Heatproof spraying-free high-gloss nylon material and preparation method thereof

Abstract

The invention relates to the field of automobile material preparation, and especially relates to a heatproof spraying-free high-gloss nylon material and a preparation method thereof. The nylon material is composed of following raw materials in parts by weight: 55.9 to 82.8 parts of semi-aromatic nylon resin, 5 to 20 parts of polycaprolactam and / or poly(nylon 66), 10 to 20 parts of solid glass bead, 1 to 3 parts of brightener, 0.4 to 0.8 part of antioxidant, 0.5 to 1.5 parts of coloring agent, and 0.3 to 0.8 part of lubricant. The provided nylon material is mainly made of semi-aromatic nylon resin; the matrix is in a highly transparent glass state; compared with other automobile spraying-free black decorative materials, such as PMMA, ABS, and the like, and the provided nylon material has abetter dyeing performance and a better temperature tolerant property, is capable of forming a highly bright and black coating, and is resistant to scratching, chemical products, and impact. The provided nylon material does not need any complicated spraying technology, the cost is reduced, and moreover, the nylon material is healthy and environmentally friendly and has an important practical value.

Description

technical field [0001] The invention relates to the field of automobile and material preparation, in particular to a heat-resistant spray-free high-gloss nylon material and a preparation method thereof. Background technique [0002] With the continuous promotion of the concept of automobile lightweight, the proportion of plastic products in auto parts continues to expand, and the interior and exterior parts of automobiles are basically made of plastic. In order to achieve a high decorative effect with the same color or different color as the body, it is generally necessary to spray a layer of paint film on the plastic parts. The typical coating process of plastic parts includes pretreatment (oil removal, release agent removal, cleaning, etc.), primer spraying, color paint spraying, varnish spraying (2K varnish), drying, topcoat modification and inspection, etc. The process route is complicated, and the coating process needs to be changed according to the different character...

AI Technical Summary

Problems solved by technology

[0003] At present, ABS, PC / ABS, and PMMA / ABS are the main paint-free black decorative materials for automobiles. Compared with traditional spray-painted materials, spray-free materials have shortcomings in appearance, temperature resistance, scratch resistance, chemical resistance, and impact resistance.
