Description
Technical Field
The invention belongs to the field of chemical building materials, and particularly relates to a high-toughness, non-mildew and odor-removing true porcelain adhesive and a preparation method thereof.
Background
The traditional crack sealer is coated on the surface of the crack sealer, and the novel crack sealer does not need the crack sealer as a bottom layer and can be directly added into the gaps of the ceramic tiles after the ceramic tiles are bonded. The filling agent is suitable for filling gaps with the thickness of more than 2mm, is more convenient than the common filling agent in construction, and is an upgrading and updating product of the filling agent. The novel seam beautifying agent is a semi-fluid liquid prepared by finely mixing a high-tech novel polymer, a high-grade pigment and a special auxiliary agent, and is different from white cement and a color seam filling agent (dry powder cement material and low-grade pigment). The novel seam beautifying agent has luster, rich, natural and fine color, such as golden color, silver color, pearly color and the like; the white and black chromaticities are obviously higher than those of the white cement and the color gap filler, and a better integral effect is brought to the wall surface, so that the decoration property is greatly stronger than that of the white cement and the color gap filler. And after the ceramic tile is solidified, the surface is smooth like porcelain, can be scrubbed together with the ceramic tile, has the characteristics of permeation resistance and water resistance, and can realize that the real gap of the ceramic tile never becomes black.
The problems that gaps of ceramic tiles are changed from white to black and are extremely unsanitary and attractive are usually encountered in living rooms and kitchens and toilets of modern homes, bacteria are bred when the gaps of the ceramic tiles are changed to black, peculiar smell is generated, the health of human bodies is seriously harmed, and the bacteria are particularly obvious in summer. The difficult problem which puzzles the decoration industry for many years is overcome by the crack-beautifying agent, a series of problems caused by blackening of brick joints are solved, and the decoration grade is greatly improved. The seam beautifying agent has various colors, no water absorption, oil stain resistance, easy cleaning, no color change, wear resistance and high strength. Completely changes the phenomenon of black and mildew.
The main material of the seam beautifying agent is epoxy resin and epoxy curing agent, and the auxiliary materials are toner, fumed silica, auxiliary agent, titanium dioxide and the like. According to the material, the method can be divided into three types: the polyether modified crack sealer, the alicyclic amine modified crack sealer and the fatty amine modified crack sealer have the following advantages and disadvantages:
polyether modified crack beautifying agent: the main materials of the epoxy resin are the same, but the main material of the curing agent is modified by polyether amine as the main material.
The advantages are that: the product has the advantages of high gloss, good flexibility, slow curing speed, small smell, easy construction, easy cleaning and relatively low cost, and is a main seam beautifying material popular in the market at present.
The disadvantages are as follows: the hardness is not high, the strength is poor, the heat resistance is not good, the yellowing is easy to happen when the ultraviolet light is encountered, and in addition, the water absorption property of the polyether product is good, so the construction is not suitable when the water resistance or the humidity is high. The cured product has good flexibility but poor adhesion, so the material is not suitable for edge sealing of hotels, bathrooms and kitchens and bathrooms.
② alicyclic amine modified crack-beautifying agent
The advantages are that: the product has the advantages of flexibility, rigidity, excellent yellowing resistance, high strength after curing, strong adhesive force, certain acid and alkali resistance, and is very suitable for high-grade hotel decoration and home decoration. After the curing is completed, the temperature resistance is superior to that of the polyether modified seam beautifying material.
The disadvantages are as follows: because the main bodies of the raw materials are imported, the product cost is relatively high. But the waterproof performance is excellent, the product has higher requirement on storage, and particularly, the product is easy to react with carbon dioxide in the air to form waxing or atomizing phenomena in the production process, such as poor sealing or long-time exposure in the air.
③ fatty amine modified crack-beautifying agent
The advantages are that: the curing speed is high, the cured product has high hardness, strong adhesive force, good chemical corrosion resistance, low price of raw materials and low cost.
The disadvantages are as follows: poor yellowing resistance, poor water resistance, poor gloss of a cured product on a wet surface, water swelling, poor flexibility and insufficient durability.
At present, the crack beautifying agent has a plurality of products in the market, but compared with a plurality of advantages announced by production enterprises, the real porcelain cement really used by consumers has the defect of not being small. For example, the product has insufficient toughness, and after the product is used for a period of time, the product is often cracked under the action of reaction shrinkage stress and bonding tensile stress.
