Problems solved by technology

[0002] The countertops in high-end laboratory furniture are still used in the market today, such as cement tiles, melamine boards with anti-corrosion rubber, laminated physical and chemical boards, natural marble, and ceramic boards. One of the common points of the above boards is That is, there is only a very thin layer of anti-corrosion on the surface of the material, and the base material cannot be anti-corrosion. If the surface is damaged, the entire countertop will be deformed, bent, and cracked until the countertop is replaced. This may cause damage to personnel and equipment, and the countertop needs to be replaced. Time-consuming, laborious and costly, resulting in a great waste of resources

Abstract

The invention discloses an epoxy resin material with strong corrosion resistance, and a method for preparing an integral core-penetrating plate by using the same. The epoxy resin material comprises the following components: an epoxy resin matrix, an epoxy resin curing agent, quartz sand, an epoxy resin diluent, a coupling agent and color paste. The method for preparing the core-penetrating plate comprises the following steps: pre-heating the epoxy resin matrix, the epoxy resin curing agent and the quartz sand, respectively; putting the pre-heated epoxy resin matrix in a pre-heated reaction kettle, adding the pre-heated quartz sand with half in weight, stirring the mixture, and then inputting the pre-heated epoxy resin curing agent and residual quartz sand; after stirring the mixture, inputting the epoxy resin diluent and the color paste; and after stirring the mixture, inputting a crosslinking agent, injecting the mixture into a pre-heated die after reaction, isolating heat and carrying out crystallization and deforming reactions sequentially, then reducing the temperature to 170-200 DEG C and preserving the temperature for 3-4 hours, and finally, cooling the mixture to room temperature to obtain a product. The product disclosed by the invention is durable. If damages are produced on the surface, the product can be directly repaired like a new one.
