Description
Technical field
The invention belongs to chemical field, and in particular to a kind of net taste alkyd resin and preparation method thereof.
Background technology
At present, smell is big after conventional alkyd resin based coatings have house ornamentation spraying application, and smell residence time length lacks
Point, the air ambient of interior is seriously affected, is unfavorable for the lifting of quality of life, it is suppressed that consumption increases, and particularly constrains
The further development of oil paint.
With Chinese national economy sustained and rapid development, environmental protection is increasingly paid attention to, and to net taste alkyd resin and adopts
Increasingly increased with the use demand of its obtained alkyd resin based coatings.In order to better meet related needs, this area at present
Some researchs are carried out with regard to reducing paint film odor, the smell for finding to remain after spraying is mainly derived from film forming procedure and can not joined
The small-molecule mixture that can not be vapored away in time again with curing reaction, thus the key for reducing paint film odor be to reduce these it is small
The ratio of molecular substance.In the prior art by replacing it method using vegetable oil without using aliphatic acid, to subtract
The ratio of few free fatty, is finally reached the effect that smell is relatively low after constructing.However, the plant due to more amount to be used
Oil, high temperature alcoholysis is just had to pass through on operating procedure the step for, otherwise because the compatibility of vegetable oil and resin is poor, very
Easily there is the phenomenon of turbid appearance and to ultimately result in paint film property poor.And the consequence that alcoholysis is brought is exactly under production efficiency
Drop, while the color of resin is also deep.In addition, by actual contrast, can not be shut out completely instead of aliphatic acid with vegetable oil
The smell of exhausted film.Therefore, in terms of film smell is reduced, existing alkyd resin based coatings still suffer from defect in performance,
Such as net taste is not sufficiently effective, while there is the problem of coating dryness is partially slow, particularly after temperature is down to zero, generally arrive
The degree that can not almost solidify, has had a strong impact on the production efficiency of application unit.This defect constrains pushing away for this kind of product

Table 2：The performance comparison of alkyd resin of the present invention and the alkyd resin prepared by comparative example
Smell classification in table 2：1 is tasteless, 2 substantially tasteless, 3 smells are faint, 4 smells are obvious, 5 smells are strong.
As seen from Table 2, the dimethylbenzene for changing concentration ＞ 60% into when the xylene solution that concentration is 99.5% in comparative example 1 is molten
During liquid, the smell dissipation of resulting alkyd resin is slower, and paint film just reaches the degree of substantially tasteless after spraying 24h；Work as contrast
The ratio of oleic acid is improved to after 22.1% in example 2, paint film odor clearly, even after 24h is sprayed paint film still also
There is faint smell；After the ratio of benzoic acid is improved to 6.4% in comparative example 3, smell is obvious and the residence time is grown, spray
Paint film still also has faint odor after applying 24h.In comparative example 4 without using vegetable oil after, in addition to dryness is slightly decreased, smell
And other performances have no significant change.The ratio of vegetable oil is improved to after 13.4 parts in comparative example 5, due to vegetable oil and resin
Compatibility is poor, causes resin turbid appearance, the performance of paint film each side is poor, and smell also receives large effect.
Alkyd resin of the present invention has been obviously improved the dryness especially low temperature dryness of resin, applying in high temperature environments
Work pot-life is longer (gel time), and paint film combination property is good, sprays substantially tasteless after 24h, to prepare net taste coating, paint
Filmogen is provided Deng product.
