Abstract

The invention discloses a high-pressure fiber decorative sheet and a manufacturing method for continuous production thereof. The manufacturing method includes that fiber paper of a decorative layer and fiber paper of a core layer are fed into a high-temperature air chamber from fiber paper or non-woven fabric of a bottom layer, ground paper is pulled by a take-up unit and then subjected to continuous hot pressing by a steel belt in the high-temperature air chamber to form a sheet blank, and the sheet blank is wound after being trimmed. The decorative layer refers to the fiber paper which is primarily dipped with one of acrylic resin and toughened modified melamine formaldehyde resin and secondarily coated with toughened modified melamine formaldehyde resin; the core layer refers to the fiber paper which is dipped with toughened modified phenolic resin, and the bottom layer refers to one of fiber non-woven fabric and fiber paper. By the manufacturing method, the yield is increased by twice, energy consumption in process is one half, the number of staff is one fifth of that needed in the prior art, processes are simple and convenient, floor area is small, and semi-finished and finished products are soft and can be rolled; the decorative sheet can be used as a coating material for jambs with r angle smaller than 3mm or as a decorative laminated board.

Description

technical field [0001] The invention relates to the field of decorative boards, in particular to a preparation method for continuous production of high-pressure fiber decorative boards and high-pressure fiber decorative boards. Background technique [0002] Fiber decorative board, also known as wood-based panel, is a thermosetting resin product made of a variety of special fiber materials chemically treated with high-temperature and high-pressure adhesives. The surface of the product has various texture patterns, soft color, and high durability. Good physical properties such as abrasion resistance, heat resistance, cold resistance and flame retardancy. It is used in high-end cabinets, walls, floors, etc. as a decorative surface. [0003] The thermosetting resin used in traditional multi-layer hot-pressed decorative laminates not only has a short storage period, but also the impregnated film paper is hard and brittle. The multi-layer press consumes a lot of energy, high labo...
