Vegetable oil soap foot is used as the base component to give pressure sensitive tape flexibility

Vegetable oil soap foot is used as the base component to give pressure-sensitive tape flexibility.

Existing pressure-sensitive adhesive is generally made into tape form. One side of the tape is not suitable for the application of two sides of paste, double-sided tape is more troublesome to use, not easy to tear at any time, and the adhesive layer of the tape is thin, the base material can not be recovered after cutting, difficult to reuse. On the other hand, the rubber belt with expensive flexible polymer as the basic component to give the product flexibility, its dosage is usually up to 30~50% of the total weight, and the need for special manufacturing equipment, so its production investment and product cost is high.

Now we break through the above limitations of pressure-sensitive tape and provide a new pressure-sensitive adhesive in a soft solid form that can be widely used for pasting and fixing between a variety of ash-free dry surfaces. It is easy to use and can be reused many times. On the other hand, the invention uses advanced fatty acid polyvalent metal soap such as advanced fatty acid aluminum or its crosslinked products as the basic components to give the product flexibility. Therefore, cheap raw materials can be used instead of expensive rubber flexible polymers (the amount does not exceed 5% of the total weight), and the production equipment required by the invention is simple, and can be produced by ordinary heating, bumping, and mixing.

So the purpose of this paper is to provide a simple and easy way to use vegetable oil soap foot. Many vegetable oils, such as cottonseed oil and rapeseed oil, produce a kind of waste containing a lot of high fatty acids in the alkali refining process. At present, the utilization of this waste is not enough. The main ways of utilization are to make low-grade soap and extract fatty acids. It is difficult for the waste to be processed locally by township enterprises, which limits the use of the mound, making it overstocked in some areas and becoming a source of pollution.
