Abstract
The invention discloses a method for manufacturing non-woven agricultural plastic mulching films, which comprises the following steps: uniformly mixing silk fibers and cotton fibers in a ratio of 50%; laying the obtained mixture on a wire gauze, and then flattening the mixture by using a heavy object; brushing a glue mixture on the positive and negative surfaces of the fibers, wherein the glue mixture comprises 5% of gelatin, 1.1% of epoxy resin, 6% of glycerol, 1.3% of sodium silicate and 1.5% of a penetrating agent; extruding the wire gauze laid with fibers by using a press roll, so that the wire gauze is uniformly soaked in the glue mixture and the bubbles are eliminated; heating the wire gauze to 160 DEG C in an oven so as to carry out curing molding; and carrying out demoulding on the obtained product so as to obtain a corresponding finished non-woven agricultural plastic mulching film product. The method disclosed by the invention has the advantages that: the production method is simple, the materials can be completely degraded, no pollution is caused to the environment, and silk-fibroins and celluloses have a fertilization enrichment effect on soil.
Description
Technical field
The present invention relates to a kind of nonwoven agricultural mulching.
Background technology
At present; Known mulch film mainly is made of plastics, and is widely used in agricultural because of it is cheap, with the continuous expansion of its usage amount and the growth of using year number; Plastic film residual in the farmland constantly accumulates; Its non-degradable has destroyed the soil environment of crop growth, begins to have a negative impact.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned deficiency, the manufacturing approach of a kind of nonwoven agricultural mulching that employing cotton fiber and silk fiber are processed.
The technical problem that the present invention will solve is to realize through following technical scheme: the present invention evenly mixes silk fiber and cotton fiber in 50% ratio proportioning, is laid on the wire netting, is paved into the back and flattens with weight; At the positive and negative brush coating of fiber, its glue proportioning is a gelatin 5%, epoxy resin 1.1%; Glycerine 6%, sodium silicate 1.3%, bleeding agent 1.5%; With the net of pressure roller extrusion laying fiber, make its even impregnation remove bubble side by side, in baking oven, be heated to 160 ℃ of curing moldings then; The demoulding can obtain corresponding finished product nonwoven agricultural mulching.
Advantage of the present invention is, its material can be degraded fully, and is free from environmental pollution, and silk-fibroin and cellulose have the getting fat effect to soil simultaneously.
Embodiment
In order to deepen to understanding of the present invention, will combine embodiment that the present invention is made further detailed description below, this embodiment only is used to explain the present invention, does not constitute the qualification to protection domain of the present invention.
A kind of nonwoven agricultural mulching of the present invention evenly mixes silk fiber and cotton fiber in 50% ratio proportioning, is laid on the wire netting, is paved into the back and flattens with weight; At the positive and negative brush coating of fiber, its glue proportioning is a gelatin 5%, epoxy resin 1.1%, glycerine 6%; Sodium silicate 1.3%, bleeding agent 1.5% with the net of pressure roller extrusion laying fiber, makes its even impregnation remove bubble side by side; In baking oven, be heated to 160 ℃ of curing moldings then, the demoulding can obtain corresponding finished product nonwoven agricultural mulching.
Claims (4)
1. the manufacturing approach of a nonwoven agricultural mulching is characterized in that: silk fiber and cotton fiber are evenly mixed, be laid on the wire netting; Being paved into the back flattens with weight; Lay the net of fiber at the positive and negative brush coating of fiber with the pressure roller extrusion, make its even impregnation remove bubble side by side, moulding then is heating and curing in baking oven; The demoulding can obtain corresponding finished product nonwoven agricultural mulching.
