The forming sheet is directly led into baking equipment, so that the forming sheet does not need to be preheated when entering the baking equipment, the surface temperature during extrusion forming is directly transited to 400 ℃ in an oven, the surface temperature of the forming sheet is within the range of 380-400 ℃ after baking is carried out for 8-12 seconds, then the forming sheet is quickly and directly led into spraying equipment to be sprayed with the abrasive material, the abrasive material can be stably adhered to the surface of the forming sheet, and the 360-DEG surface spraying effect is realized by adopting a plurality of spray heads; of course, any working temperature value of 380 to 420 degrees celsius can be selected according to different spraying requirements, and 380 degrees celsius, 390 degrees celsius, 420 degrees celsius and the like can be selected optionally. The spraying raw material adopted in the spraying process is a frosted material which is 0.2-05% of the silica gel raw material in parts, and the frosted effect on the surface of the lampshade can be effectively guaranteed.
Wherein, the mixing process comprises the following steps: starting a double-roller mixing device, and adding the silica gel raw material and the diffusion powder into the double-roller mixing device; adding a reinforcing filler, a structure control agent, a heat-resistant auxiliary agent and a coloring agent in the mixing process to obtain a rubber composite material; scraping the glue composite material on the movable rubber plate by using a scraper, and blanking the glue composite material after the glue composite material is subjected to thin-passing for 4 to 7 times; placing the rubber composite material for 12-18 hours, adding a heat-resistant auxiliary agent, adding a vulcanizing agent, thinly passing, placing for 2-4 days, and remilling to obtain the rubber composite sheet. The rotating speed ratio of the rollers of the double-roller mixing equipment is 1.2-1.5: 1, cooling water is introduced into the rollers, the mixing temperature is controlled within the range of 36-42 ℃, the distance between the two rollers is 1-5 mm when mixing starts, then the distance is gradually increased to a preset distance, and the mixing time is 20-40 minutes each time. The speed ratio of the roller of the double-roller mixing equipment is preferably 1.3: 1, the higher speed ratio leads to faster mixing after the roller is fast, and the low speed ratio can lead the rubber sheet to be smooth. The roller must be filled with cooling water, and the mixing temperature is preferably about 40 ℃ to prevent scorching or volatilization loss of vulcanizing agent. And (3) starting to reduce the roll spacing to 1-5 mm during mixing, and then gradually increasing. The feeding and operation sequence is as follows: raw rubber (wrapping roll), reinforcing filler, structure control agent, heat-resistant assistant, coloring agent, thinly passing for 5 times, blanking, oven heat treatment, remixing, vulcanizing agent, thinly passing, standing overnight, remixing and sheet discharging. The sizing material can also be subjected to heat treatment without an oven, after the heat-resistant auxiliary agent is added, the vulcanizing agent is added and then the sizing material is passed through thinly, placed overnight for remilling, and then placed for several days for remilling and sheet discharging for use. The mixing time is 20-40 min, the silicon rubber is added into a rubber mixing machine, a slow roller (front roller) is coated, a fast roller (back roller) is coated quickly during mixing, and two sides of the silicon rubber can be operated during rubber mixing. Because the silicon rubber material is softer, the silicon rubber material can be operated by a common putty knife during mixing, and the thin sheet can not be pulled down like common rubber but scraped by a steel, nylon or wear-resistant plastic scraper. In order to facilitate cleaning and prevent lubricating oil from leaking into the glue, a movable rubber plate is adopted.
