Abstract

The invention discloses a special water-based conductive seal primer for MDF. The primer is prepared from the following raw materials in parts by weight: 40 to 65 parts of self-crosslinking type epoxy modified polyurethane resin, 3 to 10 parts of electrolytic copper powder, 0.6 to 1.5 parts of a conductive agent, 0.03 to 0.5 part of a wetting agent, 0.1 to 0.7 part of a defoaming agent, 10.9 to 19.7 parts of a functional agent, 0.4 to 0.9 part of other performance additives, and 10.57 to 15 parts of water. The special water-based conductive seal primer for MDF enables MDF to have excellent electric conductivity by directly spray coating on the MDF, so that the production process is simplified; besides, the special water-based conductive seal primer for MDF has good sealing ability and adhesion, so that the volatilization of free formaldehyde and other harmful substances in the MDF is reduced, and the comprehensive performance is excellent.

Description

The special-purpose aqueous conduction seal coat of MDF
Technical field
The present invention relates to paint field, particularly relate to the special-purpose aqueous conduction seal coat of a kind of MDF.
Background technology
MDF and medium density fibre board (MDF), be by timber or vegetable fibre through mechanical separation and chemical treatment means, mix tackiness agent and water-resisting agent etc., then through a kind of artificial board that high temperature, high-pressure molding are made, be make the ideal artificial board of furniture.
Powder paint can provide has good scratch resistance and pollution resistance, can provide the selection of shades of colour and different surfaces effect simultaneously, and environmental protection, cost is low.
In traditional coating process, after electrically processing the surface of MDF, then carry out powder paint, the performance advantage of the sheet material of acquisition is equally matched with the powder paint of metallic surface, and significantly can reduce the cost of manufacture of conductive sheet metal, there is actual application value.But, before powder paint, first carry out the electrical process on MDF surface, be namely coated with and add conductive liquid, too increase the operation of production like this, and then to a certain degree add cost, reduce the price advantage of MDF powder coating.In addition, in the manufacturing processed of MDF, need to use tackiness agent all essentially, therefore the MDF after being shaped can discharge free formaldehyde, if seal coat effectively can not fill the trickle space on closed MDF surface, the formaldehyde that the less volatility of molecule is stronger easily penetrates paint film and is discharged in air, thus affects HUMAN HEALTH and cause environmental pollution.
Summary of the invention
Based on this, the object of the invention is to the defect overcoming prior art, the special-purpose aqueous conduction seal coat of a kind of MDF is provided.
