Embodiment 1

[0029] Raw material preparation: raw lacquer: 92%, bovine serum albumin: 5%, pyridine: 3%.

[0030] In the enzyme reactor, the raw lacquer (Ankang, Hanzhong, Chengkou, Maoba, Qinling and other areas) that have been filtered will have a frying pan fraction of more than 65% and a urushiol content of more than 50%. ), at normal temperature, feed oxygen, add 5% bovine serum albumin, 3% pyridine, heat preservation reaction for 8 hours, stirring speed is controlled at 50 / min~60 / min, then dehydration in temperature rise, moisture content is controlled at 5% , Observed with the naked eye, the raw lacquer turns from brown yellow to soy sauce color, and the finished product is obtained.

Embodiment 2

[0032] Raw material preparation: lacquer: 62%, sericin: 5%, ammonium acetate: 3%. Perilla oil: 20%, turpentine: 10%.

[0033] In the enzyme reactor, the raw lacquer (Ankang, Hanzhong, Chengkou, Maoba, Qinling and other areas) that have been filtered will have a frying pan fraction of more than 65% and a urushiol content of more than 50%. ), at normal temperature, feed oxygen, add 5% sericin, 3% ammonium acetate, control the temperature at 25°C, control the stirring speed at 50 / min~60 / min, keep the reaction for 4 hours, and then heat up for 40 ℃ dehydration, the water content is controlled at about 5%, keep the temperature and stirring speed constant, then add 20% perilla oil, react for 4 hours, then add turpentine, dilute to get the finished product.

Embodiment 3

[0035] The difference between this example and Example 2 is that the sericin in the raw material is replaced by a water-soluble polypeptide, and the rest are the same as Example 2.

Abstract

The invention discloses a raw lacquer refining method. By weight percent, the refined raw lacquer consists of the following materials: 60 percent to 95 percent of raw lacquer, 1 percent to 5 percent of active protein, 1 percent to 5 percent of pH regulator, 0 percent to 5 percent of biomass and 0 percent to 20 percent of diluent, and the percentages of the materials are added up to 100 percent. The method adopts the biochemical catalytic reaction principle for the first time, and is integrated with the biochemical reaction and control technique to refine the raw lacquer; the surface chemistry technique and the bio-enzyme catalysis microenvironment regulation technique are adopted for the first time; other renewable biomass is used; the surface activity function of the bioprotein is utilized for the first time to regulate the rheological behaviour of the raw lacquer; and the lacquer film has high transparency, adhesive force and rigidity, and can be toned. The product has the excellent acid resistance, corrosion resistance, water resistance, oil resistance and wear resistance of the raw lacquer, and can be directly coated on furniture or indoor decorations. The product is applicable to modern furniture and indoor decoration as well as the surface coating of instruments and equipment.

Description

technical field [0001] The invention relates to the preparation of raw lacquer, in particular to a method for refining raw lacquer. The refined raw lacquer prepared by the method is mainly used for modern furniture and interior decoration, and is also suitable for surface finishing of instruments and equipment. It has good performance and optical properties, heat resistance, water resistance, chemical resistance, wear resistance, high hardness, strong adhesion and high gloss. Background technique [0002] Raw lacquer has been used for the decoration of utensils and furniture items for 8,000 years, and now it is mainly used for the finishing of lacquerware crafts and mahogany furniture. Raw lacquer paint film has excellent performance, but the construction conditions and construction technology requirements are relatively high, it needs a specific temperature and humidity environment, and it has allergic reactions to the human body, thus limiting the scope of application.
