Problems solved by technology

[0002] At the present stage, other manufacturers adopt the single-layer baking varnish process when making props, which has the advantages of low cost, short construction period, and easy construction, but the disadvantage is also very obvious. After 3-6 months of use, many bulges will appear on the surface of the props.
The so-called bulging is because the props (counters, display racks, showcases) are connected by air nails during processing, and then painted, but the props are placed in the mall due to temperature and humidity changes, and the plates will become damp due to the absorption of heavy moisture in the air. Air nails will push out, causing bulges and cracks on the surface of the props

Embodiment Construction

[0016] The present invention will be described in detail below in combination with specific embodiments.

[0017] The props referred to in the present invention are display racks or showcases for placing goods or ornaments; the reinforcing glue is special glue for carpentry, preferably wood master green environmental protection universal glue; putty is commonly known as putty, also known as polyester resin putty.

[0018] Technology of the present invention carries out according to the following steps:

[0019] Step 1: If figure 1 Shown is the prop box made by the method of the present invention, the prop box is coated with glue; the surface layer of the prop is constructed according to the design drawings, most of which are flat, and the surface of individual props is arc-shaped or streamlined. When a prop is not made When it is completed, it is called the prop box. When the prop box is finished, the surface is covered with reinforced glue (1mm wood master green environmenta...

Abstract

The invention discloses a composite top layer varnish stoving technology. The technology comprises the steps that a prop box body is coated with glue to an extent that the surface of the prop box body is fully coated with the fortified glue; when the fortified glue slightly shrinks and is dried, a composite top layer can be pasted; after the pasting is finished, dispersive type hammering is conducted two to three times by a rubber hammer from the central portion to the periphery; 1 mm to 2 mm expansion joints are reserved in the joint positions between plates during plane jointing, 45-degree chamfer angles are formed in all the plates when internal and external corner plates are jointed, it is guaranteed that the plate joints are formed in opposite angle edges and 1 mm to 2 mm expansion joints are reserved, all the composite top layer joint positions are coated with unsaturated polyester putty and rough grinding is conducted by abrasive paper; the whole body is coated with the unsaturated polyester putty, rough grinding is conducted one time by the abrasive paper, and accurate grinding is conducted two to three times by fine abrasive paper; the prop box body enters a painting workshop, undercoat spraying is conducted one to two times, and fine abrasive paper smoothing is conducted one time when the prop box body is dried in the air; topcoat spaying is conducted three to five times, the prop box body is placed in a varnish airing room after staying in a varnish stoving room for two hours until a completely dry effect is achieved, and then the whole manufacturing process is finished. The composite top layer varnish stoving technology has the advantages that plate surfaces are flatter, varnish surfaces are smoother, and the heave phenomenon is not likely to happen.

Description

technical field [0001] The invention belongs to the technical field of baking varnish, and relates to a composite surface layer baking varnish process. Background technique [0002] At the present stage, other manufacturers adopt the single-layer baking varnish process when making props, which has the advantages of low cost, short construction period, and easy construction, but the disadvantage is also very obvious. After 3-6 months of use, many bulges will appear on the surface of the props. . The so-called bulging is because the props (counters, display racks, showcases) are connected by air nails during processing, and then painted, but the props are placed in the mall due to temperature and humidity changes, and the plates will become damp due to the absorption of heavy moisture in the air. The air nails will push out, causing the surface of the props to bulge and crack. Contents of the invention [0003] The object of the present invention is to provide a composite ...
