Embodiment 1

[0018] Embodiment 1: put the collected straw into the grass washing and impurity removal machine, and carry out the straw washing and impurity removal, which can wash the soil mixed with the straw, and remove impurities, leaves and other wastes in the straw; use the conveyor to send the cleaned straw to Enter the grass cutting machine, clean the straw and cut the straw, cut the straw into a length of 25mm according to the process requirements; use the screw conveyor to rub the chopped straw, and send the chopped straw to the silk rubbing machine to knead into fibers In this process, water should be added appropriately to ensure that the fiber dryness is 20%.

[0019] Grind the kneaded straw fiber. This process requires two high-consistency mills (high-consistency refiners) to be connected in series, and the screw conveyor is used to send the kneaded straw fiber to the first high-consistency mill, and water is added to grind the straw fiber. Add 90% water, automatically heat up...

Embodiment 2

[0020] Embodiment 2: the above method of obtaining straw fiber raw materials is the same; get 43 parts of straw fiber, 4 parts of water-based polyurethane, 0.02 part of blocked water-based isocyanate crosslinking agent, 0.03 part of carboxylated styrene-butadiene latex, 8 parts of fiber cotton and 15 parts of wood pulp, Proper amount of water is mixed to make raw materials. The raw materials are formed into thick sheets by multi-net molding. The thick sheets are pressed out of water, dried and cut to make 2.0mm fiberboards respectively. The remaining water is recycled and sedimented for reuse.

Embodiment 3

[0021] Embodiment 3: the above method of obtaining straw fiber raw materials is the same; get 47 parts of straw fiber, 5 parts of water-based polyurethane, 0.03 part of blocked water-based isocyanate crosslinking agent, 0.035 part of carboxylated styrene-butadiene latex, 9 parts of fiber cotton and 16 parts of wood pulp, Proper amount of water is mixed to make raw materials. The raw materials are formed into thick sheets by multi-net molding. The thick sheets are pressed out of water, dried and cut to make 2.0mm fiberboards respectively. The remaining water is recycled and sedimented for reuse.

Abstract

The invention discloses an environment-friendly insole fiberboard processing method. The environment-friendly insole fiberboard processing method comprises the steps that straw is cleaned, subjected to impurity removing, cut up by a straw cutter and then fed into a thread rolling machine, water is added, the straw is kneaded to be shaped like fibers, and the dryness of the fibers is 20-25%; two-time grinding is conducted, two or more high-concentration grinders are connected together in series, the kneaded straw fibers are fed into the first high-concentration grinder, water adding and grinding are conducted, the temperature is automatically increased to 40-50 DEG C, softened ground straw fibers are fed into the second high-concentration grinder, water adding and grinding are conducted, the temperature is automatically increased to 85-90 DEG C, and thus the softened ground straw fibers are further softened to prepare straw fiber raw materials, wherein water accounts for 85-95%; and thick pieces or thin pieces are formed by the straw fiber raw materials through multiple nets, water is squeezed out, drying and slitting are conducted, and thus insole fiberboards are prepared. Harmfulsubstances do not need to be discharged outwards in the whole process, a production technology is simple, the straw fibers are good in woodiness, the prepared straw fibers are high in dense quality, can replace traditional paperboards and are widely applied to the packaging industry and the decoration industry, and the environment influence caused by straw incineration is avoided thoroughly.

Description

technical field [0001] The invention belongs to the technical field of agriculture and relates to an environment-friendly processing method for midsole fiber boards. Background technique [0002] The midsole cardboard is a high-strength cardboard produced by adding wood pulp fiber and styrene-butadiene latex, which has good shapeability and air permeability. But prior art consumes wood pulp, is unfavorable for environmental protection. [0003] In recent years, straw and other crop stalks have become a new source of non-point source pollution in rural areas. Every summer harvest and autumn and winter, there is always a large amount of wheat, corn, rice straw and other straws burned in the field, which produces a lot of thick smoke, which not only becomes the bottleneck of rural environmental protection, but even affects the urban environment. According to relevant statistics, more than 700 million tons of straw can be generated in my country every year, becoming "waste" th...
