Problems solved by technology

[0005] Aiming at the problems in the prior art that the near-infrared reflection efficiency of the helmet coating is not high and the heat dissipation performance is poor, resulting in poor comfort for the wearer, the first purpose of the present application is to provide a cooling composite coating for the helmet. The cooling composite coating for helmets is compounded and modified by selecting nano far-infrared powder and infrared high-reflective black pigment as the main materials, using infrared high-reflective black pigment to improve heat reflection efficiency, and nano-far-infrared powder to improve heat dissipation. The person cooperates to reduce the temperature of the outer layer of the helmet and the inner layer of the helmet, so that the wearer has a good experience; the second purpose of the application is to provide a method for preparing a cooling composite coating for a helmet, and the steps of the preparation method Simple, easy to operate, through the air spraying scheme, it can quickly coat and generate a composite coating, and at the same time, the bonding degree between the coating and the coating is high, thereby improving the efficiency of production preparation and reducing the cost of coating production

Abstract

The invention relates to the field of coatings, and particularly discloses a cooling composite coating for a helmet and a preparation method thereof. The cooling composite coating for the helmet comprises a thermal radiation cooling layer and a near-infrared reflecting layer which are sequentially coated from inside to outside. The preparation method comprises the following steps: preparing thermal radiation cooling primer, preparing near-infrared reflecting paint and preparing the cooling composite coating for the helmet. The cooling composite coating for the helmet can be used for the surface of the helmet; the coating improves the heat reflection efficiency through the infrared high-reflection black pigment, the heat dissipation strength is improved through the nanometer far infrared powder, the temperature of the helmet outer layer and the temperature of the helmet inner layer are reduced through cooperation of the infrared high-reflection black pigment and the nanometer far infrared powder, and therefore a wearer has good use experience. Besides, in the preparation method, through an air spraying scheme, the composite coating is rapidly coated and generated, and the preparation method has the advantages of being high in production efficiency and low in production cost.

Description

technical field [0001] The application relates to the field of coatings, more specifically, it relates to a cooling composite coating for helmets and a preparation method thereof. Background technique [0002] The helmet is a relatively common and important protective equipment in modern traffic. Its main purpose is to protect the head of the driver and passengers when they are impacted, buffer the collision process, prolong the collision time, reduce the energy transmitted to the brain, prevent or reduce injuries and even save lives. [0003] In modern transportation, helmets are used more and more frequently, and their use and comfort are also key factors for existing consumers to consider. However, most of the PE coatings currently applied to helmets do not cool down , Anti-contamination effect, so only through the structure or coating of the helmet itself, it cannot achieve effective cooling effect at all. [0004] For example, Chinese Patent No. CN109897491A discloses...
