Embodiment

[0020] Taking the production of 1000kg of the amino alkyd dipping varnish of the present invention as an example below, the parts by weight of the raw materials for its preparation are: 17 parts of waste cooking oil (170 kg of waste oil), 2 parts of dry vegetable oil (20 kg of tung oil), polyol (60 kg of pentaerythritol+diglycol Alcohol 35kg) 9.5 parts, catalyst (lithium hydroxide 0.11kg) 0.011 parts, dibasic acid or acid anhydride (phthalic anhydride 130 kg) 13 parts, monobasic acid (rosin 65 kg) 6.5 parts, amino resin (solid content of 60wt% butylated melamine formaldehyde resin (100kg) 6 parts and dilute solvent (xylene 240kg + toluene 220kg) 46 parts.

[0021] The concrete steps of preparing amino alkyd dipping paint are:

[0022] ⑴Put 170kg of crude waste oil into the reaction kettle, start stirring, add 5kg of tap water and 0.17kg of phosphoric acid, rise to 65°C and stir for 0.5 hours, stop stirring, let stand for 1 hour, and let go of the water phase in the lower layer...

Abstract

The invention discloses an alkyd-amine impregnating varnish prepared from discarded edible oil. The alkyd-amine impregnating varnish is prepared from the following raw materials in parts by weight of 10-20 parts of discarded edible oil, 1-5 parts of dry vegetable oil, 7-13 parts of polyhydric alcohols, 0.01-0.02 part of catalyst, 10-16 parts of binary acid or anhydride, 3-8 parts of monobasic acid, 3-8 parts of amino resin and 45-55 parts of diluent. Compare with the prior art, the alkyd-amine impregnating varnish disclosed by the invention has the advantages that the discarded edible oil with low price is adopted to replace the vegetable oil or vegetable oil acids used in the traditional formula to prepare the alkyd-amine impregnating varnish, the cost of per ton of the alkyd-amine impregnating varnish can be reduced by about 700yuan, and the property of the alkyd-amine impregnating varnish is not lower than that of an existing product.

Description

technical field [0001] The invention relates to an amino alkyd dipping paint, in particular to a low-cost amino alkyd dipping paint prepared from waste cooking oil. Background technique [0002] Amino alkyd impregnating varnish is a drying-type amino alkyd resin solution with good electrical insulation performance, cohesiveness and thick layer curing ability. The paint base of amino alkyd dipping varnish is mainly composed of amino resin and alkyd resin, and the alkyd resin contains 20-50wt% fatty acid. The alkyd resin component of the traditional amino alkyd dipping paint mainly uses dry vegetable oils or vegetable oleic acids containing a large number of unsaturated bonds such as linseed oil, castor oil, soybean oil, catalpa oil, and tung oil to introduce fatty acids. These dry vegetable oils or fatty acids The price is higher, which increases the manufacturing cost of amino alkyd dipping paint. [0003] Since the amino alkyd impregnating varnish is baked and cured, the ...
