Description
Technical Field
The invention relates to a hot-melt reactive polyurethane coating adhesive and a waterproof and moisture-permeable fabric, belonging to the technical field of textile processing.
Background
The waterproof performance of the textile refers to the capability of preventing rainwater and snow water in the external environment from permeating into the textile from the outside; the moisture permeability of textiles means that the fabric has the ability to diffuse perspiration from the human body through the fabric in the form of water vapor to the surrounding environment. The waterproof and moisture-permeable performance of the textile means that external rainwater and snow water cannot permeate into the textile, and internal sweat can permeate through the textile to be rapidly transmitted and evaporated to the outside, so that microclimate between a human body and clothes is adjusted, and a wearer is kept dry and warm.
The polyurethane has unique flexibility, wear resistance, bacterial resistance and good texture and is widely applied to the preparation of medium-high-end fabrics. The waterproof moisture-permeable coating adhesive for the textile at present is mainly of polyurethane, and is divided into solvent polyurethane and water-based polyurethane. The solvent type polyurethane waterproof moisture permeable coating adhesive uses an organic solvent, and most of the organic solvent has toxicity and produces pollution; the water-based polyurethane waterproof moisture-permeable coating adhesive needs a large amount of energy for drying and moisture volatilization in the production and use processes, the waterproof and moisture-permeable performances are not ideal enough, and a hot-melt coating adhesive without moisture permeability is also available on the market at present.
Therefore, a hot-melt reactive polyurethane coating adhesive and a waterproof moisture-permeable fabric are necessary.

The invention is realized by the following technical scheme:
a hot-melt reactive polyurethane coating adhesive comprises the following raw materials in parts by weight: 80-90% of TPU particles, 7-17% of crystalline end NCO polyurethane prepolymer and 3% of auxiliary agent.
In the hot-melt reactive polyurethane coating adhesive, the crystalline NCO-terminated polyurethane prepolymer is a polymer of isocyanate and polyol (the terminal group is NCO); wherein the isocyanate is one or more of TDI (toluene diisocyanate), MDI (ditolyl methane diisocyanate), IPDI (isophorone diisocyanate) or PAPI (polymethylene polyphenyl isocyanate); the polyols are polycaprolactone polyols of different molecular weights.
The hot-melt reactive polyurethane coating adhesive comprises one or more of a heat stabilizer, an antioxidant, an ultraviolet absorber, a filler or an organic silicon anti-adhesive.
The hot-melt reactive polyurethane coating adhesive is characterized in that the filler is a mixture of calcium carbonate and titanium dioxide.
A production method of a waterproof and moisture permeable fabric comprises the steps of uniformly mixing TPU particles, a crystalline end NCO polyurethane prepolymer and an auxiliary agent by a screw at the temperature of 150-180 ℃, injecting the mixture into a hot melt adhesive scraper coater, coating the mixture onto the fabric, and curing the mixture in the environment.
The fabric is nylon.
A waterproof moisture permeable fabric produced by a production method of the waterproof moisture permeable fabric.
The invention achieves the following beneficial effects:
the hot-melt reactive polyurethane coating adhesive adopts the crystalline end NCO polyurethane prepolymer, when in use, NCO in the crystalline end NCO polyurethane prepolymer can slowly react with water in the air to generate carbon dioxide, a large number of micro bubbles can be formed in the coating layer, the aperture size is between the minimum diameter (100 mu m) of water drops and the diameter (0.0004 mu m) of water vapor, and the fabric can only allow water vapor molecules to pass through and prevent the water drops from penetrating, so that the fabric has a waterproof function and a good moisture permeability effect, and the hand feeling of the coating fabric can be soft.
