Polyester resin for high-weather-resistance double-component matte sand-streak transfer printing and preparation method thereof

Abstract

The invention relates to the field of preparation methods of two-component polyester resin, in particular to high-weather-resistance two-component polyester resin for matte sand-streak transfer printing and a preparation method thereof. The preparation method comprises following steps: step one, checking the equipment; step two, feeding step by step; step three, stirring and heating; step four, carrying out preliminary sampling and detection; step five, cooling and feeding; step six, performing heat preservation sampling and detection; step seven, carrying out vacuum sampling and detection; step eight, cooling; step nine, curing and catalyzing; step ten, filtering and crushing; and step eleven, packing the finished product. The preparation method disclosed by the invention has the beneficial effects that by arranging the two-component polyester resin, the high weather resistance of the polyester resin in a matte sand-streak transfer printing process is realized, so that a coating subjected to transfer printing is not pulverized, does not fade and does not fall off in a natural environment for a long term, by adding a curing catalyst, a layer of transparent protective film is formedon the surface of polyester resin, and the polyester resin has excellent insulation, moisture resistance, electric leakage resistance, shock resistance, dust resistance, corrosion resistance, aging resistance, corona resistance and the like.

Description

technical field [0001] The invention relates to the field of preparation methods of two-component polyester resins, in particular to a high-weather-resistant two-component matte chauvin transfer polyester resin and a preparation method thereof. Background technique [0002] Polyester resin is divided into saturated polyester resin and unsaturated polyester resin. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments and fillers, initiators and other additives. The adhesive has low viscosity, easy wetting, and good manufacturability. The cured adhesive layer has high hardness, good transparency, high brightness, can be quickly cured under pressure at room temperature, has good heat resistance, and excellent electrical properties.

AI Technical Summary

Problems solved by technology

[0003] During the use of the existing polyester resin in matt chauvin transfer printing, due to the large shrinkage rate of the polyester resin, low adhesive toughness, poor chemical medium resistance and water resistance, the polyester resin is easily affected by air. and water vapor corrosion, resulting in a decline in transfer quality

[0004] To this end, a high weather resistance two-component matt chauvin transfer polyester resin and its preparation method are provided to solve the corrosion resistance problem of polyester resin
