Description

Preparation method of solid wood grain leather film base material

Technical Field

The invention relates to a method for preparing a solid wood grain leather film base material, which completely takes long trunks as materials, and can prepare large-area wood grains which are naturally connected in parallel by accurately planing the film material aiming at the distribution characteristic of the wood grains so as to present real wood grains.

The industrial benefit of the film substrate, and particularly the high-efficiency cutting application in the growth characteristic of the tree, achieves the natural resource protection benefit with minimum consumption.

Background

The log-texture building material or board is applied to indoor decorative wall boards or furniture, can bring warm texture to the interior, has natural fragrance emission of woody fragrance, and is the highest-grade but highest-price application material.

Because trees grow slowly, if massive solid wood (such as fir, pine and the like) is used as plates in large quantity, besides the influence of damaging the earth environment by excessive felling, the massive solid wood with enough area and thickness is difficult to obtain, the price is relatively more and more expensive, and the damage to the nature is quite serious and cannot be ignored absolutely; therefore, there are many alternative products on the market today that aim to replace the appearance of solid wood, such as: plywood or foam board, etc.

The veneer with wood grains is usually pasted on the outer layer of the plywood or the foam board, but the veneer is printed by a printing machine, the repeatability of the grains is high, and the veneer is quite unnatural when being applied to decoration. In addition, the printing veneer lacks the multiple effects that the original wood can absorb infrared rays and ultraviolet rays and emit natural warm color series and natural log fragrance.

In order to solve this problem, manufacturers have developed natural wood veneers obtained by cutting wood in chord, rotary, radial or radial directions, and then bonded to the outer layer of the plywood or the foam board or the top layer of the non-woven fabric to form a wood grain veneer for bonding.

However, the traditional veneer splitting technology cannot draw materials according to the growth veins of the wood, so that the wood grain boards adhered to the whole surface cannot avoid the scattered and cracked natural wood grain visual effect, and particularly when the wood grain boards are laid on large-size and large-area board surfaces or wall surfaces, the manufacturing means has the condition that the grain repeatability is high or the veneer grains are extremely unnatural, but the installation effect of the natural wood is lost, so that the wood grain boards are obviously not beneficial.

In another mode, the wood veneer is adhered to a splint or a hard material by using the technology of a scientific wood veneer; however, the technical veneers need to be pre-treated before being attached, so that the procedure is complicated, the cost is higher, the technical veneers are much thicker and heavier than natural veneers, and the technical veneers are labor-consuming and inconvenient to lay and construct.

How to improve the wood bark cutting technology and consider taking out materials with high efficiency and maintaining the heaven-resource tree resources is a problem that relevant manufacturers need to solve actively together.

Please refer to fig. 2, fig. 3, and fig. 4: the invention relates to a method for preparing a solid wood grain leather film substrate, which comprises the steps of marking a rectangular or circle center-shaped central waste material part 21 on a horizontally placed long trunk 2 by taking the cross section of an annual ring as the center; the upper and lower sides of the waste material part 21 are wide plate areas 2A, and the left and right sides of the waste material part 21 are narrow plate areas 2B;

the method comprises the steps of firstly, horizontally sectioning layer by setting equal thickness to obtain a multilayer plate body (a horizontal cutter S1), then removing narrow materials 2C with insufficient width at the top and bottom sides of the wide plate area 2A at the upper and lower sides, and removing residual edge materials 2D with the left and right sides trimmed to be straight edges, so as to cut the wide main plate 22 with multiple layers and equal thickness, vertical joint surfaces at two sides and the characteristic of main wood grains of tree species;

then, aiming at the middle narrow plate area 2B, longitudinally cutting (a longitudinal cutter S2) by cutting the width of the waste material part 21, and removing the left and right trimming to form straight edges 2D, thus obtaining a plurality of layers of narrow side plates 23 with equal thickness, vertical joint surfaces at two sides and continuous straight grain characteristics;

fig. 2 shows a longitudinal cutting (longitudinal cutter S2) type of the planned rectangular scrap part 21, which simplifies the cutting process but may have a problem of low material taking rate (narrow width of the side plate 23); fig. 3 shows a longitudinal cut (longitudinal cutter S3) of the planned circle-center shaped scrap part 21, the cutting process of which is performed by lane cutting according to the actual width of the actual scrap part 21; the cutting process is more, but the material taking rate is higher (the width of the side plate 23 can be wider);
