Pure acrylic-acid elastic environment-friendly waterproof paint

Abstract

The invention relates to an acrylic-acid paint, particularly a pure acrylic-acid elastic environment-friendly waterproof paint which is prepared by blending the following components in parts by weight: 85-108 parts of acrylic acid emulsion, 4.5-23 parts of thickening agent, 0.017-0.04 part of activating agent, 0.23-1.7 parts of coupling agent and 0.09-0.23 part of defoaming agent. The waterproof paint has the characteristics of high elasticity, high strength, high extensibility and the like in rubber, has excellent functions of weather resistance and ultraviolet resistance, has wide climate application range (-20+ / -80 DEG C), and can be used for construction on a moist basal plane. Since the extensibility is up to higher than 380%, the waterproof paint does not deform or run when being used for sealing cracks of more than 10-30mm. The waterproof paint can be used for crack leakage maintenance of mosaic, ceramic tiles, glass curtain walls, external walls and concrete walls, and peripheral joint filling and integral painting of color steel tile roofing and door / window partitions.

Description

[technical field] [0001] The invention relates to an acrylic paint, in particular to a pure acrylic elastic, environment-friendly and waterproof paint. [Background technique] [0002] The pure acrylic waterproof coating in the prior art cannot seal cracks with a width of 1mm to 10mm during construction, and the coating cannot reach a thickness of 1mm-1.5mm within 96 hours. If a large area of ​​various types of exterior walls is painted twice (ordinary construction process), the color will be transparent within one month after construction, but after 2-7 months of exposure time, the coating will turn black and sticky, which will affect the building. cleanliness and beauty. The coating film has strong water absorption, and it will become white when it absorbs water in mildewy weather, or even blister and fall off. The design thickness cannot be reached during construction, and it does not have excellent elongation at break and tensile strength. In addition to being used for...

Problems solved by technology

The design thickness cannot be reached during construction, and it does not have excellent elongation at break and tensile strength

In addition to being used for general waterproofing of exterior walls and walls, it cannot meet the joints between various door and window frames and walls or the 45° angle joints of ceramic tile exterior walls, the joints of steel structure color steel tiles or glass curtain walls , the need for waterproofing of sun sheds, etc.
