Abstract

The invention discloses a process for manufacturing a PP (polypropylene) water-resistant and breathable film. The process comprises the following steps: mixing 4 mass parts of PP, 5 mass parts of calcium carbonate powder and 0.5 mass part of coupling agent in an extruder; heating to 230-260 DEG C; mixing and extruding to cool and form a thin film of which the thickness is 60 microns; stretching the formed film in a single direction to enable the length to be tripled. The PP and the calcium carbonate powder are mixed to form the thin film under the action of the coupling agent; after the thin film is prepared, the PP material is stretched in the single direction; the calcium carbonate powder does not have the extension performance, so that micro holes can be formed in the surface of the thin film after stretching; the aperture of the micro holes is in a nano level generally, only water vapor molecules can pass through the micro holes, and liquid water molecules cannot pass through the micro holes, so that excellent water resistance and breathability can be achieved.

Description

A kind of PP waterproof ventilated membrane processing technology
Technical field
The present invention relates to casting films simple tension production technical field, specifically a kind of PP waterproof ventilated membrane processing technology.
Background technology
For present building, most of bodies of wall are all adopt pea gravel concreten or smear waterproof material to body of wall.So just there is following some deficiency: the thermal convection current of body of wall is accelerated, and is unfavorable for building heat preservation, causes energy loss; Extraneous rain water and steam causes and corrodes and go mouldy building wall.
Summary of the invention
The present invention is directed to prior art deficiency; a kind of PP waterproof ventilated membrane processing technology is provided; adopt the PP waterproof ventilated membrane that this processing technology is made to there is remarkable water-proof breathable properties; there is tight covered effect; the bedroom that protection building is not subject to steam and rainwater, keeps lasting usability and the heat insulation effect built.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of PP waterproof ventilated membrane processing technology, press mass fraction by 4 parts of polypropylene, 5 parts of calcium carbonate powders, 0.5 part of coupling agent is blended in and in extruder, is heated to 230-260 DEG C, mixing, extruding rear cooling and shaping, to become thickness be the film of 60 microns, then by 3 times of length of film simple tension of sizing.Mix with calcium carbonate powder by polypropylene, make it be mixed and made into film by the effect of coupling agent, polypropylene material is stretched making after film by simple tension, because calcium carbonate powder does not have extension property, after stretching, film surface can form micropore, and the aperture of this micropore is generally at Nano grade, and only water vapour molecule can pass through, liquid hydrone cannot pass through, and can realize remarkable water-proof breathable properties.
The present invention compared with prior art, there is following beneficial effect: the present invention mixes with calcium carbonate powder by polypropylene, make it be mixed and made into film by the effect of coupling agent, polypropylene material is stretched making after film by simple tension, because calcium carbonate powder does not have extension property, after stretching, film surface can form micropore, the aperture of this micropore is generally at Nano grade, only water vapour molecule can pass through, liquid hydrone cannot pass through, and can realize remarkable water-proof breathable properties.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail: a kind of PP waterproof ventilated membrane processing technology, press mass fraction by 4 parts of polypropylene, 5 parts of calcium carbonate powders, 0.5 part of coupling agent is blended in and in extruder, is heated to 230-260 DEG C, mixing, extruding rear cooling and shaping, to become thickness be the film of 60 microns, then by 3 times of length of film simple tension of sizing.Mix with calcium carbonate powder by polypropylene, make it be mixed and made into film by the effect of coupling agent, polypropylene material is stretched making after film by simple tension, because calcium carbonate powder does not have extension property, after stretching, film surface can form micropore, and the aperture of this micropore is generally at Nano grade, and only water vapour molecule can pass through, liquid hydrone cannot pass through, and can realize remarkable water-proof breathable properties.
