AI Technical Summary

Problems solved by technology

If the viscosity of the glue is too high, the amount of glue attached to the dipped cord fabric will be too large, which will make the dipped cord fabric hard and deteriorate the fatigue resistance. If the viscosity of the liquid is too low, the amount of glue attached to the dipped cord fabric will be insufficient, the overall physical properties of the cord fabric will not meet the standard, and it will become a defective product

Abstract

The invention discloses a chinlon 6 cord fabric dipping solution which is prepared from the following components in parts by weight: 13.6 to 16.3 parts of softened water, 37.3 to 40.5 parts of butadiene-vinylpyridine latex, 43.4 to 47.1 parts of RF (radio frequency) m-alpha liquid and 0.4 to 0.6 part of ammonia water, the total amount of the components is 100 parts, and the RF m-alpha liquid is prepared from the following components in parts by weight: 38.9 to 44.7 parts of softened water, 0.04 to 0.05 part of sodium hydroxide and 1.58 to 1.95 parts of resorcinol. And 2.3 to 2.7 parts of formaldehyde. The dipping solution has the advantages that an existing dipping solution formula and a preparation process are improved and optimized, the butadiene-vinylpyridine rubber latex component is added, styrene-butadiene latex and natural latex in the prior art are removed, and the proportion and the preparation method are optimized, so that the adhesive force and the stability of the dipping solution are improved, the phenomena of rubber spots and the like during dipping are avoided, and the dipping solution has a good application prospect. Meanwhile, the preparation cost of the impregnation liquid is reduced, and the method is suitable for industrial application.

Description

technical field [0001] The application relates to the field of production technology of nylon 6 dipped cord fabric, in particular to a dipping solution for nylon 6 cord fabric and a preparation method thereof. Background technique [0002] Cord fabric is a skeleton fabric for rubber products such as tires woven with strong strands as warp and medium and fine count single yarns as weft. The warp threads are arranged closely, and the weft yarns are arranged sparsely, which looks like a curtain, so it is called cord fabric. They are subjected to enormous pressure, shock loads and strong vibrations. Cord fabric is an important material that affects tire performance and life. [0003] Nylon 6 cord fabric needs to be immersed in the dipping solution for dipping during production. The adhesion of the dipping solution is closely related to the performance of the cord fabric. The strength tends to increase. This is because the bonding between the fiber and the latex is mainly by h...
