Problems solved by technology

Due to the uncontrollability of the grinding effect and process, and the difference between the water-soluble color paste purchased in the market, the type, type, and pH value of the surfactant contained in the market, and the rubber latex raw material and rubber latex compounding agent, the impact on the rubber latex chemical stability
During color filling, the color paste supplier instructed that the color paste should be diluted to 25%. Traditionally, the color paste is also filled according to the law. There are no clear requirements for the dilution concentration, pH value, temperature, and batching speed of the color paste, which will affect the rubber latex brown. stability of movement
During production, the viscosity of rubber latex increases and grains form, resulting in defects such as color difference, graining, gelling, and pinholes in the product, resulting in a large amount of product loss and waste of resources.

Embodiment 1

[0060] see figure 1 , the present invention discloses a preparation process of rubber surgical gloves which are obviously different from human tissue, and the preparation process comprises the following steps:

[0061] [Step S1] Use deionized water to adjust the concentration of the water-soluble color paste to 10% (referring to the solid content of the water-based color paste).

[0062] [Step S2] Use caustic potash solution to adjust the pH value of the prepared water-soluble color paste so that the pH value differs from the pH value of the rubber latex by plus or minus 0.2.

[0063] 【Step S3】Adjust the temperature of the diluted water-soluble color paste. The color of the color paste is royal blue or brown or green. Model: GP1503, the same below), the brown color interval is "4635U, 4705U, 478U" interval, the green color interval is "3245U, 3248U, 3255U" interval; the temperature is adjusted to the temperature of plus or minus 1°C with the rubber latex; The rubber latex i...

Embodiment 2

[0077] see figure 2 The difference between the present invention and Embodiment 1 is that in this embodiment, the preparation process also includes the production process of rubber surgical glove packaging bags, and the packaging bag production process includes the following steps:

[0078] [Step S1] Use the vacuum suction generated by the vacuum pump to first pass the heated and softened HDPE / PE lower film through the mold at an appropriate temperature and pressure for design verification to form the cavity required for the design.

[0079] The base film to be blister-formed is sent to the packaging machine through a conveyor belt controlled by variable speed. When it runs to the position of the forming cavity, the formed HDPE / PE base film is heated at a set temperature of 90-120°C, and the vacuum pressure is 0.6-0.8 Under the condition of Mpa, the vacuum suction generated by the vacuum pump is used to first heat and soften the HDPE / PE bottom film through the mold to form th...

Embodiment 3

[0126] The present invention discloses a production equipment for the packaging bag corresponding to the preparation process of the rubber surgical glove packaging bag in the second embodiment. The production equipment includes: a first vacuum system 1, a second vacuum system 2, a variable speed control transmission system 3, Waste edge collection system 4, vertical and horizontal cutting system 5, film unwinding mechanism 6, photoelectric eye sensor system 7, heating and sealing system 8, PLC control system 9, rubber surgical glove placement system 10, heating and blister forming system 11, film Unwinding mechanism 12; each system is uniformly controlled by PLC control system 9.

[0127] The film unwinding mechanism 6 and 12 are used to unwind the film and keep it tensioned; the film unwinding mechanism includes a roller, an axial adjustment handwheel, an axial locking flange, a rocker arm, an unwinding cylinder and a brake mechanism; the film is put on the roller After the c...

Abstract

The invention discloses a preparation process of rubber surgical gloves distinctly different from human tissue. The preparation process comprises the following steps: 1, adjusting the concentration of water-soluble color paste to be 10% by using deionized water; 2, adjusting the pH value of the adjusted and blended water-soluble color paste by using a potassium hydroxide solution, thereby enabling difference of the pH value of the water-soluble color paste to be + / -0.2 different from that of rubber latex; and 3, adjusting the temperature of the diluted water-soluble color paste, that is, adjusting the temperature to be + / -1 DEG C different from that of rubber latex, slowly stirring rubber latex, and adding the water-soluble color paste from the bottom of rubber latex at the quantitative titration pump speed of 10kg per minute. By adopting the preparation process of rubber surgical gloves distinctly different from human tissue, stable Brownian movement, stable chemical stability, stable viscosity and uniform color can be achieved, flaws such as particle agglomeration, rubber agglomeration, color difference and pinholes of a product can be greatly reduced in production, the production efficiency can be improved, and the resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of rubber product preparation, and relates to a preparation process of rubber gloves, in particular to a preparation process of rubber surgical gloves which are obviously different from human tissues. Background technique [0002] At present, the sterilized rubber surgical gloves worn by medical personnel are the natural color of rubber raw materials. After batching, aging, sulfuration, chlorination, packaging, and sterilization, the finished product is generally white to light yellow. [0003] Surgeons wearing surgical gloves often need to cooperate with multiple people, use a variety of surgical instruments, and coordinate operations; the color of traditional surgical gloves and the color of the tissue of the patient being operated and the surgical instruments are difficult to identify under the lighting environment of the operating room. There is a risk of misuse by doctors, injury to doctors, medical sta...
