Embodiment 1

[0035] The orange-peel-like structure polymer coating described in this embodiment is prepared from a polymer matrix, a foaming aid, and an oily substance. Wherein, the polymer matrix is ​​polyurethane, and in this embodiment, the polyurethane is prepared from polyurethane TDI prepolymer and polyol. The foaming aid is water, in this embodiment, it is deionized water. The oily substance is formed by mixing liquid paraffin and safflower oil in a weight ratio of 1:1.

[0036] The preparation method of class orange peel structure polymer coating described in the present embodiment is specifically as follows:

[0037] Mix and stir 100 parts of polyurethane TDI prepolymer A component, 83 parts of polyol B component, 2 parts of foaming aid, and 28 parts of oily substance, and then drop-coat it on a clean glass plate to form a film , the thickness of the film layer is about 0.75mm, and it is cured at 20°C for 24h.

Abstract

The invention provides a polymer coating with an orange peel like structure. The polymer coating comprises a surface layer, a sponge layer, and a liquid capsule. The surface layer is covered on the surface of the sponge layer. The liquid capsule is arranged in the sponge layer. An oily substance is filled in the liquid capsule. The invention also provides a preparation method of the polymer coating with an orange peel like structure. The oily substance, which is not compatible with the surface layer and the sponge layer, is stored in the liquid capsule; the loss of the oily substance is greatly reduced; the coating can be stably and continuously used, the durability of the coating is good, and in a long term, the coating has a good anti-freeze and anti-fouling effect.

Description

technical field [0001] The invention belongs to the technical field of coating materials, and in particular relates to a polymer coating with an orange peel structure and a preparation method thereof. Background technique [0002] Common citrus peels in daily life are composed of hard epidermis, white sponge layer and tiny oil sacs. When subjected to a certain squeezing force, the sponge layer pushes outward, forming tiny cracks in the epidermis, and sprays out phytotoxic and Antibacterial fragrance oil to protect against predators and bacterial infections. In 2018, Nicholas M et al. studied the micro-jet phenomenon when the orange peel composite layered structure was subjected to twisting force, which inspired potential applications such as drug atomization and bridge self-diagnosis. [0003] In 2014, Wong TS et al., inspired by the predation effect of Nepenthes, locked the lubricating liquid in the porous texture of the micro-nanostructured surface, and constructed a supe...
