Example Embodiment

[0016] The present invention will be further described in detail below in conjunction with specific embodiments. The embodiments may enable the professional and technical personnel in the field to understand the present invention more comprehensively, but do not limit the present invention in any way.

[0017] The preparation method of the organic-inorganic composite adhesive in the present invention includes the following steps:

[0018] (1) Under stirring at 300r / min, add 10-20 parts by mass of orthosilicate and 20-30 parts by mass of long-chain silane coupling agent to the mixture of 20 parts by mass ethanol and 20 parts by mass isopropanol. In the mixed solution, after mixing uniformly, use concentrated hydrochloric acid to adjust the pH value of the solution between 1 and 2;

[0019] (2) Add 5-10 parts by mass of deionized water to the mixed solution obtained in step (1) under stirring at 200-300r / min, and react at 40-60°C for 6-8 hours;

[0020] (3) Add 10-15 parts by mass of t...

Abstract

The invention relates to the field of building decoration materials, and aims to provide a preparation method of an organic-inorganic composite adhesive. The method comprises the following steps: adding tetraethyl orthosilicate and a silane coupling agent with a long chain into a mixed solution of ethanol and isopropyl alcohol under stirring, performing uniform mixing, and adjusting the pH of thesolution to 1-2 by using concentrated hydrochloric acid; adding deionized water into the mixed solution under stirring, and performing a reaction for 6-8 h at 40-60 DEG C; and adding hexafunctional UVresin into the obtained product, performing uniform mixing to obtain the organic-inorganic composite adhesive. According to the preparation method provided by the invention, the organic-inorganic composite adhesive prepared by the method has a low curing temperature and a simple and convenient processing technology, and inorganic particles have high adhesion strength on a substrate, and accidentscaused by fall are not easy to have.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a preparation method of an organic-inorganic composite adhesive. Background technique [0002] With the development of the economy, people's demand for decorative building materials with novel and beautiful appearance is increasing. Inorganic waste particle materials such as glass particles and ceramic particles are decorated on the glass to have a novel appearance, and at the same time, the raw material cost is low. But bonding these particles to the base material (stone, metal, cement, etc.) requires a suitable adhesive, otherwise it is easy to fall off. The invention prepares an organic-inorganic composite adhesive for bonding glass particles, and coats it on the surface of building flat glass to obtain a glass plate with a decorative function. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defi...
