Abstract
The manufacture of plastics-steel shapes for door and window includes the following steps successively: mixing separately the hard and soft plastic materials in certain ratio in a mixer; plasticizing the hard plastic material and the soft plastic material in main extruder and auxiliary extruder separately; injecting the plasticized materials via different flow channels into mold to form sealing strips of soft plastic and shape bodies of hard plastic combined together; and drawing out and cutting the cooled and set shapes. The hard shapes has integrally combined soft sealing strips.
Description
Technical field:
The present invention is relevant with the method for making plastics-steel shapes for door and window with extruder.
Background technology:
Existing method with extruder manufacturing plastics-steel shapes for door and window uses a screw extruder that a kind of material that plastifies into pasty state is clamp-oned die forming from its runner hole, the whole material unanimity of section bar after the shaping, need make in addition in the caulking groove of sealing strip embedding section bar, the door and window of making so just has sealing property, the manufacturing process complexity.In addition, the sealing strip of the door-window section bar of making like this is easily aging, come off, and variable color, service life is short, poor sealing performance.
The content of invention:
It is simple to the purpose of this invention is to provide a kind of manufacturing process, is formed with the method for the manufacturing plastics-steel shapes for door and window of the different sealing strip of material on the product body.
The present invention is achieved in that
The present invention makes the method for plastics-steel shapes for door and window, in turn includes the following steps:
(1) hard and flexible plastic raw material are added the extruder hopper behind the process batch mixer batch mixing respectively by proportioning;
(2) the rigid plastics raw material enters main extruder, and the flexible plastic raw material enters secondary extruder, and material progressively plastifies into pasty material in extruder barrel;
(3) material that plastifies in the major and minor extruder is gone into mould from its runner orifice flow respectively simultaneously, and the flexible plastic material is configured as sealing strip in mould, and the rigid plastics material is configured as the section bar body, and both bond together in mould;
(4) with the section bar traction cutting of cooling and shaping, the soft sealing strip that is connected as a single entity is arranged on the hard section bar.
Material temperature is 95 ℃-210 ℃ in the main extruder of the present invention, and material temperature is 110 ℃-160 ℃ in the secondary extruder.
Technology of the present invention is simple, and production cost is low, and product does not need to dispose in addition sealing strip, the heat insulating ability of the plastic-steel door and window of making, anti-air and rain penetration, and anti-wind pressure, sound insulation, corrosion resistance, weather resisteant, anti-natural aging is good.Air-tightness in being up to state standards respectively, resisting wind press capacity primary standard, rain penetration, the sound insulation fourth stage.Has color coordination.And it is easily aging to have solved the sealing strip that section bar that traditional handicraft makes is provided with, and comes off and the problem of variable color.Install simultaneously simple and easy, convenient, quick at door and window.
The specific embodiment:
Capital equipment required for the present invention is two PVC heat refining mixers, two PVC cooling mixing machines, two two (list) screw extruders, a mold, a Vacuum shaping platform, a traction cutting machine, a roll-over table.
Production process of the present invention is as follows:
---heat is mixed, and------material loading---extrudes that---------finished product gathers materials die forming to draw---fixed length cutting---in vacuum cooled typing to cold mixing to batching.
The present invention is a primary raw material with polyvinyl chloride (PVC) resin, add the stabilizing agent of different proportion, modifier, colouring agent, filler, ultra-violet absorber, auxiliary agents such as fire retardant mix mixing one-tenth soft pvc plastic of unit and hard PVC plastics materials through one group respectively, are extruded into cooling forming in the same set of mould through the extrusion cavities of a screw extruder respectively again, the extrusion temperature of flexible PVC material is 140 ℃, be configured as sealing strip in mould, the extrusion temperature of hard PVC material is 160 ℃, is configured as the section bar body in mould, two kinds of materials enter mould by two runner holes, be bonded as one after in mould, being shaped, by cooling, Vacuum shaping, make fixed length cutting by the traction cutting machine, produce various qualified products.
Claims (2)
1, make the method for plastics-steel shapes for door and window, in turn include the following steps:
(1) hard and flexible plastic raw material are added the extruder hopper behind the process batch mixer batch mixing respectively by proportioning;
(2) the rigid plastics raw material enters main extruder, and the flexible plastic raw material enters secondary extruder, and material progressively plastifies into pasty material in extruder barrel;
(3) material that plastifies in the major and minor extruder is gone into mould from its runner orifice flow respectively simultaneously, and the flexible plastic material is configured as sealing strip in mould, and the rigid plastics material is configured as the section bar body, and both bond together in mould;
(4) with the section bar traction cutting of cooling and shaping, the soft sealing strip that is connected as a single entity is arranged on the hard section bar.
2, method according to claim 1 is characterized in that material temperature is 95 ℃-210 ℃ in the main extruder, and material temperature is 110 ℃-160 ℃ in the secondary extruder.
