Abstract
The invention discloses composite technique for multilayer PP sheet material without adhesive agent and comprises steps: select PP plastic with even particle diameter and heat to 210Deg~220Deg and fusing; extrude sheet base body; coat biaxial tension PP printing membrane on single side or two sides of aforementioned base body and press to multilayer of 1~3 layers PP composite sheet material by biaxial pinch roll at 105Deg~110Deg. The technique adds no any adhesive agent and other addition agent; all is physical method; the product is safe, environmental protection and without peeling phenomena after service for long time.
Description
Technical field
The present invention relates to material processing technique, particularly a kind of non-adhesive compounding technology for multilayer polypropylene sheets.
Background technology
Multilayer polypropylene sheets is a kind of chemical materials commonly used, the processing technology of conventional multilayer polypropylene sheets is to adopt each strata propylene sheet material to be sticked with glue agent is bonding to form, often contain organic solvents such as a large amount of cyanides, toluene in the adhesive, and remain in sheet surface, this product is not suitable for as the directly external packing of contact food, and use it for anything else and also can discharge pernicious gas, environment and production operation personnel all there is great harm, after long-time the use, the phenomenon that multilayer polypropylene sheets also can occur peeling off between each layer.
Summary of the invention
Technical problem to be solved by this invention provides a kind of non-adhesive compounding technology for multilayer polypropylene sheets, utilizes the multilayer polypropylene sheets of this explained hereafter, have use extensively, the characteristics of safety, environmental protection.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of non-adhesive compounding technology for multilayer polypropylene sheets, described combination process comprises the steps:
A, select for use particle diameter comparatively uniformly the polypropylene plastics grain be heated to 210 ℃～220 ℃, make plastic pellet be in molten condition;
B, the polypropylene that will be in molten state are extruded into sheet base through extruding machine;
C, one-sided or both sides apply the Biaxially oriented polypropylene print film be squeezed into the multi-layer polypropylene composite sheet through two-way nip rolls under 105 ℃～110 ℃ temperature with the sheet base in the above-mentioned steps.
Wherein, described sheet base comprises 1～3 strata propylene sheet material.
The beneficial effect that the present invention can reach is: production technology of the present invention, do not add any adhesive and other additives in its process, and all be that physical method processes, products obtained therefrom safety, environmental protection, and the long-time phenomenon that also can not occur peeling off of using.
The specific embodiment
Non-adhesive compounding technology for multilayer polypropylene sheets comprises the steps:
A, select for use particle diameter comparatively uniformly the polypropylene plastics grain be heated to 210 ℃～220 ℃, make plastic pellet be in molten condition;
B, the polypropylene that will be in molten state are extruded into sheet base through extruding machine, and sheet base is 2 strata propylene sheet materials;
C, the sheet base both sides in the above-mentioned steps are applied the Biaxially oriented polypropylene print film under 105 ℃～110 ℃ temperature, be squeezed into the multi-layer polypropylene composite sheet through two-way nip rolls.
Claims (2)
1, a kind of non-adhesive compounding technology for multilayer polypropylene sheets is characterized in that: described combination process comprises the steps:
A, select for use particle diameter comparatively uniformly the polypropylene plastics grain be heated to 210 ℃～220 ℃, make plastic pellet be in molten condition;
