Abstract

The invention provides a low-toxic plasticizer, and relates to the technical field of additives. The low-toxicity plasticizer is prepared from the following components: 20 to 35 parts of phthalic anhydride, 12 to 26 parts of 2-propylheptanol, 8 to 16 parts of filler, 3 to 10 parts of a thickening agent, 11 to 18 parts of triethylhexyl phosphoric acid, 1 to 5 parts of methyl amyl alcohol, 4 to 9 parts of a cellulose derivative, 5 to 13 parts of guar gum, 14 to 23 parts of sodium polyacrylate and 2 to 8 parts of plant extractant, wherein the filler comprises ripple filler, grid filler, pall ring filler and cascade ring filler; the mass ratio of the ripple filler to the grid filler to the pall ring filler to the cascade ring filler is (3 to 11) : (2.5 to 5.5) : (2 to 9) : (4.7 to 12.6). The low-toxicity plasticizer provided by the invention has the beneficial effects that the plasticizing effect is good and the environment-friendly effect is good; the plant extract is added into the components of the plasticizer, so that the flexibility of the plasticizer can be improved, and the plasticizer meets green, organic and pure natural idea.

Description

technical field [0001] The invention relates to the technical field of additives, in particular to a low-toxicity plasticizer. Background technique [0002] Plasticizer (plasticizer) is a kind of polymer material additive, and it is also a phthalate (PAEsphthalates) in environmental estrogen. There are many kinds, the most common variety is DEHP (commercial name DOP), DEHP chemical name Bis(2-ethylhexyl)phthalate is a colorless, odorless liquid widely used in industry. Plasticizers, also known as plasticizers in general, are polymer material additives widely used in industry. Adding this kind of substance in plastic processing can make it more flexible, easy to process, and can be used legally Industrial applications. Plasticizers are bulk industrial products and are widely used in various fields of the national economy, including thousands of products such as plastics, rubber, adhesives, cellulose, resins, medical devices, and cables. However, most of the plasticizers cu...
