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 following components: 45-50 parts of softener, 8-13 parts of styrene-butadiene rubber, 5-9 parts of powdered styrene-butadiene rubber, and 3-6 parts of polypropylene particles parts, the first modifier is 5-9 parts, the second modifier is 15-20 parts, and the filler is 19-24 parts;

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

Abstract

The invention discloses a formula of a non asphalt-based non-cured coating and a preparation process of the non asphalt-based non-cured coating, and relates to an improvement on a waterproof coating, in particular to a production formula and process of the non asphalt-based non-cured coating. The formula is prepared from the following materials: 45 to 50 parts of a softening agent, 8 to 13 parts of butadiene styrene rubber, 5 to 9 parts of powdered butadiene styrene rubber, 3 to 6 parts of polypropylene particles, 5 to 9 parts of a first modifier, 15 to 20 parts of a second modifier and 19 to 24 parts of a filler. As a waterproof coating, the non asphalt-based non-cured coating is not cured when in long-term contact with air and always keeps the characteristic of sticky property; without an asphalt component, the coating has the characteristics of durability, corrosion resistance, nontoxicity, odorlessness and zero pollution.

Description

technical field [0001] The invention relates to the improvement of waterproof coatings, in particular to a production formula and process of a non-asphalt-based non-curing coating. Background technique [0002] At present, most of the waterproof curing coatings on the market use asphalt-based curing coatings, but the anti-aging ability of asphalt-based coatings is very weak, and a large number of cracks will occur after many years of completion. [0003] At present, 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 additives have the characteristics of extracting carbon black, natural rubber, SBS, anti- It has the function of oxidizing agent, and plays the role of special catalyst in the production process, which can form a stable chemical combination between asphalt and various macromolecules. However, the non-c...
