Problems solved by technology

Because of its high viscosity, dark color, many impurities, unstable quality, and difficult to operate in winter construction, it is difficult to meet user requirements
Moreover, the unsaturated resin will release a lot of heat during the curing process. When unsaturated resin is used as the bonding material to prepare thick artificial stone products, due to the thickness of the product, the heat released by the unsaturated resin during the curing process cannot be removed in time. Often lead to cracking and scrapping of finished products

Abstract

The invention belongs to the technical field of accelerators, and particularly relates to an unsaturated polyester resin accelerator as well as a preparation method and application thereof. The unsaturated polyester resin accelerant is prepared from the following raw materials in percentage by mass: 79 to 94.5 percent of methanol, 5 to 20 percent of copper naphthenate or copper isooctanoate and 0.5 to 1 percent of cobalt isooctanoate. The invention also provides a preparation method of the unsaturated polyester resin accelerator, which comprises the following steps: mixing methanol, copper naphthenate or copper isooctanoate and cobalt isooctanoate, and stirring for 30-60 minutes to obtain the unsaturated polyester resin accelerator. The unsaturated polyester resin accelerator can shorten the gelling time of resin, can reduce the exothermic peak temperature of a resin product, can effectively prevent the problems of cracking, deformation and the like of a thick product, and is suitable for preparation of an artificial stone thick product.

Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to an unsaturated polyester resin accelerator and a preparation method thereof, and an adhesive for preparing artificial stone obtained by using the unsaturated polyester resin accelerator. Background technique [0002] Artificial stone is made of high molecular polymer, inorganic gelling agent or a mixture of the two as the bonding material, natural stone crushed (powder) material, aluminum hydroxide powder, etc. as the main raw materials, adding pigments and other auxiliary agents, stirring and mixing , coagulation and solidification and other processes processed stone. According to the different gel materials and functions used, artificial stone can be divided into resin type artificial stone, inorganic type artificial stone, functional artificial stone and so on. At present, the most widely used resin-based artificial stone is produced with unsaturated polyester resin as a...
