Description

A kind of high-performance poly vinyl chloride pipe for exhaust equipment
Technical field
The present invention relates to foamed polyvinyl chloride technical field, particularly relate to a kind of high-performance poly vinyl chloride pipe for exhaust equipment.
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 high-performance poly vinyl chloride pipe for exhaust equipment.
The present invention is achieved by the following technical solutions:
A kind of high-performance poly vinyl chloride pipe for exhaust equipment, it is made up of the raw material of following weight portion: Banana Leaf 23-25, polytetrafluoroethylene fibre 3.4-4, 0.2% monoalkoxytitanates coupling agent 1-1.5, azodicarbonamide 1.5-2, sodium bicarbonate 5-6, zinc oxide 0.2-0.3, EVA resin 4-5, schmigel 1.8-2, stone powder 2.3-2.5, nano barium phthalate 1.3-1.6, precipitated calcium carbonate 6-9, turkey red oil 2-3, polrvinyl chloride 100-110, fatty alcohol-polyoxyethylene ether 0.3-0.4, calcium oxide 4-5, ABS resin 7-8, polyoxyethylene wax 0.7-1, ethylene glycol 10-12, silane coupler kh550 0.2-0.3, deionized water is appropriate.
Described a kind of high-performance poly vinyl chloride pipe for exhaust equipment, is made up of step in detail below:
(1) Banana Leaf is cleaned up dry after use squeeze, bleach, clean, the method dried extracts banana fiber, then banana fiber and polytetrafluoroethylene fibre carried out blending drafting be added in 105 DEG C of drying baker dry；In the deionized water of calcium oxide is dissolved in 22-25 times amount 35-40 DEG C, after fully dissolving, add blend fibre bar, 0.2% monoalkoxytitanates coupling agent and fatty alcohol-polyoxyethylene ether, be subsequently placed in processor for ultrasonic wave process 30-40min；
(2) by stone powder, nano barium phthalate and schmigel addition concentration be 75% ethylene glycol in make suspension, add silane coupler kh550 while stirring, again product prepared by step (1) is added thereto, continue ultrasonic 20-30min, then it is placed in vacuum drying oven and is dried, after natural cooling, be ground into fine powder；
(3) add polyoxyethylene wax after being heated to ABS resin melting, add fine powder prepared by step (2), extrusion granulator after mixing and stirring, naturally cool to room temperature；
(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 135-145 DEG C, add product prepared by step (3), being added in die cavity carry out moulded from foam after mix homogeneously, temperature controls at 180-190 DEG C, and the time is 2.6-3min, dwell pressure is 16-18MPa, and natural cooling is the most available.
The invention have the advantage that and then reaching the present invention utilizes calcium oxide solution to process Banana Leaf fiber and polytetrafluoroethylene fibre bar, improve activity and the toughness of fiber surface, add coupling agent and penetrating agent again, make the compositions such as nano barium phthalate more perfect to the surface action of fiber, improve its elongation at break, the characteristic such as hot strength and fireproof wear-resisting, and utilize the good compatibility between ABS resin and polrvinyl chloride, improve ribbon dispersibility in polrvinyl chloride, reach to improve foam polyvinyl chloride pipe super abrasive, corrosion-resistant, high-strength, the characteristic such as heat-resisting；The polychloroethylene pipes that the present invention prepares has the feature of high tenacity, high mechanical properties, is better than market like product, and the airduct as exhaust equipment has a good application prospect.
