Problems solved by technology

[0003] However, there is currently no adhesive specifically for seamless bonding of stone on the market. Generally, ordinary marble glue or stone pointing glue is used instead, but ordinary marble glue and stone pointing glue can seamlessly bond stone. There are some disadvantages
[0004] Referring to the patent CN1313556C "reinforced silica transparent marble glue", the disadvantages of ordinary marble glue used for seamless bonding are: ①. The interface of seamless bonding of stone is very small, almost "linear bonding", so for The adhesive strength requirement after curing of the colloid is very high (the compressive shear strength is not less than 20MPa), while the strength of ordinary marble glue after curing cannot meet the strength requirement of seamless bonding of stone materials, and it is a paste, and the product has poor infiltration and permeability. Well, cause it is easy to fall off after bonding
②. Ordinary marble glue has poor weather resistance and ultraviolet light resistance. After curing, the color will change with time, which will cause color difference between the bonding joint and the stone, which will affect the appearance
③. Ordinary marble glue does not have high requirements on the fineness of the colloid. After using it to bond stone materials, the bonding marks are more obvious, and the seamless effect cannot be achieved.
[0005] Referring to patent CN101851482B "Stone Jointing Adhesive", patent CN101805581B "Stone Jointing Adhesive", patent CN101851483B "A Stone Jointing Adhesive", the stone jointing adhesive used for seamless bonding has the following disadvantages: ①. Stone jointing adhesive It is mainly used to fill or fill the gap between stone and stone, so it has high requirements for shrinkage resistance and surface air-drying properties after colloid curing, but it does not have high requirements for bonding strength after colloid curing, which cannot reach zero. Strength requirements for seam bonding
②. When using stone pointing glue to seamlessly bond stone materials, if the coating is less, the bonding marks will be shallower, but it will easily lead to shedding; if the coating is more, the bonding marks will be more obvious, and it cannot be removed Fundamentally achieve the purpose of seamless bonding between stone and stone

preparation example Construction

[0038] A preparation method based on the above-mentioned stone seamless adhesive, comprising the following steps:

[0039] 1) Take the components according to the weight parts of the above-mentioned raw materials, and set aside;

[0040] 2) Stir the above components evenly at high speed under negative pressure with a vacuum degree of 0.08-0.1Mpa and a rotational speed of not less than 1500r / min. The stirring time is 30-45 minutes to obtain a stone seamless adhesive.

[0041] Adding cellulose substances in the present invention can obviously increase colloidal strength, and its reinforcing mechanism is as follows: cellulose has very high mechanical modulus and strength usually, when using unsaturated polyester resin as matrix, when reinforcing with cellulose, The matrix can produce plasticity under the action of stress, and the load is transmitted to the fiber, and the fiber bears the load. The matrix bonds and fixes the fibers and protects the fibers in a stable state, thus f...

Description

technical field [0001] The invention relates to the technical field of stone bonding glue, in particular to stone seamless bonding glue and a preparation method thereof. Background technique [0002] In recent years, with the development of the architectural decoration industry, stone has been widely used in the wall and floor finishes of large public buildings such as airports, subway stations, shopping centers, convention and exhibition centers, libraries, and more and more in star-rated hotels. And parquet decoration of high-end clubs, etc. Seamless bonding, decorative panels have gradually developed into the mainstream of decoration. In addition, the requirements for seamless splicing of handicrafts and ultra-thin ceramic products are also getting higher and higher.
