preparation example Construction

[0033] The preparation method of above-mentioned varnish comprises the following steps:

[0034] Step S110, by mass percentage, mixing 9%-15% of the first bio-oil and 40%-50% of the second bio-oil and heating to 135°C-145°C to obtain mixed bio-oil.

[0035] Preferably, the first bio-oil and the second bio-oil are added into the reactor and heated with stirring.

[0036] Step S120, under stirring, add 40%-50% petroleum resin to the mixed bio-oil in stages until the petroleum resin is completely dissolved, heat up to 155°C-165°C and keep it warm for 1-1.5 hours before use No more than 5% of the first bio-oil adjusts the varnish with a viscosity of 5000mpa.s-12000mpa.s (25°C).

[0037] Preferably, the petroleum resin is added into the mixed bio-oil three times.

[0038] Step S130, filtering the obtained varnish at 80° C. to 100° C. to make the fineness of the varnish ≤ 15 microns.

[0039] Further, bag filters are used for filtration.

[0040] Preferably, the obtained varnish...

Abstract

The invention relates to a varnish and a preparation method thereof. The varnish comprises, by mass, 9-20% of first bio-oil, 40-50% of second bio-oil and 40-50% of petroleum resin; the first bio-oil is fatty acid methyl ester; and the second bio-oil is a product obtained through the following steps: reacting illegal cooking oil with methanol, removing glycerin, dehydrating, and removing diesel oil. The varnish has the advantages of low cost and environmental protection.

Description

technical field [0001] The invention relates to a varnish and a preparation method thereof. Background technique [0002] With the development of the world and the needs of people's lives, the printing industry has developed rapidly in recent years, and the amount of ink used is increasing. Mineral oil is used as varnish in the existing ink, and the volatilization of harmful components in the mineral oil will have a poisonous effect on the atmosphere and the human body, and the use of environmentally friendly inks has become an inevitable trend. [0003] At present, soybean ink formulated with soybean oil is widely used as an environmentally friendly ink. However, the price of soybean oil is high, which leads to high ink cost. Contents of the invention [0004] Based on this, it is necessary to provide a relatively environmentally friendly and low-cost varnish and a preparation method thereof. [0005] A kind of varnish, according to mass percentage, comprises the follow...
