Embodiment Construction

[0014] A polyvinyl chloride laminated soft board, which is made of the following raw materials in the weight ratio,

[0015] PVC resin 90~110, calcium carbonate 15~20,

[0016] Plasticizer 30~40, tribasic flow acid copper 3~4,

[0017] Paraffin 10-12.

[0018] The preparation technology of polyvinyl chloride laminated soft board of the present invention,

[0019] Add the raw materials prepared according to the formula into the running high-speed kneader, and knead for 5-10 minutes. When the temperature of the material reaches about 140°C, send the material to the internal mixer for internal mixing. When the temperature of the material reaches 150°C At ~160°C, the material discharged from the internal mixer is sent to the first open plastic refining machine for mixing and plasticizing. The temperature of the plastic refining machine is generally controlled at about 150°C. During operation, care should be taken to turn over the material repeatedly , so that the plasticization...

Abstract

A polyvinyl chloride (PVC) laminated soft sheet is prepared by the following raw materials by weight ratio: 90-110 of PVC resins, 15-20 of calcium carbonate, 30-40 of plasticizers, 3-4 of tribasic copper sulfate and 10-12 of paraffins. The laminated soft sheet is prepared by low toxic materials, has similar properties with the extrusion soft sheets, is widely used as a waterproof and anticorrosive material and can be also used as a flooring material. The laminated soft sheet has the following advantages: the sheet quality is superior to that of the extrusion soft sheets, and the laminated soft sheet can also use the recycled materials or reclaimed materials as the inner layer to lower the cost. The length specification of the laminated products is often limited by the size of the press.

Description

technical field [0001] The invention relates to a waterproof and anti-corrosion material, especially a polyvinyl chloride laminated soft board [0002] The invention also relates to a preparation process of the polyvinyl chloride laminated soft board. Background technique [0003] PVC laminated soft board is made of PVC soft sheet with certain specifications after mixing PVC resin, calcium carbonate, plasticizer, stabilizer, lubricant and other raw materials according to the formula, and then according to the requirements of product thickness Select the sheets, stack them and then send them into the laminator, form them by hot pressing, cool and shape them into PVC laminated soft boards. The polyvinyl chloride laminated flexible board in the prior art contains lead-like toxic substances, which will affect human life safety. Contents of the invention [0004] The technical problem to be solved by the present invention is to propose a safe polyvinyl chloride laminated soft...
