Problems solved by technology

[0002] The countertops in high-end laboratory furniture are still used in the market today, including cement tiles, laminated physical and chemical panels, natural marble, and ceramic panels. One of the common points of the above-mentioned panels is that they are easy to crack after a period of use. The service life is short. After the countertop is cracked, the usual method is to replace the countertop. Replacing the countertop is time-consuming, laborious and expensive, resulting in a great waste of resources.

Abstract

The invention relates to a preparation method of an epoxy resin profile. The preparation method comprises the following steps that raw materials are uniformly mixed to obtain a mixture, and the mixture is preheated; the mixture is distributed, so that the mixture is uniformly distributed on a transmission device; the mixture on the transmission device is subjected to gradient heating, and then themixture is segmented to obtain a semi-finished product; the semi-finished product is subjected to heat preservation; the semi-finished product after heat preservation is pressed into a mold to be molded to obtain the epoxy resin profile, and the semi-finished product is subjected to gradient cooling in the forming process; and after the epoxy resin profile and the mold are cooled, demolding and blanking and forming are carried out, and then a film pasting is carried out to obtain an epoxy resin profile finished product. The epoxy resin mixture is subjected to gradient heating during gelationand curing to form an epoxy resin cured product, and the epoxy resin cured product adopts gradient cooling in the forming process of the epoxy resin cured product, so that internal stress generated inthe preparation process of the epoxy resin profile is reduced, cracks generated in the preparation process are reduced, and the problem that the finished product is prone to cracking after a period of time is used is reduced.

Description

technical field [0001] The invention relates to the field of epoxy resin, in particular to a method for preparing an epoxy resin profile. Background technique [0002] The countertops in high-end laboratory furniture are still used in the market today, including cement tiles, laminated physical and chemical panels, natural marble, and ceramic panels. One of the common points of the above-mentioned panels is that they are easy to crack after a period of use. The service life is short, and the usual method after the countertop is cracked is to replace the countertop, which is time-consuming, laborious and expensive, resulting in a great waste of resources. Contents of the invention [0003] The purpose of the present invention is to provide a durable, non-porous surface and a preparation method for an epoxy resin profile that is not easily cracked. [0004] Concrete technical scheme of the present invention is as follows: [0005] A preparation method of epoxy resin profil...
