Abstract

The invention relates to the field of coatings, and particularly discloses a heat insulation and heat preservation type reflective coating for a helmet and a preparation method of the heat insulation and heat preservation type reflective coating. The heat insulation and heat preservation type reflective coating for the helmet comprises the following substances in parts by weight: 80-100 parts of matrix emulsion, 6-8 parts of a heat preservation type reflective material, 1-3 parts of polyvinyl alcohol, 3-5 parts of a functional additive, 25-40 parts of water and 1-2 parts of composite filler, the heat preservation type reflective material is hollow glass microsphere particles, the particle size of the hollow glass microsphere particles is 20-150 microns, and the refractive index of the hollow glass microsphere particles is 1.8-2.0. The preparation method comprises the following steps: S1, premixing; s2, performing secondary mixing; and S3, uniformly mixing. The formula of the heat insulation and heat preservation type reflective coating for the helmet is optimized, transmission between external temperature and internal temperature is effectively isolated through the hollow structure of the hollow glass microspheres, and the heat insulation and heat preservation performance of the reflective coating for the helmet is improved.

Description

technical field [0001] The present application relates to the field of coatings, in particular to a heat-insulating and heat-preserving reflective coating for helmets and a preparation method thereof. Background technique [0002] As a kind of safety protection, helmet is widely used in all walks of life. In order to improve the competitiveness of products, it is not only required that the helmet has safety protection performance in line with international standards, but also requires the helmet to have excellent appearance and outdoor durability. At the same time, in actual use, helmets are used as safety protection products matched with motorcycles and off-road vehicles, and generally use coatings with similar performance and appearance to automobile coatings to meet the needs of users in different environments and conditions. [0003] In daily life, the absorption and reflection of light can change the color of objects, depending on the angle of light and the angle of hu...
