Novel chinlon cord thread oil agent and preparation method thereof

Abstract

The invention discloses a novel chinlon cord thread oil agent and a preparation method thereof. A cord thread oil agent composition consists of the following ingredients in percentage by weight: (a) 5 to 50 percent of synthetic ester, (b) 10 to 70 percent of modified end sealing polyether, (c) 5 to 40 percent of polyether, (d) 1 to 15 percent of anti-static agents, (e) 5 to 15 percent of emulsifying agents and (f) 1 to 3 percent of additives. When products prepared according to the invention are used, the anti-static effect is good, the spinnability after the use is good, the strength loss after the original silk twisting weaving is small, and in addition, the compatibility of the oil agent and latex is good. The oil agent has stable performance, is convenient to use and has good compatibility with water. In addition, in the false twisting process, the tension is automatically regulated to the reasonable surface tension, and the tar formation can be inhibited, so the stable operation can be prolonged in the false processing step. The smoothness and the heat resistance performance are excellent, the process requirements of chinlon cord thread spinning can be met, and in addition, the biodegradability is good.

Description

technical field [0001] The invention relates to a novel nylon cord oil agent and a manufacturing method thereof, belonging to the technical field of auxiliary agent manufacturing in synthetic fiber processing technology. Background technique [0002] Tire cord is the reinforcing material of tires. In the past, viscose fiber was mainly used as raw material. With the development of synthetic fibers, nylon, polyester, aramid, etc. are also used. Nylon cord is widely used due to its excellent heat resistance, impact resistance and fatigue resistance. Since the 1980s, my country has introduced several sets of high-speed spinning cord production equipment, and the corresponding oil agents are all dependent on imports. The price of these oil agents is relatively expensive, and it takes a lot of foreign exchange every year. In recent years, some domestic manufacturers have successively developed some nylon cord oil agents. However, due to problems in research and development techn...

Problems solved by technology

[0004] There are two types of existing oil compositions, one is ester type, most of which are based on natural esters, such as US4293460, which mainly consists of natural oils, polyoxyethylene alkylphenols, phosphates, etc., and its characteristics It has strong adhesion with rubber, low strength loss after twisting and weaving of raw silk, but poor spinnability and high degree of tarring; the other is polyether type oil composition, such as CN242451A, from 60 to 90% of ethylene oxide and propylene oxide copolyether, the rest of antistatic agent and defoamer, etc., among which polyether is unmodified ordinary polyether, which is characterized by good spinnability and smoke Less, low degree of tarring, the disadvantage is that the strength loss after twisting of the raw yarn is high, and the compatibility between the oil agent and the latex is poor, resulting in poor adhesion between the cord fabric and the tire

Although the patent CN1540088A adopts modified polyether, the various application properties in the use process are better, but the adhesive performance improver used in it is an alkylphenol compound or an aromatic compound, which has a strong ecotoxicological effect and Bioaccumulation has been gradually eliminated, and the phosphate salts used in it will also cause eutrophication of water bodies and have a greater impact on the environment
