Synthetic-resin window sectional materials with multiple-color and three-dimensional surface figure and producing apparatus thereof

Abstract

A section with multi-color concave-convex pattern on at least one surface for window is made up of synthetic resin. Its preparing apparatus is composed of extruder, die set, auxiliary extruder, vacuum cooling unit and embossing unit.

Description

technical field [0001] The invention relates to a synthetic resin window profile with multi-color and three-dimensional pattern surface and its production equipment, in particular to a kind of resin that can use a mold and an auxiliary extruder to extrude resins of other materials, so as to produce more than two kinds of different profiles. Color, and use the pattern roller installed on the mold and other auxiliary devices to produce synthetic resin window profiles with multi-color and three-dimensional pattern surfaces and production equipment with different patterns, which can improve the aesthetics and service life of synthetic resin windows. Background technique [0002] figure 1 It is a schematic diagram of extrusion molding equipment for synthetic resin window profiles in the prior art. Figure 2a and Figure 2b It is a front view and a longitudinal sectional view of a common mold for producing a prior art synthetic resin window profile. image 3 It is a three-dimen...

Problems solved by technology

like image 3 As shown, the surface of the widely used synthetic resin window profile 3b is mostly single color at present, when the window profile 3b manufactured by the molten resin of a single material is exposed outdoors for a long time or is affected by sunlight and other weather factors , the surface of the window profile 3b located on the outdoor side will be eroded, and its service life will be greatly shortened compared with the surface of the window profile 3b located on the indoor side

In addition, when the surface of this window profile 3b is processed by a mould, since the molten resin on the surface contains materials such as plasticizers, water marks or stripes often appear on the smooth surface, and the gloss is uneven, which will greatly affect the Affects the appearance of window profile 3b

Although the production process of using a patterned roller to produce a concave-convex effect on the surface so that the product has a three-dimensional effect and becomes more beautiful has been widely used in the manufacture of double-layer products such as wallpaper and substrates, but in the injection extrusion of synthetic resin window profiles There is no public report on the production process and production equipment that directly use the patterned roller in the production process to make the product have a three-dimensional effect.

In addition, the traditional method of making the surface of the window profile with color and three-dimensional effect is mainly to first produce a synthetic resin window profile with no three-dimensional effect on the surface, and then color the surface of the formed window profile or use an adhesive to stick a film or sheet to it. The surface of the window profile, so that the surface of the window profile has a variety of colors and three-dimensional effects, but it usually needs to be heated to cure the pigment when painting, which will cause the deformation of the window profile; The production process is very complex due to the need for special follow-up processes
