the above-mentioned waterproof coating in the preparation of a waterproof coiled material, which can make the waterproof coiled material also have a higher softening point, hi...

Embodiment 1

[0035] This embodiment provides a waterproof coating, which is composed of the following raw materials according to weight percentage, 18% of grease, 12% of thermoplastic elastomer, 12% of calcium powder, 1% of modifier and asphalt as the balance. Wherein, the grease is a mixture of aromatic oil, engine oil and base oil, and the ratio of aromatic oil, engine oil and base oil is 1:1:1; the asphalt is a mixture of 100# asphalt and 70# asphalt, wherein, 100# The amount ratio of # asphalt and 70# asphalt is 1:1 (mass ratio); the thermoplastic elastomer is SBS, SIS and SBR, and the amount ratio of SBS, SIS and SBR is 1:1:1 (mass ratio); The calcium powder is a mixture of light calcium powder and heavy calcium powder, and the dosage ratio of light calcium powder and heavy calcium powder is 1:1 (mass ratio); the modifier is asbestos fiber.

[0036] Its preparation method is as follows: Step 1, take grease, thermoplastic elastomer, calcium powder, modifier and asphalt according to the...

Embodiment 2

[0040] With embodiment 1, its difference is that described waterproof coating is made up of following raw material according to weight percentage, grease 22%, thermoplastic elastomer 17%, calcium powder 17%, modifier 3% and balance are asphalt. Wherein, the grease is a mixture of engine oil and base oil, and the amount ratio of engine oil and base oil is 1:1 (mass ratio); the asphalt is a mixture of 100# asphalt and 70# asphalt, wherein, 100# asphalt and 70# asphalt #The consumption ratio of pitch is 2:1 (mass ratio); The thermoplastic elastomer is SIS and SBR, and the consumption ratio of SIS and SBR is 1:1 (mass ratio); Described calcium powder is light calcium calcium powder and A mixture of heavy calcium calcium powder, and the dosage ratio of light calcium powder and heavy calcium powder is 2:1 (mass ratio); the modifier is asbestos fiber.

[0041] Its preparation method is as follows: Step 1, take grease, thermoplastic elastomer, calcium powder, modifier and asphalt acco...

Abstract

The invention discloses a waterproof coating, and a preparation method and application thereof, belonging to the field of chemical coatings. The waterproof coating is composed of the following raw materials by weight: 18-22% of grease, 12-17% of thermoplastic elastomer, 12-17% of calcium powder and 1-3% of a modifier, with the balance being asphalt. According to the invention, the thermoplastic elastomer, the modifier, the calcium powder and the grease are added for modification of asphalt, so the softening point and viscosity of the asphalt are improved, the low-temperature stability of the asphalt is enhanced, and the service life of the waterproof coating is prolonged.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to a waterproof coating and its preparation method and application. Background technique [0002] As one of the commonly used materials in the field of infrastructure and construction, waterproof coatings have mixed quality. The current waterproof coatings are generally poor in high temperature resistance. In summer, waterproof coatings are easy to melt and age, and in winter, they are easy to crack. This makes waterproof coatings adapt to Poor performance, short service life and poor ductility after molding, resulting in the need to re-use waterproof coatings for waterproofing every few years, thereby invisibly increasing cost and labor input. Contents of the invention [0003] In order to solve the above technical problems, one of the objectives of the present invention is to provide a waterproof coating with good temperature resistance, good ductility and long service life. ...
