[0002] The production of rubber sheets is generally processed by a drum vulcanizing machine. In the production process, a calender is generally required. The size of the rubber sheet is relatively large. The width of the rubber sheet is generally 800-2000mm, and the length can reach ten or even tens of meters. This method is suitable For mass production, if the production quantity is small or the size is small, this method not only wastes a lot of money, but also has a large investment, and the product thickness consistency is not very good; if the mold processing method is used, the quantity is small and uneconomical. Heavy weight, labor-intensive production process

Abstract
The invention provides a method for manufacturing a small rubber sheet. The method comprises the following steps that: 1, a sharper frame is manufactured, the size and the thickness of the frame are determined according to the shape of a required product; 2, the rubber semi-finished product is placed in the frame, the upper surface and the lower surface of the frame are coated by a 0.8 to 1.5mm cold-reduced sheet or a 0.8 to 1.5mm galvanized sheet, the coated frame passes through a vulcanizing machine at a pressure of between 3 and 20MPa and a temperature of between 120 and 200 DEG C for 3 to 20 minutes; and 3, after cooling, the frame is taken out and put in a clean placement area at normal temperature. The rubber sheet manufactured by the method has stable thickness, smooth surface and cost saving.
Description
technical field [0001] The invention relates to a manufacturing method of a rubber rubber sheet, in particular to a manufacturing method of a small-sized rubber rubber sheet. Background technique [0002] The production of rubber sheets is generally processed by a drum vulcanizing machine. In the production process, a calender is generally required. The size of the rubber sheet is relatively large. The width of the rubber sheet is generally 800-2000mm, and the length can reach ten or even tens of meters. This method is suitable For mass production, if the production quantity is small or the size is small, this method not only wastes a lot of money, but also has a large investment, and the product thickness consistency is not very good; if the mold processing method is used, the quantity is small and uneconomical. The weight is large, and the production process is labor-intensive. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentio...
