(1) after being mixed with 60 parts of ES short fibers by 40 parts of hemps, drop into feed bin, by mixed material through shredding, lapping, form the thin net of mixing natural fiber, alternately form stacked natural fiber stratum reticulare after laying;
(2) utilize jockey pulley to carry out lay PET non-woven fibre cloth, be overlying on stacked natural fiber stratum reticulare, the surface density of PET is 250g/m
2, acupuncture is carried out to stacked natural fiber stratum reticulare and non-woven scrim cloth;
(3) utilize jockey pulley hot melt adhesive film material EVA film to be covered on step (2) resulting materials, carry out hot pressing by after heating materials, hot pressing temperature scope is 190-200 DEG C, and pressure is 1.5MPa, forms continuous print natural fiber composite plate, cuts, packaging.
Table 1
Can see the increase along with natural fiber content by above-mentioned data, the hot strength raising gradually of material, elongation at break change is also not obvious, and bending strength is improving gradually.
Observed by comparison and can find for jute, sisal hemp, ramie, hemp, coconut palm palm fibre, bamboo fiber, flax fiber, relatively being difficult to fiber into the net is bamboo fiber and coconut fibre, thus these two kinds of natural-fiber composite material sheet materials add man-hour, need to add more thermoplastic resin fibre to facilitate into net.
Can be found by thickness contrast, with the addition of after PET enters as thermoplastic resin, the thickness of fiberboard increases, and intensity obviously declines.The fluffy degree of product can be increased, improve the sound absorption properties of material.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art, according to announcement of the present invention, do not depart from improvement that scope makes and amendment all should within protection scope of the present invention.
