Abstract
The invention discloses a non-toxic plasticizer of biomass compound epoxy fatty acid methyl ester used in plastics and rubbers processing, which can be represented by the general formula I, wherein R, R' are CnH2n +1 (n = 0~15). The nontoxic plasticizer is prepared with fatty acid methyl ester as raw material, hydrogen peroxide as oxygen body, organic acid as oxygen-carrier, acidic matter as catalyst, and complex as stabilizer through epoxidation. The plasticizer not only has the advantages of excellent toughness, good compatibility, low volatile, small migration, non-toxic, and light and heat stability, but also has superior lubricity, compatibility and dispersibility. It can be used in PVC processing with addition of as many as 5-30%, completely replacing DOP to manufacture nontoxic PVC products for food packaging, medical supplies materials, toys, water supply pipeline, and surfactant, softening agent and dispersing agent used in plastics and rubber industries.
Description
One, technical field
The present invention relates to organic chemical industry's product, particularly the biomass epoxy compounds.
Two, background technology
In organic chemical industry's industry,, need to add a certain proportion of softening agent in order to improve the processing characteristics of plastics, rubber.Generally use phthalic ester plasticizer at present, as DOP (dioctyl phthalate (DOP)), because of it contains aromatic nucleus, readily biodegradable not, and poisonous, belong to non-renewable petrochemicals again, use range is subjected to bigger restriction.Domestic existing many non-toxic plasticizer researchs and the relevant report of producing, as with soybean oil, Oleum Gossypii semen, Rice pollard oil, rapeseed oil, flax wet goods vegetables oil as raw material, obtain a kind of nontoxic, tasteless epoxidized vegetable oil through epoxidation production, as the softening agent thermo-stabilizer of holding concurrently, light and heat had the satisfactory stability effect.But there is following problem in they: 1. relatively poor with plastics such as PVC (polyvinyl chloride) consistency, must with phthalate such as the composite use of DOP, could produce better action, that is can only be as the secondary softening agent of PVC, generally in polyvinyl chloride resin, add 1-3%, to bring poisonous of phthalic ester plasticizer and be difficult for biodegradable problem, can only play and alleviate effect and can not fundamentally solve; 2. with vegetables oil as raw material, production cost is higher.Agricultural science and technology net (the http://www.ahnw.gov.cn/2006nykj/Show.asp of Anhui Province? ContentID=%7B23E4B56C-76E1-4148-9A93-255COB6B97D8%7D) a kind of method of producing chloro methoxyl group fatty acid methyl ester with fatty acid methyl ester through the chloro methoxylation is disclosed, though as non-toxic plasticizer overcome and plastics between the relatively poor problem of consistency, but it is produced process need and uses chlorine in a large number, therefore environmental pollution is serious, large-scale industrial production not as yet.
Three, summary of the invention
The purpose of this invention is to provide a kind of nontoxic, readily biodegradable, and plastics and rubber between consistency is good, production cost is low biomass compound softening agent.
For realizing above purpose, the invention provides a kind of biomass compound epoxy aliphatic acid methyl ester, it is made of following general formula:
R, R ' are C in the formula
nH
2n+1, n=0-15.
Above-mentioned biomass compound epoxy aliphatic acid methyl ester is used for plastics and Rubber processing as non-toxic plasticizer.
Epoxidized vegetable oil such as soybean oil typical case molecular formula are C
57H
104O
9, its structural formula molecular formula general formula is:
And chloro methoxyl group fatty acid methyl ester typical component molecular formula is C
20H
38O
3Cl
2, its structural formula molecular formula general formula is:
Contrasting above three kinds of structural formula molecular formula general formulas can find, although epoxidized vegetable oil and epoxy aliphatic acid methyl ester all have epoxy group(ing), but epoxy aliphatic acid methyl ester is because of having polar group methoxycarbonyl and nonpolar chain alkyl, and its structural formula molecular formula and epoxidized vegetable oil are still had any different; And compare with chloro methoxyl group fatty acid methyl ester, because of the latter does not have epoxy group(ing), so both structural formula molecular formula have significant difference.
Because of epoxy aliphatic acid methyl ester has polar group methoxycarbonyl and epoxy group(ing)
Has nonpolar chain alkyl again, therefore make softening agent when at high temperature mixed mutually with it with polyvinyl chloride (PVC) resin isopolarity macromolecular material, plasticizer molecule is alternately between polymer molecular chain, partly attract each other by polarity and to form uniform and stable system, even temperature decline post-plasticization agent molecule also can be stayed between the polymer molecular chain, thereby show and polyvinyl chloride (PVC) resin isopolarity macromolecular material between consistency good, volatility is low, the characteristic that transport property is little, be used for the adding proportion that macromolecule material product adds man-hour thereby improved greatly, adding proportion is up to 5-30%, and it is nontoxic to replace the DOP softening agent to produce fully, degradable, the macromolecular material product of environmental protection; And that its long nonpolar moieties plays the barrier polymers molecular chain is approaching mutually, thereby weakens their gravitation, makes the polymkeric substance deliquescing, reaches plasticization effect.In addition, epoxy aliphatic acid methyl ester can absorb the hydrogenchloride of emitting when PVC decomposes, and light and heat is had the satisfactory stability effect, thereby polyvinyl chloride resin is played function of stabilizer.Therefore, epoxy aliphatic acid methyl ester be that a kind of ideal is nontoxic, degradable, environment-friendly type plastic and rubber plastizing agent and stablizer.
Compare with the epoxidized vegetable oil softening agent, the epoxy aliphatic acid methyl ester softening agent not only can replace the DOP softening agent to produce PVC product nontoxic, environmental protection fully, be used for food product pack, medical article material, toy and water supply line etc., simultaneously also as celluosic resin and elastomeric non-toxic plasticizer and tenderizer, in the processing of goods, adding epoxy aliphatic acid methyl ester can obviously improve physical properties of articles and prolong digestion time, with metal(lic)stabilizer and times spent such as barium, cadmium, zinc, good synergy is arranged.In addition, because of it also has good lubricity, consistency and dispersion performance, go back useful as surfactants and dispersion agent and be applied to production industries such as epoxy coating and Resins, epoxy.
According to the purposes of epoxy aliphatic acid methyl ester, its relevant physical and chemical index is as follows:
