Problems solved by technology

Generally speaking, before it is rolled, there are scales, grease, gray sand, and dirt on its surface (there are 35 kinds of terpenoids in the volatile matter of fir wood, and terpenoids refer to the existence in nature, and the molecular formula Hydrocarbons and their oxygen-containing derivatives that are multiples of isoprene units), if these dirt are not removed, the effectiveness of the coating cannot be fully exerted

Embodiment Construction

[0012] The technical solution of the present invention will be described in detail below.

[0013] Embodiments of the present invention disclose a kind of Chinese fir roller coating treatment method, comprising the following steps:

[0014] Step 1: Use a tool to clean up the precipitated turpentine, then wipe the wood surface with 20% acetone aqueous solution to dissolve the rosin, and then remove the solvent in time to avoid residual solvent, otherwise grease marks will be left after the solvent volatilizes. Affects coloring and film properties.

[0015] Step 2: Wipe the fir surface with 5.5% to 6% sodium carbonate hot water solution at 55 degrees Celsius to saponify the pine resin, and then wash the saponified matter with hot water.

[0016] Step 3: Wipe the wood surface with hot water at 70 degrees Celsius to remove residues and dry the wood surface. According to the principle of thermal expansion and contraction, wood is easy to warp and deform. If you paint on wet wood...

Abstract

The invention discloses a fir wood roll coating treatment method. The method comprises the steps that (1) pine gum which is separated out is cleared up by using a tool, and the wood surface is cleaned with an acetone aqueous solution of 20% to make the pine gum be dissolved; (2) the wood surface is cleaned with a sodium carbonate aqueous solution of 5.5-6% at 55 DEG C to saponify the pine gum, and then saponated substances are cleaned up with hot water; (3) the wood surface is cleaned with hot water of 70 DEG C to remove residues, and then is dried; (4) the wood surface is ground with abrasive paper, puttied fully twice, ground, dedusted and coated with a first pass of primer, and then the wood surface is dried with a mercury lamp dryer, polished and cleaned; and (5) the wood surface is coated with a first pass of finish paint and a second pass of finish paint through a roll coating machine, is dried through a curing machine, is dried for the second time through the mercury lamp dryer and finally is ground, smoothened, polished and cleaned to form a finished product. By means of the method, the fir wood can achieve a good decoration effect.

Description

technical field [0001] The invention relates to the technical field of furniture manufacturing, in particular to a method for treating Chinese fir by roller coating. Background technique [0002] Chinese fir boards are widely used in the selection of home decoration materials, and the environmental indicators can reach the E0 standard so far. Generally speaking, before it is rolled, there are scales, grease, gray sand, and dirt on its surface (there are 35 kinds of terpenoids in the volatile matter of fir wood, and terpenoids refer to the existence in nature, and the molecular formula Hydrocarbons and their oxygen-containing derivatives that are multiples of isoprene units), if these dirt are not removed, the effectiveness of the coating cannot be fully exerted. Therefore, appropriate pre-painting treatment processes must be carried out to meet different needs. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art and...
