Embodiment 1

[0036] Taking the production of 500 grams of the product of the present invention as an example, the raw materials used and the proportioning thereof are:

[0037] Catalytic oil slurry: 350 grams, produced by Maoming Petrochemical

[0038] Rubber powder: 115 grams, recycled waste rubber powder produced by Lingzhong Composite Materials Company, fineness=60 mesh

[0039] Hard asphalt: 35 grams, recycled waste road asphalt produced by Road Recycling Company, penetration = 31

[0040] First heat the catalytic oil slurry to 120°C and then pour it into a high-speed shearing machine, and keep the temperature at 120°C. Divide the rubber powder into 3 parts, the first and second parts are 40 grams respectively, and the third part is 35 grams. First, slowly pour the first rubber powder into the high-speed shearing machine and carry out circular shearing together with the catalytic oil slurry. When the first After the first part of rubber powder is completely mixed with the catalytic o...

Abstract

The invention discloses a low-cost high-performance caulking adhesive. The caulking adhesive comprises, by mass, 50-79% of catalytic oil slurry, 16-40% of rubber powder and 5-10% of hard asphalt. Theinvention further discloses a preparation method of the caulking adhesive. The caulking adhesive takes the low-price catalytic oil slurry as a main raw material, the high-proportion rubber powder is added for shearing and mixing to form a high-performance cementing material, then a certain proportion of hard asphalt is added to adjust the hardness, volatile components in the cementing material arefurther removed through long-time ventilation and stirring oxidation, the high-temperature stability and the ageing resistance of the cementing material are improved, and then the low-cost high-performance caulking adhesive for engineering is prepared.

Description

technical field [0001] The invention relates to an engineering caulk, which belongs to the technical field of engineering materials, and also relates to a preparation method of the caulk. Background technique [0002] Traditional cement concrete pavement expansion joints, bridge deck joints and caulking filling materials for various construction engineering cracks are mainly made of ordinary petroleum asphalt, which has average performance but high production cost. According to statistics, my country uses nearly 10,000 tons of caulking materials for various types of engineering every year, and with the continuous construction and development of highway projects, bridge projects and other types of construction projects in China, the market for caulking The demand for materials will also increase. At present, in addition to directly using ordinary asphalt as caulking materials, many modified asphalt caulking materials have appeared in order to improve its various properties. ...
