At present, the construction method of micro-airbag materials is generally one or two paving constructions. Because its structure is microporous, it is not suitable for direct contact with the surface layer. Before spraying the surface layer, it is necessary to construct a dense all-plastic layer on the foam layer. layer, the construction process is troublesome

Abstract
The invention belongs to the technical field of plastic materials and particularly relates to a plastic self-skinning micro-balloon material and a preparation method thereof. The plastic self-skinningmicro-balloon material comprises, by weight, 45 to 53% of polyether polyol, 30 to 33% of isocyanate, 0.6 to 1% of a catalyst, 1 to 2% of silicone oil, 10 to 14% of a filler, 3 to 5% of a pigment, 0.5to 1% of an antioxidant, 0.5 to 1% of an ultraviolet absorber and 0.5 to 1% of a wetting agent. The preparation method is easy to construct, has long construction time and is easy to operate and implement. After one implementing process, the bottom has a foaming layer with excellent elasticity and provides excellent resilience and comfort for the place. The upper part comprises a compact reinforcing layer material. After construction, the micro-balloon layer can be directly sprayed to the surface layer so that the bonding strength between the surface layer and the bottom layer is guaranteed and the process of constructing the reinforcing layer is avoided.
Description
technical field [0001] The invention belongs to the technical field of plastic materials, and in particular relates to a plastic self-skinning micro-airbag material and a preparation method thereof. Background technique [0002] The plastic runway has been favored by everyone since its birth due to its bright and beautiful colors, suitable hardness, excellent strength, and easy maintenance. Micro-airbag materials have been favored by everyone in recent years for their moderate elasticity, high comfort, and excellent physical properties. At present, the construction method of micro-airbag materials is generally one or two paving constructions. Because its structure is microporous, it is not suitable for direct contact with the surface layer. Before spraying the surface layer, it is necessary to construct a dense all-plastic layer on the foam layer. layer, the construction process is troublesome.
