The production of plastic pads is complex and involves many steps. Although the produced plastic pads are flexible, they feel sticky. After a period of use, they will appear whitening when bent, the elasticity will deteriorate, and the life of the pad will be shortened; The structure of the mold used in pad production is complex and heavy. The original mold is three-piece and needs to be trimmed on both sides. During production and processing, it takes a long time to preheat the electric heating tube, consumes a lot of power, and requires a lot of labor resources to produce it. Each product is too simple in the final quality inspection, which greatly reduces the quality of the final product

Embodiment Construction
[0031] A kind of production technology of silica gel pad, it is characterized in that: comprise the following steps:
[0032] Step 1, the first heat press: hot press the first silicone layer on the back of the fabric to obtain a semi-finished silicone pad; during hot pressing, solid glue can be injected on the back of the fabric and then hot pressed or liquid silicone can be injected through the AB mixer On the back of the fabric and then hot press, the temperature is best controlled at 120°C during hot pressing;
[0033] Step 2. Punching edge material: Punch out the desired shape of the semi-finished silicone pad; when punching, the silicone edge and the cloth edge of the semi-finished silicone pad are punched at the same time;
[0034] Step 3, the second hot pressing: heat-press the second silica gel layer through the mold on the front of the die-cut semi-finished silica gel pad, and make the second silica gel layer cover the side of the semi-finished silica gel pad; it is b...

Abstract
The invention relates to the technical field of silicone pad production, in particular to a production process for a silicone pad. The production process comprises a cloth layer, a first silicone layer and a second silicone layer, wherein the first silicone layer and the second silicone layer are correspondingly arranged on the back side and the front side of the cloth layer. The production process comprises the following steps of firstly, primary hot pressing, secondly, scrap edge punching, thirdly, secondary hot pressing and fourthly, material taking. In the step of secondary hot pressing, grooves of a lower die plate can be sucked by silicone on the back side in the hot pressing process, the semi-finished silicone pad cannot move, the precision is made to be higher when the second silicone layer is hot-pressed, the flatness is optimum, and the edge of the semi-finished silicone pad is soft and not likely to be worn and damaged. The production process is simple, reasonable and environmentally-friendly, and the silicone has softness, is non-toxic, tasteless, resistant to strong acid and strong alkali and resistant to high temperature and is the best material for the production of pads, and the produced silicone pad is good in elasticity, good in hand feeling, optimum in flatness, not likely to be bent and deformed and not likely to be damaged and is popular among existing public customers.
Description
technical field [0001] The invention relates to the technical field of silica gel pad production, in particular to a production process of the silica gel pad. Background technique [0002] Nowadays, the mats used to place hot food dishes on the dining table are generally made of plastic. Most of these plastics are PVC materials, which are relatively heat-resistant. PVC is the only material that uses plasticizers in plastics, which makes its state change from soft and elastic to hard and brittle, especially the edges of plastic pads are more brittle and easy to wear, and they are often damaged from the edges. The production of plastic pads is complex and involves many steps. Although the plastic pads produced are flexible, they feel sticky. After a period of use, they will appear whitening when bent, the elasticity will deteriorate, and the life of the pad will be shortened; The structure of the mold used in pad production is complex and heavy. The original mold is three-pie...
