Abstract

The production process of the high pressure decorating laminated board with thermosetting resin soaked paper includes the following steps: 1. painting anticorrosive resin onto stripping paper in the painted amount of 100-200 %; 2. combining the stripping paper, decorating paper soaked with melamine and several sheets of phenolic resin soaked kraft paper to form the board blank; 3. hot pressing the board blank in press at 120-150 deg.c and 5.0-10.0 MPa for 30-60 min; and 4. cutting. The high pressure decorating laminated board of the present invention has anticorrosive transparent coating formed with melamine to form unique anticorrosive performance, and beautiful and hard surface caused by the epoxy resin, and may be used as ideal decorating material.

Description

Technical field [0001] The invention relates to a method for preparing a decorative laminate board, in particular to a method for preparing a decorative laminate board with strong acid and alkali corrosion resistance. Background technique [0002] The physical and chemical type thermosetting resin impregnated paper high-pressure decorative laminate (corrosion-resistant physical and chemical board) is a kind of wear-resistant, heat-resistant, and impact-resistant performance in addition to the flat general-purpose high-pressure decorative board and the post-formed high-pressure decorative board. It has the unique performance of resistance to strong acid and strong alkali corrosion; it is an ideal material for the replacement of ceramic tiles, lacquer, rubber and other veneers for the experimental work surfaces of scientific research institutions, medical and health institutions. [0003] In order to achieve a high degree of corrosion resistance for the work surface of the laborato...
