Abstract
The invention relates to a manufacturing method of a sliding face waterproof film and joint cloth of the film. The invention has a technical proposal that firstly a layer of PU paste is painted on release papers or clothes with different surfaces to form a first film; secondly the PU paste is painted again to form a sliding face waterproof film; thirdly the sliding face waterproof film is peeled off to get the sliding face waterproof film; or the PU paste is directly adhered to clothes on an adhering machine to form a changeable sliding face waterproof PU film adhering product. The manufacturing method of the PU film improves the unsmooth feeling of PU films, and various changeable colors enhance the diversity of PU film products.
Description
Technical field
The present invention relates to the manufacture method of a kind of slip surface waterproof membrane and applying cloth thereof, especially about the manufacture method of sliding surface waterproof PU film and its applying cloth.
Prior art
Polyurethane (polyurethane, PU) be a kind of common macromolecular material with excellent properties such as wear-resisting, heatproof, sealing, sound insulation, good processability, degradables, be widely used in the elastomeric material of various sponge products, shock-absorbing friction resistant in daily life, and the substitute of natural rubber.
The manufacture method of sliding surface waterproof PU film has blown film (Blown Film) method and release liners to change two kinds of subsides methods; Yet, on water-proof function, change color and product feel, all perform poor with the PU film that the blown film mode is made; Change to paste the PU film of manufactured with release liners, then have and to make smooth surface, can't reach high water resistance quality and the high problem of manufacturing cost.
The manufacture method of slip surface waterproof membrane applying cloth is by traditional wet PU thin film manufacturing method, the PU thickener is spread upon on the cloth kind, again thickener and water are carried out exchange reaction, form a hydrophilic coating material, but this mode only can be coated on the PU thickener on the flat fabric kind, and be not suitable for elastical cloth kind or looped fabric kind, make the kind of product be very restricted.
Therefore, the present invention is for solving above-mentioned puzzlement, proposes a kind of the first film that forms earlier in a substrate, forms a sliding surface waterproof PU film again, peels off then and obtains sliding surface waterproof PU film or form the manufacture method of the film adhered cloth of PU with a cloth pasting.
Summary of the invention
Main purpose of the present invention is the manufacture method that proposes a kind of sliding surface waterproofing membrane, and it is produced, and the PU film has surface smoothing, many, the polynary senses of touch of change color, waterproof effect is good and the effect of low cost of manufacture.
Another object of the present invention is the preparation method that proposes a kind of slip surface waterproof membrane, and it can improve the monistic shortcoming of sliding surface waterproof PU film product of blown film (Blown film) manufactured.
A further object of the present invention is the preparation method that proposes a kind of slip surface waterproof membrane, and it can improve release liners and change the problem that the sliding surface waterproof PU film that pastes the manufacture method manufacturing can't reach high waterproof quality.
Another purpose of the present invention is the manufacture method that proposes a kind of slip surface waterproof membrane applying cloth, and it can improve the problem that the wet-type PU film-forming method is only applicable to flat fabric.
For reaching above-mentioned purpose, the present invention will be coated in the substrate by the thickener that the allotment of PU resin forms lightly, through the baking oven high-temperature baking to film forming, be coated with the PU thickener once more, and after oven dry is finished, form one deck sliding surface waterproof PU film, sliding surface waterproof PU film and substrate can be peeled off afterwards and obtain a sliding surface waterproof PU film or a sliding surface waterproof PU film and a cloth pasting are formed the film adhered cloth of a sliding surface waterproof PU.
Compared with prior art, the present invention has the following advantages:
The present invention forms a first film earlier in a substrate, form a sliding surface waterproof PU film again, peel off then to obtain sliding surface waterproof PU film or make and produce that the PU film has surface smoothing, many, the polynary senses of touch of change color, waterproof effect is good and the characteristics of low cost of manufacture with manufacture method that a cloth pasting forms the film adhered cloth of PU; And since the manufacturing process of sliding surface waterproofing membrane applying cloth of the present invention in, can use knitting or the flat fabric kind as applying cloth, improve the shortcoming that prior art only can be used the flat fabric kind, make PU Waterproof Breathable product have more diversity.
