Description
Technical Field
The invention belongs to the technical field of spinning, and particularly relates to a composite device for a flame-retardant waterproof coating of a fabric.
Background
The fabric coating process is a production and processing method of functional fabric, the fabric can have barrier function through the coating, including waterproof, windproof, various biochemical toxicants preventing, flame retardant and other effects, so the fabric is deeply favored by the broad masses of users and forms a large class of textile products. The coating method can be divided into a wet coating method and a dry coating method, wherein the wet coating method is also called as a coagulating bath coating method, namely coating glue is applied to the surface of a fabric substrate and directly enters a coagulating bath, the coating glue is coagulated into a film in the coagulating bath through the exchange of a solvent and a non-solvent, and then the film is dried and treated. Dry coating is a method of directly coating a coating adhesive on the surface of a fabric substrate by blade coating, and volatilizing a solvent to form a film by high-temperature drying, and is usually used for preparing a non-porous film (or a closed-pore film). Dry coatings are sought by enterprises because of low cost and simple process.
Coating equipment is generally designed to meet the requirements of the production process and to provide the fabric with the required functions, and researchers have studied different process technologies for achieving coated fabrics with different effects, thereby developing and designing coating equipment with different processing principles and methods. For the flame-retardant waterproof coating of the fabric, the waterproof performance of the fabric is required to be realized, the high water pressure resistance value of the coated fabric is ensured, and the good flame-retardant performance of the fabric is ensured. In the method for realizing the flame-retardant effect of the coated fabric, a flame-retardant fiber fabric coating mode can be adopted, or the fabric is directly subjected to flame-retardant glue coating. Because the combination of the flame-retardant fiber fabric and the non-flame-retardant coating can generate a wick effect and can not achieve good flame-retardant effect, a flame-retardant component still needs to be added into the coating glue, which greatly increases the cost of the fabric. Therefore, the flame retardant function of the fabric is usually achieved by applying a flame retardant functional coating to a common non-flame retardant fabric. For this method, the performance of the flame retardant in the coating adhesive and the coating process become important factors affecting the flame retardant efficacy of the fabric. The flame retardant in the coating adhesive has a plurality of varieties, and related documents of the existing flame-retardant coating adhesive show that the inorganic flame retardant is the first choice due to high-efficiency flame retardance, but the toughness of the flame-retardant coating adhesive can be influenced due to the addition of the inorganic flame retardant into the coating adhesive, and particularly, the toughness of the coating adhesive at low temperature is controlled, so that the control of the quantity of the flame retardant becomes one of key factors. In addition, from the mechanism of the coating for realizing the flame retardance of the fabric, the combination mode and the combination degree of the flame-retardant coating glue and the fabric directly influence the flame-retardant efficacy of the fabric, particularly the bottom coating layer which is in contact with the fabric, and the amount of the coating glue which directly penetrates into the fabric and the total amount of the bottom coating glue are also key factors influencing the flame-retardant efficacy of the fabric. How to realize good combination of the bottom surface coating glue and the fabric, the corresponding coating process and equipment are the key points of research.
The waterproof function of the fabric can be obtained by adopting a coating or film covering mode, the film covering mode usually adopts a polymer compact film to be attached to the fabric through a resin adhesive bonding mode, so that the excellent waterproof function is obtained, but the flame retardant effect on the fabric cannot be realized due to the film covering mode being the mode of being attached to the fabric. The original effect of coating the fabric with the coating adhesive is to obtain a waterproof function, but the addition of the inorganic flame retardant in the flame-retardant coating adhesive (which is equivalent to the addition of the inorganic particles in the coating adhesive) reduces the water pressure resistance value of the coating adhesive, and in order to improve the waterproof effect of the flame-retardant coated fabric, the coating times of the coating adhesive (generally 3 coatings of primer, medium adhesive and surface adhesive) are increased to achieve the waterproof effect of the coated fabric. Because the existing coating equipment adopts a scraper type coating mode, the control precision is lower, and the coating glue quantity is larger. The mode of combining the coating and the film covering is an effective means for realizing the flame retardant and waterproof effects of the coated fabric, but at present, no related one-step coating compounding equipment exists.
