Special jointing agent for flexible sheet and preparation and construction method thereof

Abstract

The invention provides a special jointing agent for a flexible sheet and a preparation and construction method thereof.Thespecial jointing agent for the flexible sheetis prepared from the components in percentage by weight: 30%to 32% of amixing emulsion and 68%to 70% of natural color sand and / or sintering color sand, the mixing emulsion is prepared from 40%to 45% ofa pure acrylic emulsion, 15%to 20% of a silicone-acrylate emulsion, 0.4%to 0.5% of a coalescing agent, 0.4%to 0.5%of propylene glycol, 0.1%to 0.2% of a preservative, 20% to 25% of 2%ethyl-hydroxyethyl cellulose ether aqueous solution, 0.1%to 0.2%ofdefoamer, 0.4%to 0.6 of thickener,and 12% to 20% of water; the natural color sand has different particle sizes and different colors, and the sintering color sand is artificial sintering color sand with various colors formed through melting in high temperature, stirring, and evenly coating of pigment on the surface of the wear-resistant white sandat 600 to 1000 DEG C by using high-temperature resisting pigment and the wear-resistant white sand; and the special jointing agent for the flexible sheet has the characteristics of being cracking-resistance, whiskering-resistance, simple in jointing, and low in cost, and the defects of the prior art are overcome.

Description

technical field [0001] The invention relates to the technical field of painting, and more specifically, to a special pointing agent for flexible sheets, a preparation method and a pointing construction method of the special pointing agent for flexible sheets. Background technique [0002] At present, all kinds of exterior wall decoration materials emerge in endlessly. In the need of design style, most of the decoration materials need to leave a design separation in the construction of the exterior wall, and use jointing agent to carry out jointing treatment on the separation parts, in order to achieve beautiful appearance , waterproof and other effects. [0003] Up to now, the external wall pointing methods and the pointing agents used are mainly as follows: [0004] Pointing method 1: Coating construction pointing method [0005] Coatings (emulsion paints for exterior walls, solvent-based paints, metallic paints, sand wall-like texture paints, water-in-water colorful pain...

AI Technical Summary

Problems solved by technology

One is cement-based jointing agent, which is cheap but cannot overcome problems such as efflorescent cracking; the other is weather-resistant silica gel, which has excellent performance but is expensive

Both of them are not suitable for jointing of new building decoration materials——flexible sheets. It is necessary to develop a special jointing agent that can overcome the above defects and is suitable for flexible sheets.
