Problems solved by technology

Phthalate plasticizers are the most widely used and used in the largest amount, but if the plasticizer is used in PVC products, the migration will damage the endocrine system of the human body, which can cause changes in the hormone system and lead to Reproductive development problems, especially the growth and development of infants and young children have a greater adverse effect

Embodiment 1

[0022] An environment-friendly soft PVC plasticizer is composed of the following components in parts by weight:

[0023] 60 parts of cage silicone hybrid star polyester;

[0024] 20 parts of fatty acid methyl ester;

[0025] 25 parts of epoxy fatty acid methyl ester;

[0026] 5 parts of benzoic acid;

[0027] 5 parts of ethylene glycol;

[0028] 4 parts of carbonamide;

[0029] 7 parts of soluble polyvinyl alcohol;

[0030] 4 parts of epoxidized soybean oil.

[0031] The cage-type organosilicon hybrid star polyester is prepared by the following method: (1) ricinoleic acid is sequentially cleaved and oxidized by ozone oxidation, and Pd / C catalyzed hydrogenation reaction to obtain nonanol acid and 1,3- Mixed product of dihydroxynonanediol; (2) The vertex group of octamethacryloxypropyl cage silsesquioxane undergoes ester hydrolysis reaction in aqueous sulfuric acid solution, stirring and refluxing for 4 hours to obtain octapropanol (3) the mixed product obtained in step (...

Embodiment 2

[0034] The composition of this embodiment is the same as that of Example 1, except that the environment-friendly soft PVC plasticizer is composed of the following components in parts by weight:

[0035] 65 parts of cage silicone hybrid star polyester;

[0036] 20 parts of fatty acid methyl ester;

[0037] 25 parts of epoxy fatty acid methyl ester;

[0038] 5 parts of benzoic acid;

[0039] 5 parts of ethylene glycol;

[0040] 5 parts of carbonamide;

[0041] 7 parts of soluble polyvinyl alcohol;

[0042] 4 parts of epoxidized soybean oil.

[0043] After adding the above plasticizer, the plasticizing time of PVC is 1.1 minutes, the plasticizing is easy, the plasticizing performance is good, and the plasticizing efficiency is high.

Embodiment 3

[0045] The composition of this embodiment is the same as that of Example 1, except that the environment-friendly soft PVC plasticizer is composed of the following components in parts by weight:

[0046] 70 parts of cage silicone hybrid star polyester;

[0047] 20 parts of fatty acid methyl ester;

[0048] 25 parts of epoxy fatty acid methyl ester;

[0049] 5 parts of benzoic acid;

[0050] 5 parts of ethylene glycol;

[0051] 4 parts of carbonamide;

[0052] 7 parts of soluble polyvinyl alcohol;

[0053] 4 parts of epoxidized soybean oil.

[0054] After adding the above plasticizer, the plasticizing time of PVC is 1.0 minute, the plasticizing is easy, the plasticizing performance is good, and the plasticizing efficiency is high.

Abstract

The invention relates to the technical field of functional polymer material preparing and modifying, in particular to an environment-friendly soft PVC plasticizer. The plasticizer is prepared from, by weight, 60 parts to 70 parts of cage-type organosilicon hybridization star-type polyester, 10 parts to 20 parts of fatty acid methyl ester, 20 parts to 25 parts of epoxidized fatty acid methyl ester, 5 parts to 8 parts of benzoic acid, 5 parts to 8 parts of ethanediol, 3 parts to 5 parts of carbamide, 5 parts to 8 parts of dissolubility polyving akohol and 2 parts to 6 parts of epoxidized soybean oil. The plasticizer is nontoxic and environmentally friendly, and has the advantages of being free of volatility and mobility and good in PVC compatibility and durability.

Description

technical field [0001] The invention relates to the technical field of preparation and modification of functional polymer materials, in particular to an environment-friendly soft PVC plasticizer. Background technique [0002] Plasticizers refer to organic substances that increase the plasticity of plastics, improve the fluidity of resins during plastic processing, and make plastic products flexible. Plasticizers are usually viscous liquids with high boiling points, difficult to volatilize or solids with low melting points. Plasticizers are generally required to be colorless, non-toxic, odorless, cold-resistant, heat-resistant, volatile and mobile, and chemically Good stability, cheap and easy to get. Plasticizers can weaken the van der Waals force between plastic polymer molecules, increase the mobility of polymer molecular chains, reduce the crystallinity of polymer molecular chains, and enhance the plasticity of polymers, thereby reducing the hardness and softening temper...
