Problems solved by technology

Although the aforementioned two patents can obtain thinner silicone rubber thin products, the process of the former is cumbersome and requires a cloth to work; the latter patent will leave fabrics (such as glass fiber) in the finished product. The finished product obtained is not a pure silicone rubber thin product, and the process used in both will increase the production cost

Embodiment Construction

[0024] The present invention is a calendering production method of lipophilic rubber thin products, which can continuously produce thin products with a uniform thickness by a calender, and the thickness can be less than 0.5mm (the minimum thickness is 0.05mm), and the width can reach more than 800mm. Using the present invention The production method can make thin products easier and less costly in the production process.

[0025] like figure 1 Shown, the production flowchart of the present invention, its steps are as follows:

[0026] In step 101, the lipophilic rubber raw materials are mixed according to the relevant formula and then put into the calender.

[0027] In step 102, when the raw material is sequentially rolled by multiple rollers in the calender, the circumferential surface of each roller is kept in a dew condensation state.

[0028] In step 103, a continuous wide lipophilic rubber thin product can be formed finally.

[0029] In addition, in step 102, according...

Abstract

The invention relates to a method for calendaring and producing a thin rubber product with special design by using the physical property of synthetic rubber. The method comprises the following steps: placing a rubber material in a calendar; calendaring the material through a plurality of rollers in sequence; and directly producing the wide thin rubber product, with thickness below 0.5mm in the calendaring manner. In order to keep the surfaces of the rollers in better condensation state in the calendaring process, the surfaces of the rollers are adjusted to different temperature according the property and the condition of the lipophilic rubber material, so as to obtain the continuous wide thin rubber product. Since the lipophilic rubber material further comprises silicone rubber, chloroprene rubber, etc, through the method, the wide thin rubber product with thickness below 0.5mm can be directly produced in the calendaring manner, the thickness error of the product is small and the production cost is also reduced.

Description

technical field [0001] The invention relates to a calendering production technology of lipophilic rubber products, in particular to a calendering production method capable of directly producing thinner and wider lipophilic rubber thin products with a calender. Background technique [0002] Silicone rubber (silicone) is a non-toxic material with excellent weather resistance, cold resistance and heat resistance. It is widely used in industry, civil, medical and military fields. The traditional methods of manufacturing silicone rubber thin products are mainly molding and calendering. The size of the silicone rubber sheet (sheet) produced by the molding process is limited by the shape of the mold itself, and it is produced sequentially in a single piece, so it cannot be produced Continuous sheet; in addition, the thickness tolerance of the products produced by molding is larger, and the tolerance of the finished products produced by the calendering process is also larger. Altho...
