Problems solved by technology

However, because the modified material is reclaimed rubber, its technical performance is relatively unstable, its anti-ultraviolet performance is not ideal, and its tensile strength is not ideal, especially the properties such as tensile strength and tear strength after film formation are not ideal.
However, the traditional hot-boiled asphalt waterproof coating requires hot construction, which needs to be above 200 ° C, and is easy to bubble, brittle, often leaks, difficult to maintain, and pollutes the environment.

Abstract

The invention discloses a bentonite waterproof paint and a production method thereof. The paint is composed of the components of: 40-55 parts of mixed asphalt, 5-7 parts of nano-grade bentonite, 1-7 parts of a styrene-butadiene rubber solution, 0.2-0.7 parts of mica powder, 0.1-0.5 parts of dodecyl trimethyl ammonium bromide, and 40-55 parts of deionized water. The particle size of the nano-grade bentonite is 20-100mm. When the paint is used in construction under a temperature below -15 DEG C, the components are: mixed asphalt 35-55%, the nano-grade bentonite 6-20%, and diesel oil 34-50%. The paint is advantaged no toxicity, no odor, cold construction, high work efficiency, low cost, and good mechanical performances. The method is advantaged in no three-waste pollution during productions. The paint can be used in roofing plate calking, plate surface coating, old roofing repairing, underground water proofing and damp proofing, washroom leakage preventing, wood decay preventing, and road paving.

Description

technical field [0001] The invention relates to a chemical product, in particular to a bentonite waterproof coating and a production method thereof. Background technique [0002] House leakage has always been an old, big, and difficult problem in the construction industry. The main reason is the poor quality of waterproof materials. At present, there are three main types of high-tech waterproof coatings used at home and abroad: the first type is solvent-based, and its main disadvantages are high cost, poor safety, harmful to human body, flammable, polluting the environment, and not widely used; the second type is Water-emulsion polymer coatings are expensive and not ideal; the third type is elastic modified asphalt, which has good flexibility at low temperature but poor performance at high temperature. In order to find better substitutes, my country has started research on water-emulsion polymer waterproof coatings, and developed water-emulsion reclaimed rubber asphalt wate...
