Problems solved by technology

For example, with cement and modified cement adhesive, the construction period is long, the bonding strength is low, and it is not beautiful; the use of hot-melt acrylic adhesive or polystyrene adhesive, which contains more than 40% of low-molecular solvents, has a large volatile content and pollutes the air. , which is not good for the health of decoration construction workers; epoxy resin is mainly used to make glue on site in China, which is inconvenient for construction; there are also two-component adhesives prepared with epoxy, which are mainly suitable for suspension and anchoring of stone materials, and are used for mosaic laying and decoration. There is a phenomenon that the curing agent seeps out and pollutes the surface of the light-colored stone

Abstract

The present invention relates to a stone material adhesive and its preparation. The adhesive is especially sutiable for laying floor of marble, granite, ceramic tile, etc. It consists of dicyclopentadiene type unsaturated resin, densifier, stuffing, pigment, defoaming agent, curing agent, promoter, polymerization inhibitor and coupling agent. It includes two components capable of being cured at normal temperature fast and at low temperature and has no smell, no pollutant, high strength, good cure effect and storage period as long as one year.

Description

technical field [0001] The invention relates to an adhesive and its preparation, in particular to an adhesive for laying, mosaicing and jointing of marble, granite, tiles and other stone materials and its preparation. Background technique [0002] With the vigorous development of the construction industry and the decoration industry, the use of stone and the amount of decoration are increasing, and the original bonding process and adhesives have many shortcomings. For example, with cement and modified cement adhesive, the construction period is long, the bonding strength is low, and it is not beautiful; the use of hot-melt acrylic adhesive or polystyrene adhesive, which contains more than 40% of low-molecular solvents, has a large volatile content and pollutes the air. , which is not good for the health of decoration construction workers; epoxy resin is mainly used to make glue on site in China, which is inconvenient for construction; there are also two-component adhesives p...
