Problems solved by technology

However, many other shortcomings of cement mortar in the bonding of interior and exterior walls of buildings still cannot be solved; and because the bonding and caulking are divided into two processes, it is more complicated and time-consuming; Applying on a large area will not only waste 1 / 3~1 / 2 of the caulking material, but also easily pollute the surface of the building, increasing the labor and cost of cleaning

Abstract

The invention provides a kind of waterproof color caulking adhesive for building and its preparation method, comprising cement, quartz sand, water-based cellulose ether, lignin, pigment, vinyl acetate copolymer latex powder, organic carboxylic acid metal salt powder Mix evenly to prepare the building waterproof color caulking adhesive of the present invention. The adhesive of the present invention forms a highly waterproof surface during use, has the characteristics of waterproof, adhesive, beautiful, durable, and environmentally friendly, and integrates joint filling and bonding. It is a functional building material, and its price is comparable to that of cement. Modified materials are comparable. It is suitable for bonding and caulking of exterior wall tiles, floor tiles, interior wall tiles, stone and square tiles.

Description

technical field [0001] The invention relates to the field of building materials, and relates to a waterproof color caulking adhesive for construction with integrated functions of waterproofing, bonding and caulking and a preparation method thereof. Background technique [0002] At present, cement mortar is used to bond the inner and outer walls of buildings with magnetic sheets, tiles, cultural bricks, stones, etc., but the bonding strength is low, especially the initial bonding performance is relatively poor, and thick layer construction is usually used. There are many disadvantages, such as: easy to sag, easy to fall off, crack, etc. during construction, especially because the current building walls are stipulated to use lightweight bricks, hollow bricks, fly ash bricks, etc., the walls are very permeable, and cement mortar is not waterproof. Once water seeps through the gaps between the magnetic sheets or tiles, it will cause water seepage and leakage in the entire buildi...
