Unsaturated polyester resin accelerant as well as preparation method and application thereof

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: 69 to 89.5 percent of methanol, 0.5 to 1 percent of copper acetate, 5 to 10 percent of cobalt iso-octoate and 5 to 20 percent of water. The invention also provides a preparation method of the unsaturated polyester resin accelerator, which comprises the following steps: mixing methanol, copper acetate, cobalt iso-octoate and water, and stirring for 30-60 minutes to obtain the unsaturated polyester resin accelerator. The accelerator product system is stable, the layering phenomenon cannot occur after long-time standing, and the problem of layering of an existing accelerator system is solved. A resin product prepared from the accelerator is good in curing effect and high in hardness, and the phenomenon that the resin is sticky to hands and becomes soft is avoided. The unsaturated polyester resin accelerator can shorten the gelling time and improve the production efficiency, the highest exothermic peak temperature in the resin curing process is similar to that of commercially available products, the curing effect is ideal, and the unsaturated polyester resin accelerator can replace existing products.

Description

technical field [0001] The invention relates to the technical field of accelerators, in particular to an unsaturated polyester resin accelerator and its preparation method and application. Background technique [0002] Artificial stone is made of high molecular polymer, inorganic gelling agent or a mixture of the two as the binding material, natural stone crushed (powder) material, aluminum hydroxide powder, etc. , Condensation and solidification and other processes processed stone. According to the gel material used and the function of use, 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 is the resin-type artificial stone produced with unsaturated polyester resin as the adhesive. [0003] Peroxide is added to the unsaturated polyester resin as an initiator / curing agent to cause the curing reaction of the resin. During this process, it is often necessa...

AI Technical Summary

Problems solved by technology

Because the traditional copper naphthenate contains water-insoluble solvents, in the formula system with water, the water-insoluble solvents will precipitate, causing the product to separate, resulting in unstable gel time, affecting the stability of production efficiency, and It will also lead to incomplete curing reaction, making the final product sticky and soft, lacking hardness
