Non-cured rubber asphalt waterproof paint and preparation method thereof

Abstract

The invention discloses a non-cured rubber asphalt waterproof paint and a preparation method thereof. The preparation method comprises the following steps: 1) weighing a matrix asphalt, a softener, an elastic plastic body, an adhesion agent, a functional polymer, a stabilizing agent and a filling material; 2)injecting the matrix asphalt to a reaction vessel, heating the materials, stirring the materials, adding the softener, and stirring the materials; 3) adding the obtained mixture and the elastic plastic body in a colloid grinder, growing the materials, opening the colloid grinder, grinding the materials, and continuously growing the materials; 4) adding an adhesion agent and a functional polymer, continuously stirring the materials; 5) adding a filling material and stirring the materials; and 6) adding a stabilizing agent, and stirring the material. The paint has high heat resistance, good construction property, good thermostability, chemical stability and anti-ultraviolet aging capability, bond property is not influenced due to extraneous environment, the paint has construction property for a wet basic layer, can increase the interfacial affinity interaction with the wet basic layer, and construction quality and progress can be effectively guaranteed, and the paint is environmentally friendly.

Description

technical field [0001] The invention relates to a non-curing rubber asphalt waterproof coating and a preparation method thereof, belonging to the field of building waterproofing. [0002] technical background [0003] Humans have a long history of using asphalt for waterproofing, and asphalt waterproofing materials still occupy an important position. Common asphalt waterproofing products include polymer modified asphalt waterproofing membrane and modified asphalt coating, which have their own advantages and disadvantages in application range, construction conditions and waterproof effect. Among them, asphalt coatings mainly include solvent-based and water-emulsion-based, which are widely used in various waterproof projects, but there are three fatal problems in the process of use: long construction period, environmental safety and impermeability caused by volatile organic substances Poor sex. [0004] At present, the most widely used composite waterproof system of waterproo...

[0006] The adhesive layer material that can achieve the above-mentioned elastoplasticity is generally called non-curing asphalt waterproof coating, which can be melted by heating, can be sprayed and scraped, has excellent adhesion performance, can maintain a viscous state for a long time, has good creep properties, and can It adapts to the deformation of the base layer, cracks and maintains waterproof performance, so it has received extensive attention. At present, almost all waterproof enterprises at home and abroad have studied it, such as CN102031002A non-curing asphalt glue, CN102127367A rubberized asphalt non-curing waterproof coating and its preparation process, CN102086349A- A kind of non-curing waterproof glue with dual characteristics, CN102775956A, a kind of asphalt-based non-curing high-temperature resistant waterproof sealant and its preparation method, etc., these inventions all disclose corresponding invention formulas respectively, but the high viscosity under high temperature has always been difficult for each invention. The pain point of transcendence, although some patents have low viscosity at high temperature, but poor heat resistance and low bonding strength
