Embodiment 1

[0060] By weight percentage, the composition of the wood sealer primer of the present embodiment is as follows:

[0061] Component A:

[0062] TDI adduct curing agent 25%

[0063] Aromatic solvents 35%

[0064] Ester solvent 40%

[0065] Component B:

[0066] Hydroxyl alkyd resin 70%,

[0067] Aromatic solvent 10%,

[0068] Ester solvent 10%,

[0069] Ketone solvents 10%.

[0070] Put the materials of component A and component B into the dispersing tank according to the above ratio, and disperse and stir at a medium speed (2000-3000 rpm) for 15-20 minutes. Stir well, filter and pack with 300 mesh. Part A and Part B are packaged separately.

[0071] Mix component A and component B at a ratio of 0.5:0.2 and apply it on the wood surface. The construction process is: spray once, at an interval of 30-60 minutes, then spray again, and at an interval of 30-60 minutes, spray again. After 3-6 hours after the wood sealing primer paint film dries, sand it and spray the unsatura...

Embodiment 2

[0073] By weight percentage, the composition of the wood sealer primer of the present embodiment is as follows:

[0074] Component A:

[0075] TDI adduct curing agent 75%

[0076] Aromatic solvent 5%,

[0077] Ester solvent 15%.

[0078] Component B:

[0079] Hydroxy-containing acrylic resin 70%,

[0080] Aromatic solvent 10%,

[0081] Ester solvent 10%,

[0082] Ketone solvents 10%.

[0083] Feed the materials of component A and component B according to the above order, disperse and stir evenly, filter and pack with 300 mesh. Part A and Part B are packaged separately.

[0084] Mix component A and component B at a ratio of 1:1 and apply it on the wood surface. The construction process is: spray once, at an interval of 30-60 minutes, then spray again, and at an interval of 30-60 minutes, spray again. After 3-6 hours after the wood sealing primer paint film dries, sand it and spray the unsaturated polyester paint without poor adhesion or paint falling off.

Abstract

The invention discloses a wood enclosing primer and an application thereof. The wood enclosing primer is taken as an enclosing primer for grease-containing wood, and consists of a component A and a component B, wherein the component A consists of a first organic solvent and an isocyanate curing agent; the component B consists of a second organic solvent and a alkyd resin, or consists of a second organic solvent and hydroxyl-containing acrylic resin; and the components A and B are packaged separately. During use, the component A and the component B are mixed in the ratio of (0.5-2):(0.2-1), and is applied to the surface of wood. The wood enclosing primer has the advantages of good wood grease enclosing effect, continuous operability, short construction time and easiness for constructing, grease of wood can be enclosed within 3-5 hours, and the situations of poor adhesion and paint removal occurring during spraying of unsaturated polyester paint on grease-containing wood.

Description

technical field [0001] The invention relates to the field of wood coatings, in particular to a wood sealing primer and its application. The wood sealing primer is mainly used as a sealing primer for wood with heavy oil content. Background technique [0002] Due to the high solid content, high fullness and high filling properties of unsaturated polyester coatings, unsaturated polyester coatings are often used for primer spraying of high-grade woodware. [0003] However, many of the woods used in high-end musical instruments and furniture factories are woods with heavy oil content, such as rosewood, catalpa wood, walnut and other woods. This type of wood contains many resinous secretions, that is, oil. These greases will cause the unsaturated polyester paint to not dry when the unsaturated polyester paint is sprayed on the wood, which will cause poor paint adhesion and peel off of the paint film. To solve the above phenomenon, only the oil is sealed in the wood, and the wood...
