Abstract
The invention provides an odorless alkyd resin which comprises the following raw materials in parts by weight: 27-32 parts of dibasic acid or acid anhydride, 19-33 parts of alcohol, 11-22 parts of fatty acid, 1-5 parts of benzoic acid, 0.5-3 parts of vegetable oil, 25-50 parts of solvent and 0.03-0.2 part of antioxidant. The alcohol is dibasic alcohol and/or polylol. The alkyd resin provided by the invention has obviously higher dryness, and maintains the advantages of low odor and quick odor dissipation in the coating, paint and other products made from the alkyd resin. The odorless alkyd resin still has longer activation period in a high-temperature construction environment. The combination of the odorless alkyd resin and the matte paint has the advantages of favorable matting property and favorable comprehensive properties of the paint film. In practical application, the odorless alkyd resin can be well cured even at the low temperature of 0 DEG C, is basically odorless 12 hours after being sprayed and almost odorless after 24 hours, and thus, achieves the level of approximate to the water-based odorless paint.
Description
Technical field
The invention belongs to chemical field is and in particular to a kind of net taste alkyd resin and preparation method thereof.
Background technology
At present, after conventional alkyd resin based coatings have house ornamentation spraying application, abnormal smells from the patient is big, the lacking of abnormal smells from the patient residence time length
Point, badly influences the air ambient of interior, is unfavorable for the lifting of quality of life it is suppressed that consumption increases, particularly constrains
The development further of oil paint.
With Chinese national economy sustained and rapid development, environmental conservation is increasingly paid attention to, to net taste alkyd resin and adopt
The use demand of the alkyd resin based coatings being obtained with it increasingly increases.In order to better meet related needs, current this area
Some researchs are carried out with regard to reducing paint film odor, after finding spraying, the abnormal smells from the patient of residual is mainly derived from film forming procedure and can not join
The small-molecule mixture that again can not vapor away in time with curing reaction, therefore reducing the minimizing that it is critical only that of paint film odor, these are little
The ratio of molecular substance.In prior art by do not replaced using vegetable oil using fatty acid method, to subtract
The ratio of few free fatty, is finally reached the relatively low effect of abnormal smells from the patient after construction.However, the plant due to more amount to be used
Oil, is necessary for the step for high temperature alcoholysis, otherwise because vegetable oil is poor with the compatibility of resin, very on operating procedure
The phenomenon of turbid appearance easily occurs and to ultimately result in paint film property poor.And the consequence that alcoholysis brings is exactly under production efficiency
Fall, the color of resin is also deep simultaneously.In addition, through actual contrast, replacing fatty acid not shut out completely with vegetable oil
The abnormal smells from the patient of exhausted film.Therefore, in terms of reducing film abnormal smells from the patient, existing alkyd resin based coatings still suffer from defect in performance,
For example net taste is not sufficiently effective, occurs in that the partially slow problem of coating dryness simultaneously, particularly after temperature is down to zero, generally arrives
The degree that almost cannot solidify, has had a strong impact on the production efficiency of application unit.This defect constrains pushing away of this kind of product
Wide and application, particularly in the temperature such as North China lower ground area.

Table 2: the performance comparison of alkyd resin of the present invention and the alkyd resin prepared by comparative example
Abnormal smells from the patient classification in table 2: 1 is tasteless, 2 substantially tasteless, 3 abnormal smells from the patients are faint, 4 abnormal smells from the patients are obvious, 5 abnormal smells from the patients are strong.
As seen from Table 2, when in comparative example 1 concentration be 99.5% xylene solution change into concentration ＞ 60% dimethylbenzene molten
During liquid, the abnormal smells from the patient of obtained alkyd resin dissipates relatively slowly, and after spraying 24h, paint film just reaches the degree of substantially tasteless；Work as contrast
In example 2, the ratio of Oleic acid is improved to after 22.1%, paint film odor clearly, even paint film is still also after spraying 24h
There is faint abnormal smells from the patient；After benzoic ratio being improved to 6.4% in comparative example 3, substantially and the residence time is long for abnormal smells from the patient, spray
After applying 24h, paint film still also has faint odor.After not using vegetable oil in comparative example 4, in addition to dryness is slightly decreased, abnormal smells from the patient
And other performances have no significant change.In comparative example 5, the ratio of vegetable oil is improved to after 13.4 parts, due to vegetable oil and resin
The compatibility is poor, leads to resin turbid appearance, and the performance of paint film each side is all poor, and abnormal smells from the patient 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 longer (gel time), paint film combination property is good, and substantially tasteless after spraying 24h, for preparing net taste coating, paint
There is provided filmogen Deng product.
