Abstract
The invention discloses soybean oil modified unsaturated polyester impregnating varnish and a preparation method thereof. The soybean oil modified unsaturated polyester impregnating varnish is made from raw materials in parts by weight as follows: 200-250 parts of soybean oil, 40-50 parts of pentaerythritol, 0.1-0.2 parts of lithium hydroxide, 20-30 parts of neopentyl glycol, 50-65 parts of diethylene glycol, 70-85 parts of isophthalic acid, 68-75 parts of maleic anhydride, 0.7-1 part of hydroquinone, 500-600 parts of styrene, 17-20 parts of dicumyl peroxide and 1-1.5 parts of cobalt naphthenate. According to the invention, the soybean oil which has not only widest sources in our lives but also cheap price is utilized to modify unsaturated polyester, the soybean oil is added into polyester, the drying speed of varnish can be improved because the soybean oil is half-dry, and the varnish is improved in toughness and reduced in shrinkage ratio because the soybean oil has very long aliphatic chains.
Description
Technical field
The invention belongs to insullac technical field, relate to a kind of soybean oil modified unsaturated polyester impregnating varnish and preparation method thereof.
Background technology
Unsaturated polyester impregnating varnish is used for dip treating motor, electric apparatus coil, fill the gap in insulation system and micropore, and form continuous paint film on impregnated thing surface, and make coil be bonded to a solid entirety, effectively improve the globality of insulation system, thermal conductivity, moisture resistivity, the performance of dielectric strength and physical strength; But there is the shortcomings such as surface drying is comparatively slow, paint film is crisp firmly, shrinking percentage is large in the unsaturated polyester impregnating varnish of routine, has a strong impact on result of use.
Summary of the invention
For the problems referred to above, the technical problem to be solved in the present invention is to provide soybean oil modified unsaturated polyester impregnating varnish that a kind of drying varniss is fast, paint film toughness is high, paint film shrinking percentage is low and preparation method thereof.
Soybean oil modified unsaturated polyester impregnating varnish of the present invention, be made up of the raw material of following weight part:
Soybean oil 200-250, tetramethylolmethane 40-50, lithium hydroxide 0.1-0.2, neopentyl glycol 20-30, glycol ether 50-65, m-phthalic acid 70-85, MALEIC ANHYDRIDE 68-75, Resorcinol 0.7-1, vinylbenzene 500-600, dicumyl peroxide 17-20, cobalt naphthenate 1-1.5.
Preparation method of the present invention comprises the following steps:
(1) soybean oil, lithium hydroxide, tetramethylolmethane are dropped in reactor and carry out heating, stirring, reactor is warmed up to 240 DEG C, is incubated 2 hours;
(2) drop into m-phthalic acid, neopentyl glycol, glycol ether in a kettle. again, reactor continues to be warmed up to 198-202 DEG C, and it is qualified that reactor is incubated mixture acid number;
(3) drop into MALEIC ANHYDRIDE, Resorcinol in a kettle. again, reactor is warmed up to 198-202 DEG C again, and reactor is incubated mixture viscosity, acid number is qualified;
(4) mixture in reactor is put into dilution still, mixture in still to be diluted is cooled to after below 100 DEG C, vinylbenzene is dropped in dilution still, mixture in still to be diluted continues to be cooled to after below 50 DEG C, in dilution still, drop into dicumyl peroxide, cobalt naphthenate stirring.
Beneficial effect of the present invention: the present invention's wide, the most cheap soybean oil of originating in utilizing us to live carrys out modified unsaturated polyester, add soybean oil in the polyester, because soybean oil belongs to semi-drying, so the rate of drying of paint film can be improved, again because soybean oil has very long aliphatic chain, add toughness to paint film, decrease shrinking percentage.
