Composite structure with anti-yellowing raw water-based resin layer

The present invention relates to a composite structure with an anti-yellowing raw water-based resin layer, especially a composite structure having the advantages of windproof, waterproof, breathable and anti-yellowing, and can further be used as a raw material or interlayer of related products according to requirements.

At present, there are many kinds of composite materials with polyurethane resin layers, and the raw materials and interlayers are selected by the industry to create a composite structure with special functions. Polyurethane (PU) refers to a class of polymers containing a characteristic unit of carbamate in the main chain. Polyurethane-based products are generally characterized by light weight, toughness, corrosion resistance, and abrasion resistance. Polyurethanes are often used in the daily life to make various foams and plastic sponges. In the synthesis of traditional solvent-based polyurethanes, a large amount of organic solvents are used, which not only poses a health hazard or harm to process personnel or even product users, but also emits a large amount of volatile organic compounds throughout the process. Compounds, carbon dioxide and toxic waste have a serious impact on the environment. Therefore, in recent years, water-based polyurethane (DPU) has gradually replaced solvent-based polyurethane, and has been widely used in various applications such as coating processing of leather, leather processing, adhesives, sealants, and plastic molding. However, water-based polyurethanes still have their shortcomings in application, such as poor thickening, poor water resistance and gloss of the film, high resilience of the film surface, and easy adhesion. Therefore, the related industry has also developed a better water-based polyurethane to overcome the above problems; for example, Chinese Patent Publication No. CN 103613921 discloses "an aqueous polyurethane", and the Republic of China Patent Publication No. I418583 discloses a "high-resistance water-repellent water-based polyurethane. The production method of the foamed film is proposed to have good water resistance and resistance. A water-repellent polyurethane foam film with high resistance and resilience to avoid the influence of mold adhesion on the operation of the machine and the lack of creases on the surface of the textile product.

Although the above research and development solves the problem that the traditional solvent-based polyurethane is harmful to the human body and the environment, most of the raw materials of the water-based polyurethane on the market are derived from non-renewable raw materials such as petroleum. In view of the current global shortage of oil, if we can get rid of the dependence on petroleum resources, the use of biomass materials as a material source will greatly reduce the oil consumption; however, there are still many defects in the raw waterborne polyurethane. For example, poor viscosity stability leads to poor subsequent foaming effect, and yellowing is likely to occur. The causes of yellowing mainly include high temperature, ultraviolet rays, nitrogen oxides (NOx) in the air, and the like. The phenomenon of yellowing is particularly troublesome for the use of white or light-colored cloth. Therefore, how to provide a better water-containing polyurethane composite structure to reduce the yellowing phenomenon and enhance the windproof, waterproof, and breathable ability of the composite structure has become the direction that the creator thinks.

The reason is that the creator has created a composite structure with an anti-yellowing raw water-based resin layer in view of the many designs and developments and actual production experience of the related industries in view of the many defects in the actual implementation of the existing composite structure. It is to provide a structure with windproof, waterproof, breathable and anti-yellowing functions, which can provide the raw materials or interlayers of related products according to the requirements; therefore, the creation has multiple functions.

In order to achieve the above-mentioned object, the present inventors propose a composite structure having an anti-yellowing raw water-based resin layer, comprising a lining substrate layer; a primary aqueous resin layer having a plurality of foaming holes and having a first surface And a second surface, wherein the first surface is fixedly attached to the lining substrate layer; and the one side of the substrate layer is fixedly attached to the second surface of the green resin layer.

In one embodiment of the present invention, the raw water-based resin layer is selected from the polyester polyol of the raw material; further, the raw water-based resin layer has a total weight of 100% of the composition. The ratio calculation includes 55% aqueous biopolymer polyurethane, 1~2% anti-adhesive agent, 1-2% foaming agent, 1-4% foam stabilizer, 3~7% bridging agent, 0.3~0.5%. Anti-yellowing agent, and the remaining weight percentage of solvent.

In one embodiment of the present invention, the raw water-based resin layer is sequentially obtained by a step of foaming, coating, pre-drying, pressing, and aging.

In one embodiment of the present invention, the lining substrate layer and the facing substrate layer are selected from any of cotton, polyester fiber, nylon, and enamel, or a blend of two or three of the fibers.

Therefore, the creation uses a composite structure made of environmentally-friendly materials, and has the ability of being windproof, waterproof, breathable, anti-yellowing, etc. The plurality of foaming holes provided by the raw water-based resin layer can provide a composite material with better flexibility and ventilation.
