Abstract

The invention discloses PVC (polyvinyl chloride) edge seal adhesive, made from, by weight, 38-48% of deionized water, 0.8-2% of an anionic emulsifier, 0.1-0.2% of a reactive emulsifier, 0.1-0.2% of abuffer agent, 2.5-4.5% of a stabilizer, 1.5-3.5% of a crosslinking agent, 0.2-0.5% of an initiator, 20-28% of an acrylic monomer, 20-30% of vinyl acetate, 0.5-1% of an internal plasticization monomer,3-10% of modified tackifying resin emulsion, 0.05-0.1% of a wetting agent, and 0.1-0.3% of a film-forming aid. In addition, the invention also discloses a preparation method of the PVC edge seal adhesive. The PVC edge seal adhesive is convenient to use, can cure at normal temperature, has high adhesive strength and good aging resistance, is free of organic solvents and formaldehydes and is nontoxic and environmentally friendly.

Description

technical field [0001] The present invention relates to a kind of pigment, especially relates to the pigment with natural fluidity used in fine arts, moreover, the present invention also relates to the preparation method of this pigment. Background technique [0002] With the rapid improvement of people's living standards, the demand for panels in building decoration and furniture manufacturing is increasing. Traditional solid wood boards can no longer meet the needs of social and economic development due to factors such as limited forest resources and limitations in the use of boards. As a representative of new boards, man-made boards are characterized by low production costs, high utilization of wood, and excellent board strength. It has been widely used in furniture manufacturing and architectural decoration. The internal material structure of wood-based panels is quite different from that of solid wood. Generally, after cutting, the surface is rough and uneven, and is e...
