Problems solved by technology

The disadvantages of this method are: poor anti-blooming effect, increased process steps and increased cost
(2) Surface protection, which includes two types: a. Adding paraffin: the most common is to add paraffin to the formula, but paraffin can only be used as a protective agent under static conditions, and it is extremely unfavorable to latex products under dynamic conditions; It is also greatly affected by the ambient temperature, and after the paraffin is precipitated on the surface of the vulcanized rubber, the surface of the product will lose its luster, which is unfavorable to some latex products that require a beautiful appearance.
It is precisely because of the limitations of these conditions that this method has not been actually implemented and applied in actual production.
(3) Change the vulcanization method: a. Irradiation vulcanization: However, due to the constraints of many factors, it is difficult to use large-scale use of irradiated rubber in production
Its disadvantages are: due to the variability of the current process conditions, raw material performance and storage environment, this method cannot adapt to and meet such variable conditions, resulting in poor anti-frost effect
(5) Adsorption: Adding adjuvants with strong absorptive properties to absorb excess compounding agents has the disadvantages of difficult selection of adjuvants, high cost, difficulty in adapting to and satisfying changing conditions, and cannot fundamentally solve the problem of blooming
[0005] However, the above-mentioned prior art either uses graphene to coat the vulcanizing agent, or grafts the vulcanization accelerator to the surface of graphene, so graphene is ultimately an essential part of the rubber compound formulation, and it must have the following problems: First, the process is complicated, and it is necessary to coat sulfur particles or graft accelerators to the surface of graphene at specific temperatures, solvent environments, and acid-base environments; The amount is directly proportional, otherwise it will not be possible to coat the sulfur or graft all the accelerators, and too much graphene will cause the final rubber product to harden, and a large amount of graphene will also bring high costs; third, resulting in rubber products The phenomenon of blooming does not only contain sulfur or accelerators, but various other small molecule complexes are also components of blooming
Therefore, the above-mentioned technology can not effectively play the problem of suppressing the blooming of rubber products

Embodiment 1

[0048] Natural rubber gloves cured from the natural rubber gloves, intercepted 4 fingers on this glove, and 4 fingertips surfaces were rinsed with 95% ethanol scrubbing and purge. The A171 (vinyltrimethoxysilane) solution having a concentration of 1 wt% (the solvent is alcohol: water volume = 5: 5), the formulation concentration is 0.01% by weight, 0.05 wt%, 0.1% by weight of three different specifications of oxidation The graphene suspension is 150 ml. The oxide oxide in the three specification of the oxide inkylene suspension is produced from the same batch of Hummer's Method.

[0049] Four fingers were impregnated with tweezers to 4-5 s in the A171 solution, and were dried in an oven at 60 ° C. After drying, then three finger sleeve clamping and turned to the concentration of 0.01% by weight, 0.05 wt%, 0.1 wt% three specification, and completely impregnated 4- After 5S, it was taken out, and the observation was taken in an oven at 100 ° C.

[0050] Such as figure 1 As shown, th...

Embodiment 2

[0054] A natural rubber glove of a rubber glove was taken from the natural rubber gloves, and one finger sleeve was intercepted on the glove, and the surface of 1 finger sleeve was washed with 95% ethanol and washed.

[0055] The A151 (vinyl triethoxysilane) solution having a concentration of 1.5 wt% was formulated (the solvent was alcohol: water volume = 5: 5), and the concentration of 0.1% by weight of the oxide in graphene suspension was formulated 150 ml. Among them, oxidized graphene is from the Hummer's method.

[0056] The intercepted finger sleeve was immersed in a 151 solution to the A151 solution, and then dried in an oven at 60 ° C. After drying, remove the finger sleeve and turn the fingertips to the oxide oxide in the concentration of 0.1% by weight, and then removed from the oxide of 120 ° C and dried in an oven at 120 ° C. ,take out. After stirring in 200 ml of deionized water, it was repeated 3 times, and then dried at 100 ° C.

Embodiment 3

[0059] A natural rubber glove of the natural rubber gloves is taken from the natural rubber gloves (adding black color paste, making color for pure black gloves), intercepted three fingers on this glove, 3 finger sets 95% ethanol washed and rinsed after the surface was flushed.

[0060] The A171 (vinyltrimethoxysilane) solution having a concentration of 2 wt% (the solvent is alcohol: water volume = 5: 5), the formulated concentration of 0.01% by weight, 0.1% by weight of two specifications of the oxide inkylene suspension 200ml. The oxide oxide in the oxide insertioned oxide in the oxide inkylene is prepared from the same batch of Hummer's method.

[0061] Three fingers were extracted from 4-5 s of the A171 solution to the A171 solution, and then dried in an oven at 60 ° C. After drying, then two fingers were removed by nickerel, and then impregnated into the concentration of 0.01 wt%, 0.1% by weight, and then removed 4-5 s, place it together. Drying in an oven at 110 ° C and take...

Abstract

The invention relates to a surface treatment method for preventing rubber products from blooming. The method is as follows: after the rubber products are produced, a protective layer composed of two-dimensional materials is formed on the surface of the rubber film of the rubber products. Through the treatment of the method of the present invention, a layer of dense and stable protective layer is obtained on the surface of the rubber product, which prevents the migration of the compounding agent in the rubber product and blocks the entry of external destructive factors, so that the rubber film of the rubber product forms a closed system by itself, thereby achieving The purpose of preventing rubber products from blooming is to make rubber products have better weather resistance and durability while taking into account the appearance quality of rubber products.

Description

Technical field [0001] The present invention relates to the field of production techniques of rubber articles, and more particularly to a surface treatment method for preventing rubber products. Background technique [0002] The spray phenomenon refers to a migration of some small molecule compounds (various complexes) in rubber compound formula, precipitated in rubber products or semi-finished product, forming a layer of exudate similar to white cream attached to rubber semi-finished or vulcanized article surface The phenomenon. This phenomenon not only seriously affects the appearance and performance of the product, but also causes the user's skin to delay, such as a disposable natural latex gliped product, Ethylene rubber sealing strip, etc., due to the franches and user skin can be directly Contact, it will cause itchy skin, refurbisha. Therefore, it is significant of the combination of natural latex products to improve the quality of rubber products. [0003] There are also ...
