Problems solved by technology

In order to remove this white spot, the wood needs to be re-treated, which undoubtedly increases the production cost and production time
In addition, excess hydraulic oil can soften painted layers (such as nitrocellulose coatings), causing adhesion problems between the coating and wood materials

preparation example Construction

[0042] The preparation of the oily composition of the present invention can be carried out by using methods for preparing compositions well known to those skilled in the art. For example, the components in the oily composition can be mixed simultaneously using a container-replaceable mixer, a roller mixer, and any other paint mixing device known to those of ordinary skill in the art to be suitable for mixing the composition to form the oily composition, Or first mix the oligomer and non-reactive diluent uniformly, and then add unsaturated fatty oil to form an oily composition.

[0043] In a preferred embodiment of the present invention, the oily composition for wood processing, relative to the total weight of the oily composition, comprises:

[0044] a) 20-80% by weight of an unsaturated fatty oil with an iodine value of at least 100;

[0045] b) 20-80% by weight of oligomers modified with unsaturated fatty oils having an iodine value of at least 100;

[0066] Example 3: Applying a Nitrocellulose Coating

[0067] Step a. Engraving Wooden Substrate

[0068] Wooden furniture parts (wooden substrates) are engraved by hand or machine according to design, while using the oily composition according to the invention as coolant. The carved furniture parts are then sent to the assembly line for assembly or processing and polished smooth, and then ready for the painting process.

[0069] Step b. Apply Nitrocellulose Coating

[0070] The coating process is a conventional process in the art. The specific process is as follows: the stain is applied to the wood substrate, and then the nitrocellulose sealer (NC wash coat) is applied. After drying, the sealer primer is sanded and then varnished. Next apply two coats of nitrocellulose sealer with sanding in between. Finish by spraying stain on the sanded smooth sealer, followed by two coats of nitrocellulose varnish.

[0071] The inventors have found that the application of the ni...

Abstract

The invention relates to an oily composition for wood processing and application thereof. The oily composition for wood processing contains 20-80 wt% of unsaturated fatty oil with the iodine value being at least 100, 20-80 wt% of low polymer modified by the unsaturated fatty oil with the iodine value being at least 100, 0-30 wt% of unreactive diluent and 0-2 wt% of drying agent, relative to the total weight of the oily composition. The invention further relates to a method for manufacturing wooden furniture, comprising the following steps of: coating the oily composition provided by the invention on a wooden base material and carving the wooden base material by adopting the oily composition as a coolant.

Description

technical field [0001] The present invention relates to an oily composition, more specifically, to an oily composition for wood processing. The invention also relates to the use of this oily composition in woodworking. Background technique [0002] In the past wooden furniture manufacturing process, craftsmen manually cut (such as carving) wooden furniture to form wooden furniture with different sizes and different patterns. Early carvings were usually simple geometric shapes. As sculpting tools improved, carvings became more and more aesthetically pleasing, often featuring lines of simple elements commonly found in nature (such as flowers, leaves, vines, etc.). [0003] Wood carving can be done by hand carving or by machine carving. Hand-carving is the most delicate work in furniture processing. Through carving, the texture of wood is highlighted and the corners are naturally transitioned while showing patterns through carving. But hand-carving artisans can only carve o...
