Neutral mosaic back gum with high flexibility

Abstract

The invention relates to neutral mosaic back gum with high flexibility. The neutral mosaic back gum with high flexibility comprises redispersible emulsion powder, quartz sand, water reducing agents, a defoaming agent, lignocellulose, a mildewproof agent, cellulose ether, bentonite and sodium chloride and is a non-cement-based one-component dry powder product. The neutral mosaic back gum is used for sticking mosaics, can be used for solving the problems of oxidation of mosaics and insufficient bonding force caused by traditional cement bases, also has high flexibility, can be used on lightweight walls and vibrating parts, has the advantages of low possibility of deterioration and easiness in transport and storage compared with non-cement-based pasty or liquid products, can achieve construction under the condition of zero degree and has strong practicability.

Description

technical field [0001] The invention relates to an adhesive used for pasting mosaics, in particular to a high-flexibility neutral mosaic adhesive, which belongs to the technical field of bonding materials in the construction industry. Background technique [0002] Mosaic, also known as mosaic tile, is a kind of sheet-like architectural decorative material that can be spliced ​​into various patterns. It was originally made of small-sized tiles. It has been vigorously developed from the initial ceramic mosaic to stone mosaic, stone mosaic, glass (including hot-melt glass and crystal glass) mosaic, metal mosaic, wood mosaic, shell mosaic, leather mosaic, resin mosaic and so on. The product, because the mosaic is exquisite and small, the pattern is changeable, there are many combinations, it is full of personality, and it is deeply loved by people. Its application range also covers every corner of people's life, from home decoration bathroom walls, floors, swimming pools to buil...

AI Technical Summary

Problems solved by technology

However, with the development and application of mosaic technology, cement-based adhesives have gradually revealed their shortcomings: (1) Cement-based adhesives are rigid adhesive products, and they are used in areas with large vibrations or wood boards, splints, and gypsum boards. When light-weight walls such as cement fiberboards are used to paste mosaics, there are certain safety hazards, and the performance requirements of the products in the above environment cannot be met; (2) Calcium hydroxide will be produced during the hydration process of cement, and the hydration products are Strong alkaline, for glass mosaics such as gold foil, mirror surface, electroplating, and cold spray, because they have not been melted at high temperature, the color layer of the mosaic material and the glass layer are connected by glue. Oxidation turns black, thus losing the decorative effect. Therefore, when using cement or cement-based adhesives to lay glass mosaics, the strong alkali produced by cement hydration acts on the glass mosaic, which will not only affect the decorative effect, but also affect the life of the glass mosaic.

For example, CN 103214212 A discloses a paste-like tile adhesive and a preparation method thereof. The paste-like tile adhesive disclosed is a single-component, non-cement-based tile adhesive, and its components include quartz sand, fillers, Water retaining agents, emulsions, additives, and lignocellulose are designed to solve the problems that cement-based products are prone to in the actual process, and also solve the problems of short storage time and easy deterioration of paste-like tile adhesives during storage. They can be widely used Pasting of wall and floor tiles in living room, toilet and balcony

However, the transportation and application of paste or liquid non-cement-based adhesive products are often restricted by temperature, especially in winter in the north, where transportation and storage are often problematic in areas below zero degrees Celsius, and construction cannot be carried out.

[0005] There are also inorganic adhesives, but even if some inorganic adhesives can meet the requirements of mosaic paste, when used in areas with large vibrations or on the aforementioned light walls, their flexibility is poor, and the existence of safety hazards cannot be avoided.

[0006] At present, there is no one that is specially used for mosaic paste, which can properly solve the aforementioned problems such as the oxidation of mosaics caused by the use of traditional cement-based adhesives, and can also be used on light walls and vibrating parts. Applicable Broad range, highly flexible, neutral non-cementitious adhesive
