Abstract
The invention discloses a method for preparing high-density wear-resistant immersion film-coated fabrics, and relates to preparation of immersion film-coated fabrics. Immersion glue solution is prepared by mixing phenolic resin or melamine resin, a sequestrant, a toner, a form release agent and water in proportion; and non-woven fabrics are made of plastics of polypropylene, polyethylene or polyvinyl chloride, or chemical fibers of terylene, chinlon, polyethylene fiber or polypropylene fiber, or plant fibers; and the method comprises working procedures of immersion and drying, wherein repeat twice warm drying is needed, and the temperature is between 60 and 150 DEG C. The immersion film-coated fabrics have even cluster, high density, smooth surface, wear resistance of 600 turns, no grinning effect, rich non-woven fabric resources and medium price, and are ideal film-coated fabrics for artificial boards and building templates; and the method can reduce a processing procedure of film coating of a base material.
Description
Technical field
The present invention relates to a kind of immersion film-coated fabrics, especially a kind of high-density wear-resistant immersion film-coated fabrics.
Background technology
The overlay film building template that the impregnated paper veneer base material is produced with strengthen decorative panel and not only will stand repeated disassembled and assembled, and to have characteristics such as wear-resisting, mar-proof, stretch-proof and surface smoothness height.But in the raw material of artifical plate preparation, special in the feedstock production of glued board and oriented structure chipboard, most of logs adopt the fast-growing woods kind; Like poplar, pine tree, birch, eucalyptus, fast-growing woods kind surface knot is many, and fiber is coarse; Cause most of plate faces to need after repairing and secondary operations, could carry out overlay film processing with traditional immersion tectorial paper; Owing to can't automation repair, the artificial plate face of repairing its moisture content except center fullness also is difficult to control, adds in the cave that substrate assembly workshop section substrate is hidden and causes the foaming of overlay film face, be full of cracks, stripping phenomenon easily; Cause the product defect rate high, quality is unstable.But, also do not have suitable overlay film to use impregnated paper in the prior art.
Summary of the invention
In order to be adapted to produce overlay film building template and the needs of strengthening decorative panel, the invention provides a kind of high-density wear-resistant immersion film-coated fabrics, this film-coated fabrics can be filled up the defective of substrate surface; Be easy to demoulding; Improved production efficiency, and had the surface smoothness height, ABRASION RESISTANCE is strong; Can use the serviceability that reduces cost repeatedly.
The present invention solves the concrete scheme that its technical problem adopts and comprises preparation nonwoven fabric dipping glue, the warm dried processing step of dipping:

Described nonwoven fabric contains 1-2 layer web layer or fabric, and woven fabric or knitted fabric content are 100～300g/m in the nonwoven fabric
2, final finished content is 120～500g/m
2
Described dipping temperature is done operation and is repeatedly twice, can increase the uniformity and the wearing layer thickness of film-coated fabrics like this, and the dried temperature of temperature is 60 ℃～150 ℃, and baking temperature thereafter is 130 ℃～150 ℃, after the cooling, cuts.
Required capital equipment is ctp response still, glue mixer, soak drying machine and general general horizontal or vertical impregnating equipment in technical process.
Through check, its abrasion resistance reaches 600 changes above no grinning effect, and the building template that is adapted to repeated disassembled and assembled uses.
As being exclusively used in base material building template wooden or bamboo matter and the surface coating material of strengthening decorative panel, compare with existing impregnated paper, the present invention has following marked improvement:
1. impregnated cloth is brown or black, has filled up the concavo-convex and cave defective of glued board, oriented structure chipboard or other kind wood-based plate face, and therefore, color is even, and density is high, the top layer minute surface is bright and clean;
2. can reduce the base material overlay film manufacturing procedure in one to two road, therefore, improve its production efficiency, reduce its production cost;
3. its ABRASION RESISTANCE reaches 600 changes the no grinning effect in back, and ABRASION RESISTANCE is apparently higher than general immersion tectorial paper commonly used, and the template that corrosion resistance is strong, good water-proof effect, ten minutes are adapted to repeated disassembled and assembled is used as overlay film;
Since its cost of material of the nonwoven fabric that adopts moderate, aboundresources is a kind of desirable fiber board for building shuttering film-coated fabrics.
