Problems solved by technology

[0003] In my country, the modified bitumen waterproof material is generally based on waterproof membranes, and most of them use hemp silk or glass fiber reinforcement to increase the tensile strength, which will greatly reduce the elongation of the material. At the same time, the membrane and the base layer Adhesion has always been a big problem in construction
Although asphalt has better adhesion than waterproof membranes, it is generally not applied to the surface of basic structures such as roofs due to the blackness of asphalt

Embodiment 1

[0035] Component A: First, add 3% of the imported Shell bright-colored asphalt (Shell decolorized asphalt) to aromatic oil, 10% of C9 petroleum resin, heat and stir at 150-160°C, put 3% iron oxide red into the asphalt, and stir evenly. Made into colored asphalt for later use. Pump the prepared colored asphalt into the asphalt tank through a special asphalt pump and heat it to 160°C~180°C, put in 2% SBS rubber, stir at 100r / min for 2 hours, and then grind it through a colloid mill to prepare the polymer modified asphalt material Stir for 2 hours to soak, set aside. Pump hot water at 60°C into the soap tank, add anionic emulsifier (tal oil or sulfonated tall oil soap or sulfosuccinic acid) 1% and AEO-9 stabilizer 0.05%, and adjust the pH with NaOH Value to 11 to make soap. The prepared polymer modified colored asphalt and soap solution are simultaneously passed through a high-speed shearing machine to make a modified emulsified asphalt emulsion with a mass concentration of abo...

Embodiment 2

[0038] Component A: First, heat and stir 11% aromatic oil, 10% C5 petroleum resin, and 10% C9 petroleum resin at 150-160°C, add 3% chrome green into it, stir well, and set aside. Pump hot water at 60°C into the soap tank, add anionic emulsifier (sodium abietate or sulfonated rosin) 1% and AEO-9 stabilizer 0.05%, and adjust the pH value to 11 with NaOH to make soap . The prepared polymer modified colored asphalt and soap solution are simultaneously passed through a high-speed shearing machine to make a modified emulsified asphalt emulsion with a mass concentration of about 60%. Add 30% neoprene latex to the emulsion, and then add 0.4% The anti-ultraviolet agent UV477 and 1% antioxidant 55 should be stirred slowly to disperse evenly during the feeding process. After the feeding is completed, keep stirring for 30 minutes, then stop stirring, add a small amount of defoamer and stand still for 30 minutes After defoaming treatment, the finished product is packed into barrels.

Abstract

The invention belongs to the color polymer modified emulsion asphalt-base waterproof paint and a preparation method thereof. The color polymer modified emulsion asphalt-base waterproof paint is prepared by adopting multiple synthesis macromolecular polymers such as high-concentration ultrafine suspension micro-emulsion anion modified color emulsified asphalt, SBS (Styrene Butadiene Styrene) rubber, neoprene, macromolecular resin, epoxy resin and the like and multiple functional assistants such as the plasticizer as raw materials and by utilizing a special production process. After the color polymer modified emulsion asphalt-base waterproof paint forms a film, the color is bright, no brittle rupture exists at the low temperature of minus 30DEG C, no flowing exists at the high temperature of 120DEG C, the resilient return rate reaches 90 percent, the color polymer modified emulsion asphalt-base waterproof paint can be stably stored for more than 2 years, and the service life can reach 50 years.

Description

technical field [0001] The invention belongs to the technical field of waterproof building materials, in particular to a color polymer modified water-emulsion type asphalt-based waterproof paint and a preparation method thereof. Background technique [0002] As a traditional waterproof material, asphalt has good hydrophobicity, impermeability, plasticity and adhesion, and is a cheap building waterproof material commonly used at home and abroad. But it has defects such as low temperature embrittlement, high temperature flow, poor elasticity and poor aging resistance. If it is reasonably modified by selecting suitable materials, it can achieve the effect of enhancing strengths and avoiding weaknesses. [0003] In my country, the modified bitumen waterproof material is generally based on waterproof membranes, and most of them use hemp silk or glass fiber reinforcement to increase the tensile strength, which will greatly reduce the elongation of the material. At the same time, ...
