Abstract
The utility model relates to a colored weather resistant door and window plastic profile with a core layer, which relates to the building material field. The aging resistance and ultraviolet irradiation resistance f the prior plastic profile are poor, therefore the colored weather resistant layer is provided on the surface of the core layer of the utility model toward the outside, the modified polyvinyl chloride layer with higher weather resistance is provided on the three sides toward the inside, the core layer adopts the modified polyvinyl chloride layer with higher rigidity, and after molded with the co-extruding technology and enforced aging of 6000 hours, each performance is not changed basically, and the colored weather resistant door and window plastic profile has the advantages that the color is durable, the structure is simple, the processing is convenient, the cost is low, and the promotion is easy.
Description
Technical field
The utility model relates to building materials field, especially plastic material.
Background technology
Along with expanding economy, timber is as important constructional materials, and requirement sharply increases, caused the excessive exploitation of timber resources, and then destroyed human ecological environment of depending on for existence, need spend decades, go up the century-old time and could recover, so the consumption that reduces timber is the task of top priority.Various types of in addition plastic materials have obtained development at full speed, they have characteristics such as output is big, price is low, easy to process, in light weight, some plastic material can be used as the alternative of timber, their physical property, chemical property, processing characteristics all satisfy the requirement of building aspect to some extent, therefore it is feasible coming the direction of replacing wood with plastics, correct.At present existing many building units replace with plastics, but timber and plastics are two kinds of dissimilar materials after all, different characteristics and difference are arranged, lower as strength for polyvinyl chloride, ageing-resistant performance is low, and heat stability and UV resistant irradiation are all relatively poor, so will substitute timber, as the door and window materials, must improve it.
Summary of the invention
The purpose of this utility model for provide a kind of UV resistant irradiation, ageing-resistant, thermal stability is all good, the colored weather-proof plastic door-window section bar with sandwich layer simple in structure, easy to process.
The technical scheme that realizes the foregoing invention purpose is as follows:
Colored weather-proof plastic door-window section bar with sandwich layer, has the section bar sandwich layer, have the weather resisting colorful layer at the section bar sandwich layer towards outdoor surface, have aging-resistant layer towards three indoor sides, core layer thickness is 7-18mm, surperficial weather resisting colorful layer and side aging-resistant layer thickness are 0.2-0.5mm.
Surface weather resisting colorful layer material is that ASA is an acrylonitrile-styrene-acrylic ester copolymer, or modified PMMA is the polymethyl methyl esters, and sandwich layer is the modified polyvinyl chloride with higher stiffness, and the side aging-resistant layer is the modified polyvinyl chloride that has than high-weatherability.
Above-mentioned ASA has high chemical stability, water-fast, the material of anti-number of chemical effect, and product size is stable, and mechanical strength is higher, and good impact resistance and resistance to marring are arranged, and long-term light resistance is arranged and to the stability of temperature.Its heat distortion temperature is 87-104 ℃, refraction index 1.56-1.57
nD
20, molding shrinkage is 0.3-0.7%.PMMA has high heat stability, and decomposition temperature is＞200 ℃, has good weatherability, electrical insulating property, and the chemical-resistant reagent effect, the UV resistant effect has the transparency of height.Core material adopts the higher modified polyvinyl chloride of intensity, and side aging-resistant layer material adopts the higher modified polyvinyl chloride alkene plastics of ageing-resistant performance.
In the preparation, sandwich layer, surperficial weather resisting colorful layer and side aging-resistant layer are utilized screw extruder and extrusioning shaping of shaper.Obtain having existing higher-strength plastic door-window section bar than the high-weatherability resistance to ag(e)ing is arranged again.
The utlity model has following beneficial effect
1, mechanism is simple, easy to process;
2, color is durable, and specious have good weatherability, UV resistant irradiation, an ageing-resistant performance;
3, cost is low, is easy to promote.
Description of drawings
Fig. 1 is the colored weather-proof plastic door-window section bar structural representation that the utlity model has sandwich layer
The specific embodiment
Fig. 1 is a kind of embodiment of the present utility model.It has been key supporting role that the higher modified polyvinyl chloride of sandwich layer 1 usefulness intensity is made, thickness is 10mm, the higher modified polyvinyl chloride of side aging-resistant layer 2 usefulness ageing-resistant performances is made, thickness is 0.3mm, surface weather resisting colorful layer 3 usefulness ASA make, thickness is 0.4mm, once extrudes with screw extruder and shaper.After 6000 hours, every performance does not become substantially through forced aging.
Claims (2)
1, the colored weather-proof plastic door-window section bar that has sandwich layer, it is characterized by and have the section bar sandwich layer, has the weather resisting colorful layer at the section bar sandwich layer towards outdoor surface, have aging-resistant layer towards three indoor sides, core layer thickness is 7-18mm, surperficial weather resisting colorful layer and side aging-resistant layer thickness are 0.2-0.5mm.
2, the colored weather-proof plastic door-window section bar with sandwich layer according to claim 1, it is characterized by surperficial weather resisting colorful layer material is that ASA is an acrylonitrile-styrene-acrylic ester copolymer, or modified PMMA is the polymethyl methyl esters, sandwich layer is the modified polyvinyl chloride with higher stiffness, and the side aging-resistant layer is the modified polyvinyl chloride that has than high-weatherability.
