Problems solved by technology

However, the non-curing rubber asphalt waterproof coating has the following disadvantages: one is that the formula system contains a large amount of asphalt, and a large amount of asphalt fume will be discharged during the production process, which will be volatilized together with the fume during high temperature treatment, causing a certain degree of damage to the human body
Second, if the non-curing rubber asphalt waterproof coating is used as a waterproof material and soaked in a water environment for a long time, the harmful substances in the asphalt --- heavy metal salts will migrate out and dissolve in water, causing groundwater pollution

Embodiment Construction

[0010] The technical solution adopted in this specific embodiment is: it is prepared from the materials of the following components: 40-45 parts of softener, 3-8 parts of styrene-butadiene rubber, 1-5 parts of powdered styrene-butadiene rubber, 1-3 parts of polypropylene particles Parts, 1-5 parts of the first modifier, 10-15 parts of the second modifier, 14-19 parts of the filler;

[0011] The production process steps of the present invention are as follows: 1. Add the softening agent required in quantity, and continue to heat up to 200° C.; 2. Add styrene-butadiene rubber when the temperature reaches 200° C., and heat up the polypropylene particles to 210° C.-220° C. and continue stirring for 2 hours; 3. When the temperature reaches 230°C, add the first modifier and the second modifier in four batches, and the interval time should not be less than 30 minutes. Keep the temperature at 230°C-240°C and continue stirring for 5 hours; 4. Finally, add the filler in three batches Af...

Abstract

The invention provides a production formula and process for non-pitch-based non-curing coating, relates to waterproof coating improvement and particularly relates to a production formula and process for non-pitch-based non-curing coating. The production process includes steps of (1) adding a required amount of a softener, and continuously raising the temperature to 200 DEG C; (2) adding styrene-butadiene rubber and polypropylene particles when the temperature reaches 200 DEG C, raising the temperature to 210-220 DGE C, and continuously stirring the mixture for 2 h; (3) adding a first modifier and a second modifier in four batches when the temperature reaches 230 DEG C, with interval time being not less than 30 min, maintaining the temperature at 230-240 DGE C, and continuously stirring the mixture for 5 h; and (4) adding a filler in three batches, stirring the mixture for 1 h at a maintained temperature that is 190 DGE C after addition is finished, fully stirring the mixture, then cooling the mixture to 170 DEG C, and filling a tank with the mixture. The coating which is adopted as waterproof coating has characteristics of no curing after long-time contact with air, and capability of always maintaining sticky colloid. As the coating is free of pitch, the coating is characterized by being durable, corrosion resistant, nontoxic, odor-free and pollution-free.

Description

technical field [0001] The invention relates to the improvement of waterproof coatings, in particular to a production formula and process of non-asphalt-based non-curing coatings. Background technique [0002] Most of the waterproof cured coatings on the market currently use asphalt-based cured coatings, but the asphalt-based anti-aging ability is very weak, and a large number of cracks will occur after many years of completion. [0003] There are also some non-asphalt-based non-curing coatings on the market. The main raw materials used in these non-curing rubber asphalt waterproof coatings are waste tire powder, asphalt and special additives. The function of the oxidant, and the role of a special catalyst in the production process, can form a stable chemical combination between asphalt and various polymers. However, the non-curing rubber asphalt waterproof coating has the following disadvantages: one is that the formula system contains a large amount of asphalt, and a larg...
