Description

A kind of resistance to compression foam polyvinyl chloride pipe
Technical field
The present invention relates to foamed polyvinyl chloride technical field, particularly relate to a kind of resistance to compression foam polyvinyl chloride pipe.
Background technology
The pipeline carrying gas in exhaust equipment is referred to as airduct, and it has been linked to be an entirety the various equipment in system or parts.Airduct generally makes such as polyvinyl chloride pipe with ganoid material.Polrvinyl chloride is one of five big general-purpose plastics, has purposes widely in all conglomeraties such as building materials, packaging.Polyvinyl-chloride foam material more enjoys favor owing to having the features such as lightweight, heat insulation, sound insulation, high specific strength, insulation, but expanded material is while bringing cost to reduce, and mechanical performance declines, and significantly limit the application of PVC foam material." research of polrvinyl chloride-montmorillonite foam composite material " utilizes quaternary ammonium salt, season phosphonium salt and phosphoric acid ester intercalator and silane coupler and uses, prepare modified montmorillonoid, result shows when montmorillonite number is at 1-3phr, compression performance, tensile property, bending property are all improved, and heat distortion temperature and anti-flammability improve along with the increase of montmorillonite number.But montmorillonite adds excess, reunites in the base and makes expanded material Quality Down, and the tensile property of this expanded material, intensity, anti-flammability, resistance to chemical attack all have much room for improvement.
China is one of World banana main product state, 500,000,000 tons of Fructus Musae can be produced every year enjoy for people, but it is accompanied by the exploitation application that the side-products such as the banana stem of generation, Banana Leaf, banana caulo are not applied, only small part is processed to rope, gunnysack, handbag and other fancy product, the overwhelming majority is taken as rubbish and loses, this not only wastes resource, also pollutes environment.So extracting banana fiber from Banana Leaf to be prepared as composite, the economic development to China has great importance.Banana fiber can be divided into banana fiber and Banana Leaf fiber, the advantage that banana fiber has general bast-fibre, as intensity is high, extend little, fiber is thick and stiff, it is prone to humidity absorption and release, it is prone to the features such as dyeing, Banana Leaf fiber has excellent alkali resistant, phenol, formic acid, chloroform, acetone ability, it is added in pvc material reduce environmental pollution and brings huge economic benefit, and also the resistance to chemical attack of polrvinyl chloride can be improved, but it is directly added into the material property that can reduce polrvinyl chloride itself, limit its application, banana fiber must be modified, improve the interface compatibility of itself and polrvinyl chloride.
Summary of the invention
The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of resistance to compression foam polyvinyl chloride pipe.
The present invention is achieved by the following technical solutions:
A kind of resistance to compression foam polyvinyl chloride pipe, is made up of the raw material of following weight portion: sky bamboo fibre 3-4, Banana Leaf 20-25, silane coupling A 1631-1.5, azodicarbonamide 1.5-2, sodium bicarbonate 5-6, zinc oxide 0.2-0.3, polrvinyl chloride 100-110, zirconium oxide 1.5-1.8, calcined kaolin 2-3, dimethicone 2-3, Pulvis Talci 10-12, magnesium hydroxide 2-3, dinoctyl phthalate 2-3, antioxidant 1010 1-2, hydroxypropyl cellulose 0.6-0.8, butadiene-styrene rubber 3-4, deionized water are appropriate.
Described a kind of resistance to compression foam polyvinyl chloride pipe, is made up of step in detail below:
(1) Banana Leaf is cleaned up dry after use squeeze, bleach, clean, the method dried extraction banana fiber, then banana fiber and sky bamboo fibre carry out blending drafting, and to obtain composite fibre bar standby；Silane coupling A 163 is dissolved with the ethanol of 75%, is sufficiently mixed uniformly according to mass ratio 0.5:3, then composite fibre bar is impregnated in silane coupler solution with bath raio 1:10, be heated to solvent volatilization, standby after drying；
(2) zirconium oxide, calcined kaolin, magnesium hydroxide are ground to form the fine powder appropriate binding agent of addition and makes granule, granule was dried 200 mesh sieves standby；Hydroxypropyl cellulose, hydroxyethyl cellulose, polyvinylpyrrolidone are mixed according to mass ratio 1:2:1, is subsequently adding the water dissolution of total weight parts 22-25 times amount, be stirring evenly and then adding into above-mentioned standby granule, be heated to forming wet stock material while stirring standby；
(3) being added in the slurry of step (2) after modified composite fibre bar chopped step (1) prepared, ultrasonic disperse is uniform, is added to afterwards in baking oven dry；By the butadiene-styrene rubber acetone solution of 13-16 times amount, then being added in butadiene-styrene rubber solution by above-mentioned chopped strand, the uniform post-heating of ultrasonic disperse boils off solvent, obtains the mixture of rubber coated after drying；
(4) polrvinyl chloride and surplus materials thereof are added to mix homogeneously in high-speed mixer, it is then added in warm-up mill mixing plasticizing, temperature controls at 130-140 DEG C, add product prepared by step (3), being added in die cavity carry out moulded from foam after mix homogeneously, temperature controls at 185-190 DEG C, and the time is 2.5-3min, dwell pressure is 15-18MPa, and natural cooling is the most available.
The invention have the advantage that the present invention utilizes Banana Leaf fiber and the nandina ribbon of the modified blending of silane coupling A 163, hemicellulose and lignin component in Banana Leaf fiber is made to reduce, the combination degree of cellulose fibril weakens, easily untwist and deformation, improve elongation at break and hot strength, recycling hydroxypropyl, hydroxyethyl cellulose and polyvinylpyrrolidone process nano-mixture, its surface is made to form easy adsorption layer, it is attached to composite fibre bar surface and improves fire-retardant, wear-resisting, the performance such as fire-resistant, and utilize the compatibility that butadiene-styrene rubber and polrvinyl chloride are excellent, make ribbon good dispersion in polrvinyl chloride, do not reunite, reach to improve foam polyvinyl chloride pipe fire-retardant, wear-resisting, corrosion-resistant, light weight, the characteristic such as high-strength；The product price that the present invention produces is cheap, use raw material less, and production technology is simple, possesses higher-strength, and anti-pressure ability is strong, and fire resistance is high, and environmental protection is pollution-free, has a good application prospect when as exhaust duct.
