Abstract

The invention discloses a PVC furniture film / PVF plastic film water-based adhesive. The PVC furniture film / PVF plastic film water-based adhesive is formed by the following raw materials according to aweight ratio: 23-75 parts of a bonding resin, 0.6-0.8 parts of a wetting agent, 1-12 parts of a thickening agent, 0.1-0.42 parts of an antifoaming agent, 0.02-0.2 parts of a preservative, 10-29 partsof low mass molecule alcohol, and 13.6-38.68 parts of deionized water. The adhesive has the higher peel strength to a PVC furniture film and a PVF plastic film, and through the rational combination of each auxiliary, the sizing operation simplification of a product to PVF plastic is guaranteed. A common intaglio printing technology is used, so the PVF film can be coated by the adhesive. Comparedwith a traditional PVC furniture film laminated by using a PVC wearing layer, the PVC furniture film bonded with the PVF layer by using the adhesive is capable of greatly improving the ultraviolet radiation resistance, and the product is beneficial to promote in the outdoor places.

Description

[0001] (1) Technical field [0002] The invention relates to a water-based adhesive and a preparation method thereof, in particular to a water-based adhesive capable of bonding printed PVC (polyvinyl chloride) furniture films and PVF (polyvinyl fluoride) plastic films and a preparation method thereof. The above-mentioned adhesive can be applied to hot-press lamination of PVC furniture film and PVF plastic film. [0003] (2) Background technology [0004] After the PVC furniture film is printed, it needs to be bonded with the PVC wear-resistant layer for a short time at high temperature (160-170°C, 6-15s, no specific pressure requirements). The wear-resistant layer mainly plays an anti-scratch, anti-scratch, Protection against water and oil stains. The furniture film laminated with PVC wear-resistant layer is generally used in indoor furniture panels, door panels, etc. However, due to the limited weather resistance of the PVC wear-resistant layer itself, it is difficult to app...
