Problems solved by technology

[0004] At present, there is no alkali-free direct yarn sizing specially developed for grinding wheel reinforcement sheets in the industry. The common alkali-free direct yarn used for grinding wheel reinforcement fabrics mainly has the following problems: 1. It is not resistant to textiles, and wool yarn is easily produced during the weaving process; 2. The strength cannot meet the customer's requirements; 3. The combination effect of the yarn and the resin for impregnating the reinforced cloth is not good

preparation example Construction

[0050] The preparation method of alkali-free direct yarn sizing agent of the present invention is:

[0051] (1) Set the required weight of deionized water to 100 parts, add 15 to 25 parts of deionized water at 20 to 30°C in the preparation kettle, add glacial acetic acid and stir for 5 to 10 minutes, add coupling agent in proportion, and stir for 30 to 40min;

[0052] (2) Dissolve and dilute the lubricant with 10-20 parts of deionized water at 60-80°C, and add it to the preparation kettle;

[0053] (3) Dilute the epoxy emulsion and water-soluble epoxy resin with 5-15 parts of deionized water respectively, and add them to the preparation kettle;

[0054] (4) Dilute the polyester emulsion with 5 to 15 parts of deionized water and add it to the preparation kettle;

[0055] (5) Dissolve the new additive A with 2 to 4 parts of deionized water and add it to the preparation kettle;

[0056] (6) Dissolve the new additive B with 2 to 4 parts of deionized water and add it to the prep...

Abstract

The invention discloses a special alkali-free direct yarn wetting agent for grinding wheel reinforcing sheets and a preparation method thereof. The alkali-free direct yarn wetting agent comprises the following components in percentage by mass: 2-6% of epoxy emulsion, 1-5% of polyester emulsion, 0.2-0.6% of water-soluble epoxy resin, 0.2-0.8% of lubricant, 0.05-0.3% of antistatic agent, 0.8-1.4% of coupling agent, 0.2-2% of novel assistant A, 0.1-1% of novel assistant B, 0.1-0.5% of glacial acetic acid and the balance of deionized water. Various components are adopted to endow the yarn with high power and favorable permeation effect in the dipping treatment process. Multiple high-performance lubricants are utilized, and the two novel assistants are introduced, thereby implementing favorable weaving effect on the premise of ensuring favorable permeation effect. The two coupling agents are combined to well ensure the combination effect between the glass fiber and resin.

Description

technical field [0001] The invention relates to an alkali-free textile direct yarn sizing agent, in particular to a special alkali-free glass fiber sizing agent for a grinding wheel reinforcement sheet which can be used for both warp and weft yarns of a grinding wheel reinforcement cloth, and also relates to a preparation method of the alkali-free direct yarn sizing agent. Background technique [0002] Glass fiber reinforced grinding wheel uses glass fiber mesh as the reinforcing base material of the grinding wheel to improve the overall strength of the grinding wheel. It has been used in China for many years. Grinding wheels with glass fiber mesh as reinforcement are widely used in mechanical metallurgy, construction, military industry, railway construction, fire-fighting and demolition and other fields. [0003] As the selective reinforcement of glass fiber reinforced grinding wheel, it is generally necessary to process glass fiber into unidirectional or multiaxial fabric....
