Description

Modified rosin resin

Technical field

The present invention relates to chemical technology field, especially a kind of Gum Rosin for the production of horse road marking paint.

Background technology

The modified rosin resin used in general production horse road marking paint process carries out addition reaction by rosin and cis-butenedioic anhydride or fumaric acid, conjugated double bond is disappeared, stable chemical nature, oxidation stain tendency lowers, esterification is carried out again with polyvalent alcohol, reduce the acid number of product, improve softening temperature, thus reach service requirements.But due to the oxidizable characteristic of rosin, horse road marking paint is easy to change also there is painting in actual production and application after, the problems such as poor fluidity.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of modified rosin resin, it can solve horse road marking paint actual production and application in there is painting after easy to change, the problem of poor fluidity.

In order to solve the problem, technical scheme of the present invention is:

The weight percent of this modified rosin resin constituent is: primary rosin 55%; Fumaric acid 10%; Glycerine 15%; Low iodine number lipid acid 19.85%; Anthraquinone 0.01%; Three (2,4-di-tert-butyl-phenyl) phosphorous acid ester 0.05%; 2,6 ditertiary butyl p cresol 0.05%; 4,4-bis-(a 6-tertiary butyl-tolyl) thiophenol 0.03%; Trisnonylphenyl phosphite 0.01%;

The weight percent of this modified rosin resin constituent is: primary rosin 60%; Fumaric acid 5%; Glycerine 24.82%; Low iodine number lipid acid 10%; Anthraquinone 0.05%; Three (2,4-di-tert-butyl-phenyl) phosphorous acid ester 0.02%; 2,6 ditertiary butyl p cresol 0.01%; 4,4-bis-(a 6-tertiary butyl-tolyl) thiophenol 0.05%; Trisnonylphenyl phosphite 0.05%.

Owing to adopting technique scheme, the present invention has following beneficial effect:

1, the present invention introduces low iodine number lipid acid Substitute For Partial rosin and carries out esterification, improves discolouration, increases resin to the wetting action of powder.

2, due to the introducing of low iodine number lipid acid, by increasing the amount of fumaric acid, addition reaction can be promoted, conjugated double bond thoroughly reacted, reduces oxidation stain further, solving after there is painting in application easy to change, the problems such as poor fluidity.

3,2,6 ditertiary butyl p cresol, the various antioxidant such as trisnonylphenyl phosphite, agent of losing lustre, adding of stablizer can make Gum Rosin tendency to oxidize in pyroreaction and product stock lower.

4, utilize the Gum Rosin of sustainable use to replace in horse road marking paint and day by day reduce petroleum resin, minimizing carbon emission amount, be conducive to environment protection.

Embodiment

By embodiment, the present invention is described in further detail below:

Embodiment 1--makes 4000 kilograms of modified rosin resins:

The raw material adopted: primary rosin 2200 kilograms; Fumaric acid 400 kilograms; Glycerine 600 kilograms; 794 kilograms, low iodine number lipid acid; Anthraquinone 0.4 kilogram; Three (2,4-di-tert-butyl-phenyl) phosphorous acid ester 2 kilograms; 2,6 ditertiary butyl p cresol 2 kilograms; 4,4-bis-(a 6-tertiary butyl-tolyl) thiophenol 1.2 kilograms; Trisnonylphenyl phosphite 0.4 kilogram.
