Abstract
Modified natural resin is prepared from vegetable oil and plant resin solid as material and through hot refining and dilution process. Unlike petrochemical resin, the modified natural resin has no toxic and harmful matter. The modified natural resin has relatively low production cost and its production process is simple.
Description
The present invention relates to a kind of resin, particularly relate to vegetables oil and vegetable solid resin be paint raw material being used to of making, modified natural resin that color spreading agent, tackiness agent, putty are made.
Traditional paint manufacturing starting material of resin, great majority are taken from petrochemicals.In their manufacturing processed, produce the residue that is difficult to break up degraded, become the industrial refuse that can not utilize again.Meanwhile, also discharge toxic gas, and then atmosphere pollution.Utilize the paint of this resin manufacture, continue contaminate environment, and bring out diseases such as the obstacle of respiratory system and cancer, human and environment are played utmost point deleterious effects.Utilize the vegetal resin of petroleum chemistry substance modification,, all have the problems referred to above as oil-based resin, Synolac etc.
The vegetal resin that has data record, someone to invent to contain wax and the paint of environment-friendly type thereof, the poisonous and harmful problem that has solved petroleum chemistry resin and paint product thereof and existed with the resin and the paint thereof of petroleum chemistry material modification.But the resin and the paint product thereof of this content of wax, it forms complicated, and operating procedure is loaded down with trivial details, some prices of raw and semifnished materials costliness, the manufacturing cost height is difficult to be accepted by market.
The object of the present invention is to provide a kind of is raw material with vegetables oil and vegetable solid resin, through heat refining, dilute prepared modified natural resin, both solved the poisonous and harmful problem that petroleum chemistry resin and paint product thereof exist, the vegetal resin that contains wax and the paint of environment-friendly type thereof have been solved again, the cost height, problem such as operating procedure is loaded down with trivial details.
The present invention realizes with the following methods:
Modified natural resin of the present invention, % counts by weight, and its proportioning is:
Oleum lini 20-30%
Tung oil 2.5-15%
Dammar gum 2.5-15%
Rosin glyceride 15-25%
Sweet orange oil 5-10%
Turps 25-35%
Modified natural resin of the present invention, its production technique are that oleum lini, tung oil, dammar gum, rosin glyceride are mixed, through the high temperature heat refining after the modified natural resin that sweet orange oil, terebinthine dilution are made.
The advantage of modified natural resin of the present invention is:
1, modified natural resin of the present invention is not to be raw material with the petrochemicals, and is that raw material is made with the vegetables oil that extracts in the natural phant, and is therefore not only harmless, free from environmental pollution again.
2, modified natural resin of the present invention, the residue that forms in its manufacturing processed all are organism, can both break up degraded voluntarily, can make animal feed.
3, modified natural resin of the present invention, its operating procedure is simple, and low cost of manufacture has good market outlook.
Below in conjunction with embodiment, the present invention will be described in more detail.
Siccative oil is to the ratio of hardened resin, the content of the siccative oil in the solid substance just, and promptly oil content has a significant impact film performance.
The experiment proved that, the resin of short oil, viscosity is big, so coating performance is bad, and bending property is poor, and but hardness, gloss, oil-proofness and tint retention are good, weather resisteant can be poor, long oil resin, brushing property, tack, snappiness, weather resisteant are good, but drying property, Waterproofing/oilproofing performance and gloss difference.The resin of medium-oil-length (45%-60%), not only its drying property is good, and other are as projects such as gloss, hardness, yellowing resistance and wrinkles, all is better than short, long oil resin.Along with coated article and environment of living in thereof, as the difference of conditions such as temperature, sunshine, the oil content that is suitable for is also different.
Character and their effect, the oil content in resin according to each key element change the material impact to film performance, and the invention process is as follows:
Adopt the resin of medium-oil-length (47%), i.e. rosin glyceride (A) and dammar gum (B) sum, proportion is 30% (weight ratio) in resin; Oleum lini (C) and tung oil (D) sum, proportion is 35% (weight ratio) in resin, turps (E) and sweet orange oil (F) proportion are 35% (weight ratio).
A, B, C, D, E, F as parameter, are analyzed the influence of resin and film performance thereof, have found out optimum implementation, its embodiment following (by weight):
Oleum lini (C): 25%
Tung oil (D): 10%
Rosin glyceride (A): 20%
Dammar gum (B): 10%
Turps (E): 30%
Sweet orange oil (F): 5%
A, B, C, D in said sequence and ratio, are mixed and stir, and the limit is blown into nitrogen then, the limit heat temperature raising.When temperature reaches 180 ℃, continue heating 1 hour, be cooled to 80 ℃ subsequently, add E and F, mix, be the finished product of modified natural resin of the present invention.
To finished product test, non-volatile part is 60 ± 5, and proportion is 1.02 ± 0.05.
Modified natural resin of the present invention, (optimum formula of fragrant natural solvent is a sweet orange oil: turps: eucalyptus oil=85%: 10%: 5%), just become the paint base-material to be dissolved in fragrant natural solvent.On the basis of this base-material, can produce varnish, enamel paint, aqueous latex paint.
Modified natural resin of the present invention can add or substitute following raw material in the compatibility: oleum lini, tung oil can use Viscotrol C, soya-bean oil, walnut oil, perilla oil, cannabis oil, oleum gossypii seminis, Oleum Cocois, Semen Maydis oil, Trisun Oil R 80, Rice pollard oil to replace; Dammar gum, rosin glyceride can use tetramethylolmethane glyceride, MALEIC ANHYDRIDE rosin fat to replace.
