Abstract
A hard polyvinyl chloride tube for supplying water in building in prepared from polyvinyl chloride resin, stabilizer, lubricant, acrylate resin and nano-material through high-speed mixing, injection moulding and cooling. Another preparing method is also disclosed.
Description
Technical field
The invention belongs to the materials for construction field, particularly a kind of building water supply rigid polyvinyl chloride (UPVC) pipe fitting and manufacture method thereof.
Background technique
The building water supply pipe fitting is the link that comprises pipe coupling etc., is widely used in the building water supply industry.Compare with the feedwater pipe fitting of other manufacture of materials, advantages such as rigid polyvinyl chloride (UPVC) pipe fitting has easy processing, bonding convenience, price is low, appearance quality good, resistance to water-flow is little, but, the decision of the structure of molecule of PVC the PVC material have bigger fragility, especially low temperature brittleness is big.Therefore, when producing building water supply, must add impact modifier to improve the impact toughness of product with rigid polyvinyl chloride (UPVC) pipe fitting, impact modifier is generally thermoplastic elastic body, as nitrile butadiene rubber (NBR), haloflex (CPE) etc., though the adding of this class material can improve the impact toughness of rigid polyvinyl chloride (UPVC) product, but can cause the reduction in strength of rigid polyvinyl chloride (UPVC) material, the water pressure resistance decreased performance that causes the pipe fitting produced, the feedwater pipe fitting in use breaks easily.The water pressure resistance performance and the anti-impact toughness of rigid polyvinyl chloride (UPVC) feedwater pipe fitting are the subject matter that the present invention will solve.
Summary of the invention
The objective of the invention is to utilize the synergy of acrylate and nanometer material to solve the compressive strength of rigid polyvinyl chloride (UPVC) feedwater pipe fitting and the contradiction between toughness.Provide a kind of and not only had good resistance towards toughness but also rigid polyvinyl chloride (UPVC) pipe fitting with higher compressive strength.
The objective of the invention is to realize by following proposal that a kind of building water supply is with rigid polyvinyl chloride (UPVC) pipe fitting, it contains 100 parts of Corvics, 2～5 parts of stabilizers, 0～1.5 part of oiling agent, 1～5 part of acrylate, 2～10 parts of nanometer materials.
Described nanometer material is that any described nanometer material of nano-calcium carbonate, organo montmorillonite, nano aluminium oxide has the size of a direction at least less than 100 nanometers.
Described stabilizer is any of organic tin stabilizer, calcium-zinc composite stabilizing agent, lead salt compound stabilizer.
Described oiling agent is at least a of stearic acid, calcium stearate, zine stearate, paraffin, Tissuemat E, OPE.
The building water supply that the present invention relates to can adopt following two kinds of explained hereafter with rigid polyvinyl chloride (UPVC) pipe fitting.
Technology one is added to polyvinyl chloride resin, stabilizer, oiling agent, acrylate in the high-speed mixer in proportion earlier and mixes; After temperature of charge reaches 90 ℃～100 ℃ in the mixing machine, and then nanometer material added in the high-speed mixer; After temperature of charge in high-speed mixer is raised to 115～125 ℃, the material in the high-speed mixer is put in the cooling mixing machine; After 45 ℃ of material cooling and mixing, the material of cooling mixing machine is discharged; Material after the cooling and mixing is added in rigid polyvinyl chloride (UPVC) special injection molding machine, and the injector barrel temperature is controlled at 165 ℃～185 ℃; The material of fusion plastification is injected in the closed mould, after the material temperature in the mould is cooled to below 45 ℃, mould is opened the taking-up goods, promptly obtain building water supply rigid polyvinyl chloride (UPVC) pipe fitting that the present invention relates to.According to the difference of pipe fitting specification, the suitable adjustment of the process conditions of injection process (comprising injection volume, inject time, dwell time, cool time, injection pressure) needs.Adopt this explained hereafter building water supply with rigid polyvinyl chloride (UPVC) pipe fitting, to having relatively high expectations of the plasticizing capacity of injection molding machine.
Technology two is added to polyvinyl chloride resin, stabilizer, oiling agent, acrylate in the high-speed mixer in proportion earlier and mixes; After temperature of charge reaches 90 ℃～100 ℃ in the mixing machine, and then nanometer material added in the high-speed mixer; After temperature of charge in high-speed mixer is raised to 115～125 ℃, the material in the high-speed mixer is put in the cooling mixing machine; After 45 ℃ of material cooling and mixing, the material of cooling mixing machine is discharged; The material that mixes is added in the extruding granulator, and extruder barrel and head temperature are controlled at 165 ℃～185 ℃; With the pellet cool drying that makes, dried rigid polyvinyl chloride (UPVC) pellet is added in the injector; The injector barrel temperature is controlled at 165 ℃～180 ℃, the material of fusion plastification injects in the closed mould, material temperature in the mould is cooled to below 45 ℃, and mould is opened the taking-up goods, promptly obtains building water supply rigid polyvinyl chloride (UPVC) pipe fitting that the present invention relates to.According to the difference of pipe fitting specification, the suitable adjustment of the process conditions of injection process (comprising injection volume, inject time, dwell time, cool time, injection pressure) needs.With this explained hereafter pipe fitting the time, because the PVC mixture is by preplasticizing, so this technology is lower relatively than technology one to the requirement of the plasticizing capacity of injection molding machine.
With the building water supply of prescription provided by the invention and explained hereafter with rigid polyvinyl chloride (UPVC) pipe fitting the mechanical property and the building water supply of micro-calcium carbonate modification see Table 1 with the mechanical property contrast of rigid polyvinyl chloride (UPVC) pipe fitting.
