Description
Technical field
The present invention relates to Archtectural Coatings technical field, particularly relate to a kind of antibiotic paint production method, further relate to this
The antibiotic paint that the method for kind produces, further relates to the air-permeable anti-bacterial film containing this antibiotic paint.
Background technology
In house ventilating water proof layer in building industry, often use breathable films, be used for improving inside masonry
Life-span of heat-barrier material and the heat-proof quality of building own, additionally also used in the building of some wooden structures
Make moistureproof and waterproof material, mainly it be layered on inside ceiling or the heat-barrier material inside wall be rolled in inside and outside.Anti-
Water ventilated membrane is a kind of novel high polymer waterproof material, and technology requires more much higher than general waterproof material；
Waterproof ventilated membrane also has the functional characteristics not available for other waterproof materials simultaneously.Waterproof ventilated membrane is being strengthened
While building air-tightness, watertightness, inside configuration steam can be made to discharge rapidly, it is to avoid structure multiplies mycete,
Protection property value, is the new energy-saving material of a kind of health environment-friendly.
At present, the waterproof ventilated membrane of main flow by Polypropylene race, the saturating steam film of macromolecule, grid reinforcing rib and gathers
Propylene is composited by PUR.Owing to waterproof ventilated membrane will be at various harsh bars such as high temperature, ultraviolet radiation
Part, uses decades at building external, so the adhesion strength between each layer of waterproof ventilated membrane is particularly important.
Prior art generally use general EVOH resin bond, and the bond effect of general EVOH resin
Not being to make us feeling quite pleased resin, EVOH is poor to most polymers adhesive force, it is therefore desirable to it is special to design
Binder resin, improves the adhesion strength between each layer of waterproof ventilated membrane.
Such as Chinese Patent Application No. be 028205154 patent disclose a kind of based on amorphous poly-α-alkene
