Abstract
The invention discloses a kind of preparation method of environment-friendly type rosin solution, this method uses plasticizer trimellitate, citric acid three ester or epoxidised fats for solvent, in 80~90 DEG C of stirring and dissolving rosin, obtains the rosin solution；And safety and environmental protection, non-toxic and tasteless, hardly possible volatilization.Meanwhile used solvent has the function of plasticising and wetting action, its minimum film formation temperature of latex and glass transition temperature after making compounding all reduce, and the flexibility of glue film and flexibility all improve, so that the wetability and stickup property to non-polar material are greatly improved.So the rosin solution that solvent selected by the present invention is prepared into, had not only had the function of the feature of environmental protection but also had had plasticising concurrently, it is the functional environment-friendly type rosin solution for being conducive to latex and compounding being blended.
Description
Technical field
The invention belongs to bonding technique fields, and in particular to a kind of preparation method of environment-friendly type rosin solution.
Background technique
Rosin is the non-volatile natural resin that is obtained by different processing methods using pine resin as raw material.Rosin
It is important industrial chemicals, is widely used in the rows such as soap, papermaking, paint, ink, rubber, adhesive, electrical, food
Industry.In recent years, application of the rosin in bonding technique field increases year by year.In being compounded with the blending of environmental-friendly water-base latex,
Obtain latex modified to have better adhesivity and tack, to non-polar material such as bidirectional stretching polypropylene film
BOPP, polyvinylchloride skin or PVC film (hard, semi-rigid, soft) and polyethylene film PE and timber, paper, foam system
There is good effect in the stickup of the materials such as product.But rosin is solid, cannot directly be used in adhesive, it is necessary to be prepared
At solution or lotion.Usually rosin and caustic soda are carried out saponification or rosin are emulsifiable in water with emulsifier rosin cream is made
Liquid.But rosin milk has the shortcomings that rosin content is too low, the adhesive property decline of lotion unstable easy deposition, rosin, with
Latex compounding intermiscibility and compounding after adhesive effect it is all bad.Therefore, rosin is usually prepared into solution and latex carries out
Compounding is blended.Preparing the most common solvent of rosin solution has toluene, ethyl alcohol, acetone, dimethylbenzene, turpentine oil, also useful gasoline, chlorine
Solvent is used as hydrocarbon, ethers, acetate esters etc..But these organic solvents have the shortcomings that following one or more: (1) toxic, poison
Evil health；(2) inflammable and explosive safety problem；(3) limited to the solvability of rosin；(4) volatile, a large amount of uses cause ring
Guarantor's problem；(5) there is niff.Therefore, it is necessary to be improved to the preparation method of current rosin solution, to reach peace
The purpose that loopful is protected.
Summary of the invention
The shortcomings that present invention is exactly directed to current rosin solution preparation method is improved, and a kind of environment-friendly type rosin is provided
The preparation method of solution.
The present invention adopts the following technical scheme: a kind of preparation method of environment-friendly type rosin solution, using trimellitate, lemon
One or more of three esters of lemon acid, epoxidised fats obtain the rosin in 80~90 DEG C of stirring and dissolving rosin for solvent
Solution.
Further, the mass percent of solute rosin is 20%~50%.
Further, the trimellitate, including but not limited to tri trimellitate be pungent/last of the ten Heavenly stems ester, tri trimellitate
Monooctyl ester, tri trimellitate nonyl ester.
Further, the citric acid three ester, including but not limited to tributyl citrate, trioctyl lemon acid, second
Acyl tributyl citrate, acetyl tributyl citrate.
Further, the epoxidised fats, including but not limited to epoxidized soybean oil, epoxy acetylricinoleate oleic acid first
Ester, nontoxic plasticizer acid butyl ester, ethyl hexyl ester of epoxidized soybean oil, epoxy silkworm chrysalis butyl oleate.
The beneficial effects of the present invention are: trimellitate, citric acid three ester, epoxidised fats are common plasticizer,
Inventor in experiments it is found that, there is fabulous solubility property to rosin with above-mentioned plasticizer, and safety and environmental protection is non-toxic and tasteless,
Hardly possible volatilization.Meanwhile used solvent has the function of plasticising and wetting action, its minimum film formation temperature of latex and glass after making compounding
Glass temperature all reduces, and the flexibility of glue film and flexibility all improve, thus the wetability to non-polar material and stickup property
It is greatly improved.So the rosin solution that solvent selected by the present invention is prepared into, had not only had the feature of environmental protection but also had had plasticising function concurrently
Can, it is the functional environment-friendly type rosin solution for being conducive to latex and compounding being blended.
