Nanometer cellulose functional doped modified paint and preparation method thereof

Abstract

The invention discloses nanometer cellulose functional doped modified paint and a preparation method thereof. According to the nanometer cellulose functional doped modified paint and the preparation method thereof, the nanometer cellulose functional doped modified paint with one-dimensional nanometer dimensions (5-100 nm) is adopted for forming a compound system composed of a soft resin macromolecular chain structure and a hard nanometer cellulose structure with an ultra-high length-diameter ratio, surface functionalization of nanometer cellulose, a principle of the nanometer cellulose of interface structure toughening and the advantage that the one-dimensional nanometer cellulose and a macromolecular chain form a cross net are used, the tenacity, the impact resistance, the hardness and the surface strength of a paint surface layer are greatly improved, and the defects of cracks, chaps and the like, of a pant surface, caused by high or low temperature in a use process of the paint subjected to curing are overcome. The preparation method of the nanometer cellulose functional doped modified paint can be suitable for water-based paint or oil paint, and a paint product which is modified and prepared through a technology has excellent tenacity, hardness and surface strength, is low in cost, and can be applied in the field of multiple materials of woodware, metal, automobiles, plastic, glass, building surfaces and the like on a large scale.

Description

technical field [0001] The patent of the present invention relates to the manufacturing field of high-performance coatings, in particular to a nano-scale cellulose functional doped modified coating and its preparation method. The coating product can be used in interior decoration, automobiles, construction tooling, wood, metal, plastic, Large-scale application in various material fields such as glass and building surfaces. Background technique [0002] Indoor coatings are mainly divided into water-based coatings and solvent-based coatings, which are widely used in various fields such as construction, automobiles, ships, and aviation, and have a huge market capacity. At present, most architectural coatings have coating cracking phenomenon after long-term application. The main reason is that the cement base material of the building wall leaves surface cracks, pores and other defects during construction, and these defects will cause cracks in the paint attached to the surface,...

AI Technical Summary

Problems solved by technology

The main reason is that the cement base material of the building wall leaves surface cracks, pores and other defects during construction, and these defects will cause cracks in the paint attached to the surface, which not only affects the appearance, but also causes house leakage

At present, the more effective method is to use epoxy resin to repair cracks or use other paints to repair, but it causes a secondary process and cannot fundamentally solve the quality problem of the paint.
