Problems solved by technology

[0003] At present, most of the wrinkle gloves on the market are natural latex wrinkle gloves (natural rubber is a non-polar rubber, which can easily swell in solvent oil and wrinkle easily), while the wrinkle gloves such as nitrile, PU and butyl On the other hand, there are few reports and there are no such products in the market
The reason may be that nitrile, PU, ​​and butyl latex are a kind of latex with high polarity. The rubber formed after curing has excellent wear resistance, water resistance, oil resistance and chemical corrosion resistance. Good corrosion resistance, it is difficult to swell it with solvents, and it is often impossible to create lines on its surface; but the surface of nitrile rubber is relatively flat and smooth, and it becomes smoother when it meets water or oil, which leads to the application function of nitrile gloves Restricted
And at the same time, the natural latex wrinkled gloves sold on the market are not ideal in terms of wear resistance and use, and because the oil resistance of natural latex gloves is very poor, it is not suitable for professional use in organic solvents such as oil fields and auto repairs. The field is very limited; moreover, the currently used wrinkled gloves mostly use organic solvents such as xylene, acetic acid, etc. to make the surface wrinkle, the production process has a strong smell, and there are hidden dangers to the health of the workers in the production workshop, which is not environmentally friendly

[0035] The present embodiment provides a preparation method of natural latex wrinkled gloves, comprising the steps of:

[0036] Step S1: adding 1.2 parts of sodium polyacrylate to 100 parts by weight of pre-vulcanized natural latex to obtain a dope with a viscosity of 3000 mPa.s.

[0037]Step S2: Immerse the 13-needle polyester knitted glove embryo in a 2% calcium nitrate methanol solution at a temperature of 50° C. After immersing the solid agent, immerse it in the glue prepared in step S1, take it out, and spray it with powder The device sprays casein on the surface of the glove embryo, the spraying time is 10s, and is concentrated on the fingers and the palm of the palm surface of the glove.

[0038] Step S3: pre-vulcanization and drying at 70° C. for 40 minutes, and then rinsed with water.

[0039] Step S4: first vulcanizing and drying at 75°C for 40 minutes, then vulcanizing and drying at 110°C for 70 minutes, after the drying is completed, the gloves are taken out of th...

Embodiment 2

[0041] The present embodiment provides a preparation method of nitrile wrinkled gloves, which comprises the steps:

[0042] Step S1: adding 0.8 part of casein to 100 parts by weight of pre-vulcanized nitrile latex to obtain a dope with a viscosity of 3500 mPa.s.

[0043] Step S2: Preheat the flannel glove embryo to 30°C, immerse it in the glue prepared in step S1, and after taking it out, use a powder sprayer to spray polyacrylic acid powder on the surface of the glove embryo, the spraying time is 20s, and focus on the palm of the glove. face side.

[0044] Step S3: pre-vulcanization and drying at 75° C. for 40 minutes, and then rinsed with water.

[0045] Step S4: first vulcanizing and drying at 80° C. for 30 minutes, then vulcanizing and drying at 120° C. for 60 minutes, after the drying, the gloves are taken out of the drying box, and the gloves are removed from the hand mold to obtain nitrile wrinkled gloves. The wrinkles on the surface of the glove make the glove non-sl...

Embodiment 3

[0048] The present embodiment provides a preparation method of butyl wrinkle gloves, which comprises the steps:

[0049] Step S1: adding 2.5 parts of 2% CMC to 100 parts by weight of pre-vulcanized butyl latex to obtain a dope with a viscosity of 4000 mPa.s.

[0050] Step S2: Preheat the flannel glove embryo to 30°C, immerse it in the glue prepared in step S1, take it out, use a powder sprayer to spray PVP powder on the surface of the glove embryo, the spraying time is 15s, and focus on the palm surface of the glove side.

[0051] Step S3: pre-vulcanizing and drying at 60° C. for 50 minutes, then washing with water, and the PVP in water can be recovered. Step S4: first vulcanizing and drying at 80° C. for 30 minutes, then vulcanizing and drying at 120° C. for 65 minutes, after the drying, the gloves are taken out of the drying box, and the gloves are removed from the hand mold to obtain butyl wrinkle gloves. The wrinkles on the surface of the glove make the glove non-slip an...

Abstract

The invention relates to a preparation method of wrinkle gloves. The preparation method of the wrinkle gloves comprises the steps of S1, preparing a rubber cement: adding a thickening agent to rubberlatex, and preparing the rubber latex into the rubber cement with viscosity of 1200-7500 Pa.s; S2, impregnating in rubber: impregnating glove blanks, which are pre-treated or not pre-treated, in the rubber cement; and after the glove blanks are taken out, using a spraying device to spray particulate matters to the rubber cement on the surfaces of the glove blanks, wherein the particulate matters are water-absorbent resin powder particles; S3, prevulcanizing and water washing: prevulcanizing and drying the glove blanks, and then carrying out water washing on the glove blanks to remove non-bonded particulate matters; and S4, vulcanizing and drying: vulcanizing and drying the glove blanks at a low temperature first, and then vulcanizing and drying the glove blanks at a high temperature to prepare the wrinkle gloves. The preparation method of the wrinkle gloves is used. The preparation method of the wrinkle gloves, provided by the invention, has the advantages that an existing oiling agentswelling mode is changed into a mode of spraying resin particles to realize wrinkling, the application range of a rubber glove wrinkling process is expanded, swelling solvents such as xylene and acetic acid are not needed, irritating odor and organic waste water are not generated, and therefore, the preparation method of the wrinkle gloves is very environmentally friendly.

Description

technical field [0001] The invention relates to a manufacturing process of gloves, in particular to a preparation method of gloves with wrinkles on the surface. Background technique [0002] The preparation method of rubber gloves is generally to form a layer of rubber layer by impregnating the surface of the textile glove embryo with natural latex, synthetic latex, etc., and then solidifying to form a layer of rubber, which plays the role of hand protection. In order to improve the grip performance of the glove, it is necessary to form beads or wrinkles on the surface of the glove to increase the coefficient of friction. [0003] At present, most wrinkled gloves on the market are wrinkled gloves of natural latex (natural rubber is non-polar rubber, which can easily swell in solvent oil and wrinkle easily), while nitrile, PU and butyl gloves are wrinkled. On the one hand, there are almost no reports, and there is no such product in the market. The reason may be that nitril...
