Abstract

The invention discloses a high-property sealing adhesive for an indoor decoration board and a preparation method thereof, and relates to the technical field of decoration materials. The high-propertysealing adhesive is prepared from the following raw materials of modified epoxy resin, hydroxypropyl methyl cellulose, Faku clay, modified sanidine powder, a re-dispersible latex solution, silicone master batch, triethanolamine, lignosite, trisphosphine oxide, a coupling agent, a plasticizer and an accelerant TMTD. The preparation method comprises the following step of mixing the raw materials toreact, so as to obtain the high-property sealing adhesive. The high-property sealing adhesive has the advantages that the high-property sealing adhesive is simple and convenient; the adhering property, anti-seepage and anti-freezing properties, flame-retardant and high temperature-resistant properties, anti-corrosion and anti-aging properties and the like are excellent, and the comprehensive property is excellent; the application occasions are wide, and the service life of a product is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a high-performance interior decorative panel sealing adhesive and a preparation method thereof. Background technique [0002] With the rapid development of material science and construction industry, the update speed of new building materials and decorative materials is getting faster and faster, moving towards the direction of integration of high performance, all aspects, energy saving and environmental protection. However, due to the high brittleness of traditional adhesives for architectural decoration, the adhesive force between the adhesive and the substrate will be reduced due to mechanical stress and temperature changes during use, and it will also lead to cracking and electrical performance degradation, which will affect the electronics. The reliability of the long-term operation of the product. Contents of the invention [0003] Aiming at the problems exi...
