Description

TECHNICAL FIELD

[0001] The present application relates to the field of water glue slurry cord, and particularly relates to a water glue slurry of water glue slurry cord and a use method thereof. BACKGROUND

[0002] Gasoline slurry is a very important formula in the production process of V-belt. The traditional method is to mix the rubber uniformly in the internal mixer, and then dissolve the rubber with gasoline. When used in the workshop, the dissolved slurry is first poured into the slurry tank, and the cord passes through the slurry tank to attach the slurry on the surface, thereby achieving the operating viscosity of the thin skin rubber.

[0003] Currently, gasoline slurry is used in the production of wrapped V-belt, and some problems occur during the use of the slurry. (1) The slurry is dissolved by gasoline, and there is a certain safety hazard in the transportation, storage and use of gasoline. The slurry preparation workshop has had several fire safety hazards in the past. (2) Due to the use of slurry, there is a strong gasoline smell in the next workshop, and the lead, ether, alkane and other chemical substances in gasoline are easily inhaled by workers for a long time, which can easily cause occupational diseases. (3) Flying dust is easily generated when the cord passes through the slurry, which causes the workshop environment to deteriorate and seriously affects the 5S of the workshop. (4) When the gasoline slurry is prepared manually, the gasoline is easily volatilized, which makes it difficult to control the concentration of the slurry, and causes the yarn tension to be unstable when the cord passes through the yarn, thereby affecting the stability of the length of the cord. (5) The gasoline used at the same time is also a kind of energy consumption, which occupies the energy consumption and carbon emission indicators.

[0004] Therefore, it is important to provide a water glue slurry cord without the gasoline slurry step. SUMMARY

[0005] The present application aims to provide a water glue slurry of water glue slurry cord and a use method thereof, and the specific scheme is as follows:

[0006] A water glue slurry of water glue slurry cord, comprising a one-bath activation immersion liquid, a two-bath RFL immersion liquid and a three-bath water glue slurry immersion liquid;

[0007] The one-bath activation immersion liquid comprises the following mass fraction formula: 1-10 parts of waterborne isocyanate, 1-10 parts of epoxy resin and 80-100 parts of deionized water;

[0008] The two-bath RFL immersion liquid comprises the following mass fraction formula: 1-10 parts of ammonia, 1-10 parts of resorcinol-formaldehyde condensate, 1-5 parts of formaldehyde, 30-50 parts of butyl pyrrole latex, 1-10 parts of natural latex, 5-10 parts of liquid carbon black and 50-100 parts of deionized water;

[0009] The water glue three bath impregnating solution includes the following mass fraction formula: 1-5 parts of water-based zinc oxide, 1-5 parts of water-based sulfur, water-based accelerator DM, 1-5 parts of water-based tackifying resin, 20-50 parts of natural latex, 20-50 parts of butyl pyrrole latex, 1-10 parts of liquid carbon black, and 40-80 parts of deionized water.

[0010] The preparation method of the one-bath activation impregnating solution is as follows: deionized water is added to a reaction kettle, and epoxy resin and water-based isocyanate are sequentially added under moderate stirring until the raw materials are completely dissolved.

[0011] The preparation method of the two-bath RFL impregnating solution is as follows: water is added to a reaction kettle, and ammonia water, resorcinol and formaldehyde condensate are sequentially added and stirred until the raw materials are completely dissolved to prepare solution A; water is added to the reaction kettle, formaldehyde is added, and stirring is performed for 1-5 minutes to prepare solution B; ammonia water, butyl pyrrole latex and natural latex are sequentially added to the reaction kettle to prepare solution C; solution A is first added to solution C, then solution B is added to solution C, and then liquid carbon black is added to solution C; after stirring for 10-30 minutes, the RFL impregnating solution is finally prepared.

[0012] The RFL impregnating solution is aged at 20-30℃ for 8-24H before use.

[0013] The preparation method of the water glue three bath impregnating solution is as follows: water is added to a reaction kettle, and water-based zinc oxide, water-based sulfur, water-based accelerator DM and water-based tackifying resin are sequentially added and stirred at low speed for 10-30 minutes to prepare solution A; water is added to the reaction kettle, and natural latex and butyl pyrrole latex are sequentially added and stirred at low speed for 1-5 minutes to prepare solution B; solution A is added to solution B, and then liquid carbon black latex is added to solution B to finally prepare the water glue three bath impregnating solution.

[0014] A method for using water glue of a water glue cord, after twisting the polyester fiber, immersing it in a one-bath activation impregnating solution, then heating treatment in an oven, wherein the oven temperature is 200-230℃, immersing it in a two-bath RFL impregnating solution, then heating treatment in an oven, wherein the oven temperature is 220-260℃, immersing it in a water glue three bath impregnating solution, then heating treatment in an oven, wherein the oven temperature is 100-150℃, and drying.

[0015] The cord used in the V-belt industry currently needs to go through gasoline slurry impregnation process in the process of preparing V-belt. The cord after gasoline slurry impregnation process has certain operating tackiness, which can be combined with rubber in the process of forming and yarn pulling, and then the next process operation can be carried out. The water slurry cord can go through the formula of water slurry three bath, that is, it can meet the adhesion with rubber and the operating tackiness with rubber, so that the gasoline slurry process step can be removed.

[0016] The water slurry cord can remove the gasoline slurry process, achieve the operating tackiness and adhesion effect with rubber, remove the gasoline slurry process, and can have the effects of environmental protection, energy consumption and carbon reduction, and by adjusting the formula, the adhesion can be improved.

[0017] The adhesion of the water slurry cord and rubber is mainly through the reaction between the one-bath activation impregnation liquid and the two-bath RFL impregnation liquid and the rubber to form the adhesion effect. The water-based zinc oxide, sulfur and accelerator in the water slurry three bath can play a corresponding role when the water slurry cord is adhered to the rubber. The latex added in the water slurry three bath can provide certain adhesion. The ratio of butyl rubber latex and natural latex is adjusted to achieve the optimal value of operating tackiness and adhesion. The water-based tackifying resin can provide certain operating adhesion to the surface of the cord, so as to meet the operating tackiness requirement in the next use process. DETAILED DESCRIPTION

[0023] Water slurry preparation

[0024] The preparation method of the one-bath activation impregnating solution is as follows: deionized water is added to the reaction kettle, and then epoxy resin and aqueous isocyanate are added in sequence under moderate stirring until the raw materials are completely dissolved.

[0025] The preparation method of the two-bath RFL impregnating solution is as follows: water is added to the reaction kettle, and then ammonia water, resorcinol and formaldehyde condensate are added in sequence under stirring until the raw materials are completely dissolved to prepare solution A; water is added to the reaction kettle, and then formaldehyde is added under stirring for 1-5 minutes to prepare solution B; water is added to the reaction kettle, and then ammonia water, butyl pyrrole latex and natural latex are added in sequence to prepare solution C; solution A is first added to solution C, then solution B is added to solution C, and then liquid carbon black is added to solution C; after stirring for 10-30 minutes, the RFL impregnating solution is finally prepared; the RFL impregnating solution is aged at 20-30°C for 8-24 hours before use.

[0027] Use method of water-based paste of water-based paste cord

[0028] After the polyester fiber is twisted, it is immersed in the one-bath activation impregnating solution, and then is subjected to heat treatment in an oven with a temperature of 200-230°C; then it is immersed in the two-bath RFL impregnating solution, and then is subjected to heat treatment in an oven with a temperature of 220-260°C; then it is immersed in the three-bath water-based paste impregnating solution, and then is subjected to heat treatment in an oven with a temperature of 100-150°C for drying.

[0029] Experimental discussion

[0030] In the specific implementation process, through different formula test cases, for example, in the three-bath water-based paste, the proportion of natural latex: butyl pyrrole latex decreases as the proportion of natural latex decreases and the proportion of butyl pyrrole latex increases, and the water-based paste cord shows increased adhesion to the cord but decreased adhesion to the rubber in the downstream process; on the contrary, when the proportion of natural latex increases and the proportion of butyl pyrrole latex decreases, the water-based paste cord shows excellent adhesion in the downstream process but decreased adhesion to the cord; two extremes, i.e., all latex is natural latex, show the best operating adhesion, and all latex is butyl pyrrole latex, shows the best adhesion to the rubber (the proportion of the claim obtained by experiment is the best).

[0031] The content of the water-based tackifying resin is tested for several rounds, from 1% to 3%, and the test results show that 1% content can meet the process requirements. With the increase of the content, the three immersion amount of the water-based paste attached to the surface of the wire rope increases, which has an impact on the overall processing, so 1% content can meet the corresponding requirements.

[0032] The water-based zinc oxide, vulcanization, and accelerator DM are necessary additives. Without these raw materials, the adhesion between the water-based paste wire rope and the rubber is poor, but these additives cannot be too much. Through multiple rounds of tests, the specific addition amount (i.e., the range described in the claims) can be obtained.

[0033] The test results of the product of the present application show that the adhesion performance is close to that of the conventional formula (although the present application is environmentally friendly and has low energy consumption), and the adhesion in the subsequent processing process is better than that of the conventional formula.

[0034] The above describes the technical principles, advantages, and characteristics of the present application. It should be noted that the above is only a preferred embodiment of the present application, but is not limited by the above examples. For those skilled in the art to which the present application belongs, some improvements and optimizations can be made without departing from the content of the present application, which should be considered as belonging to the protection scope of the present application.
