Embodiment 1

[0019] Example 1, based on the production of 1000kg of the water-soluble resin, 300kg of oxalic acid, 150kg of maleic anhydride, and 300kg of diethylene glycol were added to the reactor, and nitrogen protection was introduced, and slowly heated to 80-100°C, the highest 95°C, after all the reactants are melted, start electric stirring, raise the temperature to 190-210°C, keep warm until the acid value drops below 200°C, start to cool down to 100-130°C, add diethanolamine dropwise, dropwise time For 45 minutes, after the dropwise addition was completed, it was incubated for another 1.5 hours. After the heat preservation is over, lower the temperature to below 95°C, add glacial acetic acid, and keep heat for 30 minutes to obtain the resin.

Abstract

The invention relates to water-soluble resin, which is synthesized from the composition comprising the following components by the weight percentage: 5% to 15% of maleic anhydride, 15% to 30% of diethylene glycol, 25% to 35% of oxalic acid, 15% to 25% of diethanol amine and 5% to 20% of acetic acid, wherein the component of diethanol amine is preferably 20% to 23%. The resin is prepared through the following steps: pumping nitrogen into a reaction kettle for protection; heating slowly; stirring, heating up and heat-insulating; and cooling and further heat-insulating. The water-soluble resin can be adopted as the composition of the domestic enhanced glass fiber sizing agent so as to improve the textile performance of the glass fiber, improve the monofilament tension and enhance the toughness, thereby meeting the requirements for the subsequent production.

Description

technical field [0001] The invention relates to a water-soluble resin in a glass fiber sizing agent. Background technique [0002] The most common methods of glass fiber production are: pool kiln wire drawing and crucible wire drawing. When the molten liquid glass flows out of the orifice plate by its own weight, it is drawn into a glass fiber monofilament with a very fine diameter by a wire drawing machine during the rapid cooling process. It must be through the action of sizing to produce soft and good toughness for the weaving of glass fiber. [0003] At present, SR-1 resin is the most widely used domestic reinforced glass fiber sizing agent. Although this resin has the advantages of good thermal stability and convenient use, it is found in the production practice that the glass fiber processed by this resin has poor textile performance. The high production cost makes some manufacturers have to change production. Based on this, it is very necessary to develop a resin wit...
