Abstract

The invention relates to the technical field of sheets and particularly relates to an acid and alkali resistant lace embossing polyvinyl chloride sheet and a preparation method thereof. The acid and alkali resistant lace embossing polyvinyl chloride sheet is prepared from the following raw materials in parts by weight: 40-60 parts of PVC resin, 40-60 parts of a filling agent, 10-14 parts of biological lipid, 10-14 parts of a plasticizer, 1-3 parts of a thermal stabilizer and 0.01-0.15 part of pigment powder, wherein the biological grease is a mixture of vegetable oil and animal fat in a weight ratio of (2-3) to 1, and the vegetable oil is a mixture of castor seed oil, rapeseed oil and soybean oil in a weight ratio of 1 to (1.5-2.5) to (1.6-2.4). By strictly controlling the weight ratio of the raw materials, the sheet is good in acid and alkali resistance, heat-resistant, cold-resistant, acid-resistant, heavy pressure-resistant, anti-ageing, anti-static, smooth in surface, free of cracks and gas bubbles, uniform in color, strong in third dimension, soft in texture, comfortable in hand feeling, healthy and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of sheets, in particular to an acid and alkali-resistant lace embossed polyvinyl chloride sheet and a preparation method thereof. Background technique [0002] Soft polyvinyl chloride sheet is transparent, beautiful and soft, and has been widely used in the field of daily products, such as tablecloths, table mats and placemats. This type of product is generally attached with a transparent film on the other side of the printed pattern. When it is covered on furniture, especially glass furniture, it can not only display the printed pattern on the transparent film, but also observe the shape of the furniture through the transparent film. Play a very good decorative effect. The existing sheet material has poor acid and alkali resistance and short service life. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to ...
