The invention discloses a water-dispersible sizing agent for chopped glass fibers, which comprises two nitrogen-containing organic compound mixture dispersants, composed of one or more polyhydric or carbonyl alcohols, esters, acyl polymers The protective agent composed of polyol mixture is composed of moisturizing agent, lubricant, silane coupling agent commonly used in the glass fiber industry, and the rest is deionized water or distilled water. The sizing agent is suitable for the dispersion of various alkali-free and medium-alkali glass fibers in aqueous media. The glass fiber treated by this product has good dispersion performance, good thermal stability and no pollution.
Description
Technical field [0001] The invention relates to a water-dispersible glass fiber surface treatment agent. Background technique [0002] Disperse glass fiber in water or water alcohol and ester solution medium, and then be used to produce glass fiber insulation packaging material, glass fiber mat, especially glass fiber mixed with polymer resin fiber to make glass fiber reinforced resin and other high-strength glass Fiber composite material is an important field of modern glass fiber application, and has a broad market and development prospects. [0003] Currently commonly used water-dispersible glass fiber sizing agents mostly use amine or alcohol single compounds or a mixture of non-ionic and cationic surfactants as dispersants, such as US patents, patent numbers US.717278, US.422771, US .834990. Its shortcomings are that it is difficult to adjust according to the actual situation of industrial production, and it cannot meet the actual needs of dispersing various types and chemic...
