Unsaturated polyester resin for grating and preparation method of unsaturated polyester resin

Abstract

The invention discloses unsaturated polyester resin for a grating and a preparation method of the unsaturated polyester resin, and belongs to the technical field of unsaturated polyester and preparation thereof. The unsaturated polyester resin is used as a matrix and can be prepared into a plate material with a plurality of spaces through a special processing technology, and the unsaturated polyester resin is the unsaturated polyester resin for the grating. The common unsaturated polyester resin product for the grating in the existing market is restricted by a processing technology, the cost is high, and the product often has a bubble phenomenon and is easy to crack, so that the application field of the grating type unsaturated polyester resin is limited. According to the unsaturated polyester resin for the grating and the preparation method of the unsaturated polyester resin, polyhydric alcohol terephthalate, ethylene glycol, diethylene glycol, benzoic acid, maleic anhydride and styrene are utilized, the unsaturated polyester resin for the grating is excellent in mechanical property and high in corrosion resistance, and the application field of the unsaturated polyester resin grating is effectively widened.

Description

technical field [0001] An unsaturated polyester resin for grids and a preparation method thereof belong to the technical field of unsaturated polyester and its preparation. Background technique [0002] With some kind of glass fiber as reinforcing material and unsaturated polyester resin as matrix, a plate material with many spaces can be prepared through special processing technology. The above unsaturated polyester is the unsaturated polyester resin for grid. [0003] Unsaturated polyester resin products for grilles are used in all walks of life in society and play an irreplaceable role in human society. They can be used in petroleum, electronic chemical industry, electroplating, green belt tree grate, decoration, square fountain, civil building facilities , transportation industry, wet and slippery processing plants, operating platforms, aquaculture fence double-layer floor and other areas. [0004] However, the existing unsaturated polyester resin products commonly used...

AI Technical Summary

Problems solved by technology

[0004] However, the existing unsaturated polyester resin products commonly used in the market are restricted by the processing technology, the cost is high, and the products often have bubbles, cracks and easy to crack, and because the commonly used unsaturated polyester resin for the grid itself The overall performance is generally low, which limits the use of grid-type unsaturated polyester resins

[0005] There are often highly corrosive liquids and gases in pharmaceutical factories, smelters, chemical treatment workshops, offshore platforms and other environments. It is difficult for ordinary plastic or resin grids to be used as shelves and floor materials to maintain working performance in the above-mentioned environments for a long time. Therefore, in the above-mentioned environments Only hard, expensive cement, metal, etc. can be used as floor coverings or shelves
