Abstract

The utility model discloses a two-color tectorial membrane PVC sectional material for doors and windows, which comprises a PVC sectional material main body. An entirely chromatic outer wall of PVC sectional material is joined on the PVC sectional material main body via the means of two-color coextrusion and integral forming, and a layer of protective coating the color of which is similar to that of the outer wall is coated on the outer surface of the outer wall of sectional material. Compared with the entirely white sectional material, the technical scheme has the advantages with colorful diversity that compared with the entirely chromatic sectional material, the PVC sectional material of two-color coextrusion can form combinations with different colors on two visible planes indoor and outdoor, and can be arranged by freely choosing different color combinations according to the requirements of interior decoration. Compared with the chromatic thin layer coextrusion of visible outer layers, the utility model is more reinforced in assembly property, practicability and entire esthetics. And as the sectional material and the sectional material outer wall are combined via the same material, the combination is firm. In addition, a layer of the protective coating with the color is similar to that of the outer wall is additionally coated on the surface of the outer wall of PVC sectional material, thereby increasing the ageing resistance and abrasion resistance of the sectional material.

Description

A kind of double-colored overlay film PVC door-window section bar

Technical field

The utility model belongs to PVC section bar field, particularly relates to a kind of double-colored overlay film PVC door-window section bar.

Background technology

Along with popularizing of PVC plastic door-window product, people have proposed more, higher requirement to it, wish to break through traditional single white, develop to colouring.Originally, the section bar industry is for the requirement of market colorize, also by technological innovation and technological transformation, take products such as multicolored entire body, the outer colored thin layer co-extrusion of visible surface to answer market back and forth, but some problems have all appearred in the market test through after a while, and effect is not very desirable.Entire body white can adapt to the various environment and the general layout of house integral body, the various interior decoration colors of also arranging in pairs or groups simultaneously, but lack color sensation, the vision trend is flat; Multicolored entire body from the house external overall, gives the house splendid color sensation, gives the house with vigor, belong to apt word added to clinch the point, but entire body look kind is single, can't take into account interior decoration usually, indoor tone can't be arranged in pairs or groups be in harmonious proportion sometimes even feels dazzling; The outer colored thin layer co-extrusion of visible surface is taken into account inside and outside this kind product seems, and has gathered the advantage of top two kinds of products, but it is also very obvious to play defective, and colored outer wear-out failure easily will be exposed the color of bottom surface after the outer wearing and tearing, especially form lapping defect easily at joint, influence visual sense of beauty.

Summary of the invention

In order to solve above-mentioned technical problem, the purpose of this utility model provides a kind of double-colored overlay film PVC door-window section bar, make section bar different colors can arranged, and solve multicolored entire body and the outer colored thin layer co-extrusion section bar collocation of colour difficulty of visible surface, the problem such as background color of exposing easy to wear towards two visible surfaces of indoor and outdoors.

To achieve the above object, the utility model has adopted following technical scheme:

A kind of double-colored overlay film PVC door-window section bar; described section bar comprises PVC section bar main body; engage an entire body for colored PVC section bar outer wall by the one-body molded mode of bicolor co-extrusion on the PVC section bar main body, be covered with the close diaphragm of one deck color on the external surface of section bar outer wall.

Said protection film can be the PMMA film, also can be pvdf membrane.

The utility model is compared with entire body white section bar owing to adopted above technical scheme, has had the diversified advantage of color; Compare with the multicolored entire body section bar, this bicolor co-extrusion PVC section bar can form the combination of different colours at indoor, outdoor two visible surfaces, can choose at random different color combination according to the interior decoration needs and arrange; Compare with the outer colored thin layer co-extrusion of visible surface, its assembling performance, practicality and overall aesthetic are more strengthened; And, because section bar main body and section bar outer wall are that same material is in conjunction with firm; In addition, add in the PVC of colour section bar outer wall surface and to cover the close diaphragm of one deck color, improved the resistance to ag(e)ing and the abrasion resistance of section bar.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the A place partial enlarged drawing among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is made a detailed explanation.

Embodiment 1:

A kind of double-colored PVC door-window section bar as shown in Figure 1 and Figure 2; described section bar comprises PVC section bar main body 3; engage an entire body for colored PVC section bar outer wall 2 by the one-body molded mode of bicolor co-extrusion on the PVC section bar main body 3, cover the close diaphragm of one deck color 1 by binding agent 4 on the external surface of section bar outer wall 2.Said protection film 1 is PMMA film or pvdf membrane etc.

During manufacturing, design two different prescriptions, the section bar outer wall is a coloured formulations, and other still is white or needed other color that is different from the section bar outer wall; The dry blend of coloured formulations is passed through a co-extrusion machine, mix at the bicolor co-extrusion mould place of being close to the exit with white (other color) dry blend, moulding and adhesion merge; Just form the double-colored laminated section bar that is structure as a whole behind the cooling and shaping; Cover one deck PMMA film close (or pvdf membrane etc.) at the external surface of section bar outer wall again after becoming a useful person with its color.

The section bar outer wall of above-mentioned colour not only can be that section bar also can be that section bar is towards indoor one side towards outdoor one side.

Claims

1. double-colored overlay film PVC door-window section bar; it is characterized in that; described section bar comprises PVC section bar main body (3); section bar main body (3) goes up by the one-body molded mode of bicolor co-extrusion and engages an entire body for colored PVC section bar outer wall (2), is covered with the close diaphragm of one deck color (1) on the external surface of section bar outer wall (2).
