Abstract
The invention discloses a PE membrane compounding process which comprises the following procedures: blending a base coating, recoiling, performing corona treatment, performing base coating, drying, performing finish coating, drying the finish coating, and coiling. By adopting the mode, the fusion and polymerization property of a PE membrane is improved, the PE membrane is relatively high in transparency, the tension of the coiling procedure can be controlled, the mass of the PE membrane is effectively reduced, and due to the adoption of the electric spark treatment process, the PE membrane is good in adhesion solidness and compounding strength, and the wet-resistance and the thermal resistance of the PE membrane are also improved.
Description
Technical field
The present invention relates to field of thin film fabrication field, particularly a kind of PE membrane compound technology.
Background technology
High density polyethylene (HDPE) is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.PE has excellent resistance to great majority life and the characteristic of chemicals for industrial use.Non-hygroscopic and the steam-preventing had of this polymer, can be used for packing purposes.PE has good electrical property, and particularly dielectric strength is high, makes it be applicable to electric wire very much.Existing PE black and white is double-colored waits Coloured film, at waterproofing membrane production with in using, because of the yellow used oil in pitch, penetrate into the surface of PE film, film being turned yellow, affects outward appearance, depositing nitrogen element aborning to being coated with the catalyst poisoning phenomenon caused in silicone oil process simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide one, to solve the above-mentioned multinomial defect caused in prior art.
For achieving the above object, the invention provides following technical scheme: a kind of PE membrane compound technology, is characterized in that, comprise the following steps:
1) masking liquid allotment, comprising: the agent of solvent-borne type acrylic adhesive and ethyl acetate are mixed with the ratio of 1:3 volume ratio, then PVDC emulsion and water is mixed with the ratio of 1:1 volume ratio, then both is mixed;
2) film raw material is unreeled with permanent pulling force;
3) sided corona treatment is carried out to the film after unreeling;
4) film after sided corona treatment is carried out primary coat by metal chromium plating anilox roll;
5) masking liquid is applied to film bottom surface, completes primary coat operation, hot air dries is carried out to film;
6) after completing drying, masking liquid is applied to film bottom surface, finished surface is coated with operation;
7) facial mask is carried out heated air drying again;
8) rolling is carried out to film, make PE film.
Preferably, the film after described primary coat carries out hot air dries and adopts hot air temperature to be 70-80 DEG C, and drying time is 40-50 second.
Preferably, described is coated with and dries that technological temperature is 80-100 DEG C, drying time is 40-50 second.
The beneficial effect of above technical scheme is adopted to be: a kind of high-barrier PE membrane compound technology of the present invention intercepts liquid by being coated with polyvinylidene chloride (PVDC) latex to PE black and white Double-color film bottom, intercepts, reach and prevent film xanthochromia effect it; Be coated with acrylic acid and substitute polyurethane, efficiently solve in polyurethane coating, nitrogen element is to being coated with the catalyst poisoning phenomenon caused in silicone oil process; There is good barrier property, combination process is simple, chemical stability is high, the life-span is long, effectively avoid that mould release membrance turns yellow, good, the high problem solving catalyst poisoning in production of film-strength of temperature-resistance characteristic.
Detailed description of the invention
The following detailed description of the preferred embodiment of the present invention.
The specific embodiment of the present invention: a kind of PE membrane compound technology, is characterized in that, comprise the following steps:
1) masking liquid allotment, comprising: the agent of solvent-borne type acrylic adhesive and ethyl acetate are mixed with the ratio of 1:3 volume ratio, then PVDC emulsion and water is mixed with the ratio of 1:1 volume ratio, then both is mixed;
2) film raw material is unreeled with permanent pulling force;
3) sided corona treatment is carried out to the film after unreeling;
4) film after sided corona treatment is carried out primary coat by metal chromium plating anilox roll;
5) masking liquid is applied to film bottom surface, completes primary coat operation, hot air dries is carried out to film;
6) after completing drying, masking liquid is applied to film bottom surface, finished surface is coated with operation;
7) facial mask is carried out heated air drying again;
8) rolling is carried out to film, make PE film.
Film after primary coat carries out hot air dries and adopts hot air temperature to be 70-80 DEG C, and drying time is 40-50 second; Face painting oven dry technological temperature is 80-100 DEG C, drying time is 40-50 second.
A kind of PE membrane compound technology of the present invention intercepts liquid by being coated with polyvinylidene chloride (PVDC) latex to PE black and white Double-color film bottom, intercepts, reach and prevent film xanthochromia effect it; Be coated with acrylic acid and substitute polyurethane, efficiently solve in polyurethane coating, nitrogen element is to being coated with the catalyst poisoning phenomenon caused in silicone oil process; There is good barrier property, combination process is simple, chemical stability is high, the life-span is long, effectively avoid that mould release membrance turns yellow, good, the high problem solving catalyst poisoning in production of film-strength of temperature-resistance characteristic.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
