CN104629509A - Japanning method of poplar plywood - Google Patents

Abstract

The invention provides a japanning method of poplar plywood. After japanning, paint and the poplar plywood are bonded preferably, and shedding is not easily caused. The japanning method comprises following steps: China wood oil, trimethylolpropane diallyl ether, maleic anhydride, propylene glycol, linseed fatty acid, triethylamine, and rosin are mixed fully in a mixer, an obtained mixture is allowed to stand for 30min, and then is reacted for 3h in a thermal insulation box at 200 DEG C; paraffin is added, the temperature of the thermal insulation box is increased to 255 DEG C, and an obtained mixed material is subjected to full reaction for 3h; benzoin isopropyl ether and 5% of a nonionic surfactant aqueous solution are added, an obtained product is mixed uniformly in the mixer, and is allowed to stand for 20min at 30 DEG C so as to obtain a paint; the paint is sprayed onto the poplar plywood, the processed poplar plywood is subjected to infrared lamp grilling for 25min, sweeping with hot air of 80 DEG C, and ultraviolet lamp grilling for 20min.

Description

A kind of lacquering technique of poplar plywood

technical field

The present invention relates to a kind of lacquering technique of poplar plywood.

background technology

Glued board is one of furniture common used material, is usually to be glued together by the orthogonal assembly of adjacent layers grain direction by one group of veneer to form, and its dash board and inner plating are configured in the both sides of central core or plate core symmetrically usually.Conventional has three-ply-wood, five-ply board etc.The wherein one of glued board is poplar plywood, and after japanning, the paint on glued board easily comes off, and causes the surface cleaning performance of furniture and humidity resistance to reduce.

summary of the invention

The technical problem to be solved in the present invention is to provide a kind of lacquering technique of poplar plywood, after japanning, paint and glued board associativity good, difficult drop-off.

In order to solve the problems of the technologies described above, technical scheme of the present invention is:

A lacquering technique for poplar plywood, step is as follows:

1) proportional reserve system is clicked for paint raw materials:

0.5Kg tung oil, 3.3-3.4Kg trishydroxymethyl propadiene propyl ether, 0.5Kg paraffin, 8.5-8.8Kg MALEIC ANHYDRIDE, 4.6-4.8Kg propylene glycol, 98-99Kg linseed fatty acid, 3.5-3.6Kg triethylamine, 0.3-0.35Kg rosin, 10-11Kg benzoin isopropyl ether and 160Kg5% nonionic surfactant water-soluble liquid;

2) preparation paint:

Tung oil, trishydroxymethyl propadiene propyl ether, MALEIC ANHYDRIDE, propylene glycol, linseed fatty acid, triethylamine and rosin are fully mixed in stirrer, static 30min, then being positioned over temperature is react 3h in the insulation can of 200 DEG C, add paraffin wherein, then insulation can temperature is adjusted to 255 DEG C and fully reacts 3h, finally add benzoin isopropyl ether and 5% nonionic surfactant water-soluble liquid, mixing in stirrer also places 20min at 30 DEG C, obtains paint;

3) by the paint spraying of above-mentioned acquisition on poplar plywood, then at infrared lamp according to scorching 25min, then use 80 DEG C of warm air blowoff, and then with ultraviolet lamp according to scorching 20 min.

By the fully mixing also fully reaction in stirrer of tung oil, trishydroxymethyl propadiene propyl ether, MALEIC ANHYDRIDE, propylene glycol, linseed fatty acid, triethylamine and rosin, then add paraffin and continue reaction, then add benzoin isopropyl ether and 5% nonionic surfactant water-soluble liquid, be deployed into paint.By glued board japanning, and infrared lamp photograph scorches, warm air blowoff, again ultraviolet lamp are shone and scorched.By this lacquering technique, paint and poplar plywood are combined closely, and combination stability is good.

Embodiment

A lacquering technique for poplar plywood, step is as follows:

1) proportional reserve system is clicked for paint raw materials:

0.5Kg tung oil, 3.3-3.4Kg trishydroxymethyl propadiene propyl ether, 0.5Kg paraffin, 8.5-8.8Kg MALEIC ANHYDRIDE, 4.6-4.8Kg propylene glycol, 98-99Kg linseed fatty acid, 3.5-3.6Kg triethylamine, 0.3-0.35Kg rosin, 10-11Kg benzoin isopropyl ether and 160Kg5% nonionic surfactant water-soluble liquid;

2) preparation paint:

Tung oil, trishydroxymethyl propadiene propyl ether, MALEIC ANHYDRIDE, propylene glycol, linseed fatty acid, triethylamine and rosin are fully mixed in stirrer, static 30min, then being positioned over temperature is react 3h in the insulation can of 200 DEG C, add paraffin wherein, then insulation can temperature is adjusted to 255 DEG C and fully reacts 3h, finally add benzoin isopropyl ether and 5% nonionic surfactant water-soluble liquid, mixing in stirrer also places 20min at 30 DEG C, obtains paint;

3) by the paint spraying of above-mentioned acquisition on poplar plywood, then at infrared lamp according to scorching 25min, then use 80 DEG C of warm air blowoff, and then with ultraviolet lamp according to scorching 20 min.
