CN101116994A - Method for preparing novel vegetation composite tube - Google Patents

Abstract

The invention discloses a production method of a new type complex pipe of grass and wood, the stalk of the crop should be smashed of over 50 mesh as the main material, and 1000 shares main material, 250 shares stickiness adhesive and 0.5 shares paper making intensifier should be mixed evenly and be made into the pipe material: then the material is formed by extrusion molding in a forming machine and made into complex pipes of high density fibre. Compared with paper pipes of same thickness, the manufacture cost of the complex pipe of high density fibre of the invention is reduced by more than 30 percent; the pipe has high rigidity and proper temper. The invention is capable of producing complex pipes of high density fibre of high quality, with high economic value and notable social effect.

Description

A kind of preparation method of novel vegetation composite tube

Technical field

The present invention relates to a kind of preparation method of tubing.Be particularly related to a kind of preparation method of novel vegetation composite tube.

Background technology

At present, as the paper industry refill, the textile industry refill, firecrackers, salvo body, and the tubing of smelting industry thermocouple temperature measurement pipe etc. generally rolls with paper and forms.This way mainly contains two shortcomings, and the first, manufacturing cost is higher; The second, consume a large amount of paper making raw materials indirectly, such as timber, bamboo etc., this with do not conform to the theory of building a conservation-minded society that various circles of society advocate energetically when former government.

On the other hand, but pile up like a mountain for resources such as a large amount of stalks in rural area, green grass, sawdust, because of can not get effectively being used as fuel, fertilizer etc., not only causes waste, also produces environmental pollution to a certain degree.

Summary of the invention

The preparation method who the purpose of this invention is to provide a kind of novel vegetation composite tube, overcome existing tubing cost height made of paper, consume the defective of narrow resources, mainly solve with stalk, green grass, sawdust etc. and make toughness and rigidity problem in the main feedstock production high-density fiber composite pipe.

The technical solution adopted in the present invention is as follows.

A kind of preparation method of novel vegetation composite tube is characterized in that:

The first step: with the crop material of drying, perhaps grass, perhaps leaf bark, perhaps sawdust, perhaps a kind of in the line suede or more than one press the arbitrary proportion cooperation, are crushed to more than 25 orders through pulverizer except that line suede, make long fiber fraction; With the peanut skin of drying, perhaps a kind of in the threshing corn rod or two kinds are pressed arbitrary proportion and are cooperated, and are crushed to more than 50 orders through pulverizer, make short fiber component; Long fiber fraction and short fiber component are according to 100: the ratio of 61-70 is mixed and made into the major ingredient component;

Second step: with 1000 parts of major ingredient components, 250 parts of adhesive, paper making intensifier mixes for 0.5 part, makes the tubing raw material;

The 3rd step: at first make-up machine is heated to 220 ℃, with the extrusion molding in make-up machine of tubing raw material, makes the high-density fiber composite pipe then;

Wherein, crop material mainly refers to bar, the leaf, climing of wheat, corn, paddy, peanut, and the solid content of paper making intensifier is 8%.

The present invention has following characteristics: compare with identical wall thickness system paper tube material, high-density fiber composite pipe manufacturing cost of the present invention reduces more than 30%, and rigidity is higher, and toughness is suitable.The present invention can prepare high-quality high-density fiber multiple tube by the method for comprehensive utilization of waste materials, not only has higher economic value, and obvious social benefit.

The specific embodiment

The present invention will be further described below in conjunction with concrete preparation embodiment.

Embodiment

The first step: with the crop material of drying, perhaps grass, perhaps leaf bark, perhaps sawdust, perhaps a kind of in the line suede or more than one press the arbitrary proportion cooperation, are crushed to more than 25 orders through pulverizer except that line suede, make long fiber fraction; With the peanut skin of drying, perhaps a kind of in the threshing corn rod or two kinds are pressed arbitrary proportion and are cooperated, and are crushed to more than 50 orders through pulverizer, make short fiber component; Long fiber fraction and short fiber component are mixed and made into the major ingredient component according to 100: 65 ratio;

Second step: with 1000 parts of major ingredient components, 250 parts of adhesive, paper making intensifier mixes for 0.5 part, makes the tubing raw material;

The 3rd step: at first make-up machine is heated to 220 ℃, with the extrusion molding in make-up machine of tubing raw material, makes the high-density fiber composite pipe then;

Wherein, crop material mainly refers to bar, the leaf, climing of wheat, corn, paddy, peanut, and the solid content of paper making intensifier is 8%.
