Embodiment 1

[0028] The present embodiment provides a kind of preparation method of colored raw lacquer, and this method specifically comprises the following steps:

[0029] Step 1: After filtering the raw lacquer to remove impurities, add it to the reaction kettle, gradually raise the temperature to 35°C, add white rot fungus laccase (mass ratio: raw lacquer:white rot fungus laccase=100:5) into the reaction kettle, slowly Introduce oxygen and stir for 7 hours to obtain refined lacquer microemulsion;

[0030] Step two, add hypophosphorous acid (mass ratio is, raw lacquer: hypophosphorous acid=100:1) in the refined microemulsion of raw lacquer gained in step one, continue to stir at 40 ℃, until solid content reaches 95%, add tung oil (mass ratio For, raw lacquer: tung oil=100:10), can get transparent raw lacquer;

[0031] Step 3, adding vermilion powder to cooked tung oil (mass ratio: vermilion powder: cooked tung oil=1:1), high-speed dispersion and grinding for 2 hours, red micron-scale c...

Embodiment 2

[0036] The present embodiment provides a kind of preparation method of colored raw lacquer, and this method specifically comprises the following steps:

[0037] Step 1: After filtering the raw lacquer to remove impurities, add it to the reaction kettle, gradually raise the temperature to 50°C, add white rot fungus laccase (mass ratio: raw lacquer:white rot fungus laccase=100:5) into the reaction kettle, slowly Introduce oxygen and stir for 7.5 hours to obtain refined lacquer microemulsion;

[0038] Step 2, add phosphite (mass ratio is, raw lacquer: phosphite=100:1) to the refined microemulsion of raw lacquer obtained in step 1, continue stirring at 50°C until the solid content reaches 92%, add tung oil ( Mass ratio is, raw lacquer: tung oil=100:10), can get transparent raw lacquer;

[0039] Step 3, adding Fast Yellow to polymerized linseed oil (mass ratio: Fast Yellow: Polymerized Linseed Oil = 1:1), high-speed dispersion and grinding for 1 hour, yellow micron-scale color pas...

Embodiment 3

[0044] The present embodiment provides a kind of preparation method of colored raw lacquer, and this method specifically comprises the following steps:

[0045] Step 1: After filtering the raw lacquer to remove impurities, add it to the reaction kettle, gradually heat up to 30° C., add Aspergillus oryzae laccase (mass ratio is, raw lacquer: Aspergillus oryzae laccase=100:5) into the reaction kettle, slowly Introduce oxygen and stir for 10 hours to obtain refined lacquer microemulsion;

[0046] Step two, add hypophosphorous acid (mass ratio is, raw lacquer: hypophosphorous acid=100:1) to the refined microemulsion of raw lacquer obtained in step one, continue stirring at 30°C until the solid content reaches 97%, add linseed oil (mass Raw lacquer: linseed oil=100:10), linseed oil can also be replaced by catalpa oil to get transparent lacquer;

[0047] Step 3, adding phthalocyanine blue to cooked tung oil (mass ratio: phthalocyanine blue: cooked tung oil = 1:1), high-speed disper...

Abstract

The present invention provides a preparation method of a colored raw lacquer. The method is as below: adding fungal laccase into a raw lacquer, introducing oxygen, stirring for 7h-10h to obtain refined lacquer microemulsion; and mixing the refined lacquer microemulsion with a micron paste to obtain colored raw lacquer. The refining process of raw lacquer is by introducing fungal laccase for refining in oxygen atmosphere, greatly reduces the refining time, and only needs 7-10 h. Based on the biological reaction characteristics of raw lacquer, the invention uses the principle of enzyme engineering technology for refining processing of raw lacquer, and improves the production efficiency of lacquer production technology. The introduction of a functional group of a color subtractive group in the vitrification stage of raw lacquer well enhances the transparency and dyeing property of the raw lacquer. In the stage of colored raw lacquer, a micron pigment paste prepared from pigment and dry vegetable oil is used, so that the color raw lacquer can be more easily dispersed and blended in the modulation process. The colored lacquer prepared by the invention has full and bright color, maintains the original characteristics of the raw lacquer, and also has good workability.

Description

technical field [0001] The invention belongs to the field of raw lacquer, relates to colored raw lacquer, in particular to a preparation method of colored raw lacquer. Background technique [0002] The lacquer tree is a unique ecological economy, fast-growing and soil and water conservation tree species in my country. The lacquer harvested from the phloem of the lacquer tree is a precious ecological material with unique super durability, high decorativeness and heavy corrosion resistance. The lacquer decorated with lacquer Utensils have always been loved by people, and they have not faded for thousands of years. However, the traditional refining process of raw lacquer is simple refining process such as sun exposure, heating dehydration, blending, etc. This lacquer making technology has been continued to this day, with primitive technical means and low production efficiency. However, the special composition and structure of raw lacquer make it "black" after drying, and it is ...
