Abstract

The invention discloses a nontoxic environment protection polyvinyl chloride sealing gel and a preparation method thereof. The gel is made of pvc paste resin, dioctyl phthalate, acetyl tri-n-butyl citrate, heavy calcium carbonate, calcium-zinc stabilizer, white foaming agent, titanium dioxide, dimethicone and rapeseed oil. Phthalic ester plasticizer is not comprised. The gel meets the requirements of the food safety, and corresponds with the RoHS instruction. The gel is a foot and environmental friendly sealing gel. The using amount of fillings is added. The production cost is lowered. The nontoxic and environmental friendly sealing gel has the advantages of low price, high temperature resistance, good sealing effect and convenient engagement.

Description

technical field [0001] The invention relates to a bottle cap sealant, in particular to a non-toxic and environment-friendly polyvinyl chloride bottle cap sealant and a preparation method thereof. Background technique [0002] Bottle cap sealant is indispensable for sealing various bottled products, but its production is currently controlled by a few companies, and the materials and manufacturing methods are kept secret, which almost controls the lifeblood of the industry's development. With the continuous development of science and technology, the requirements for PVC bottle cap sealants are getting higher and higher all over the world, not only requiring good sealing performance, but also requiring no pollution to food and the environment. However, the use of phthalates (such as DEHP) plasticizers used in traditional polyvinyl chloride bottle cap sealants has been proven to have certain damage to the human liver, and its use is limited. Therefore, seeking materials to repl...
