Problems solved by technology

The water-based paints of this paint are incompatible with each other, so that the multi-color paint can be completed by a single spraying, and the construction is fast and convenient. However, the HJ / T 201-2005 "Technical Requirements for Environmental Labeling Products Water-based Paint" standard stipulates in the patent that it cannot be used. Glycol ether substances (film-forming aids), so it is not a green and environmentally friendly coating product

Abstract

The invention belongs to the field of paint, in particular to a full-aqueous multicolour paint comprising the following components in parts by weight: 35-40 parts of acrylate emulsion, 0.4-0.7 part of film-forming additive, 6-15 parts of water, 50-60 parts of colorful particle and a proper quantity of thickening agent. The paint of the invention has the characteristic of low VOC and does not contain banned substance ruled in the HJ / T 201-2005 technical requirement for environment labelling product-water-soluble coatings; meanwhile, the inventor especially researches the paint formula according to impact on granulation by pigment filler, and thus the pigment filler has reasonable ingredient; the prepared full-aqueous multicolour paint has the advantages of environment protection, stable quality, controllable colorful particle granulation and the like and solves the defects that the colorful paint contains ingredients harmful on human body and the colorful particle is easy to bleed. The invention also provides the preparation method of the above paint.

Description

technical field [0001] The invention belongs to the field of paint compositions, and relates to a paint, in particular to an all-water-based colorful paint and a preparation method thereof. Background technique [0002] Colorful paint is widely used in decoration engineering because of its rich colors, convenient construction, strong three-dimensional decorative effect, low price, and convenient renovation and renewal after one spraying. Colorful paints are different from traditional architectural paints, such as acrylic paints, styrene-acrylic paints, etc. These paints are single-phase, single-color uniform paint products, and the product quality is relatively stable, while colorful paints are multi-color, multi-phase particles mixed Coexistence, the stability of product quality may have many problems. [0003] At present, the fully water-based colorful interior and exterior wall coatings disclosed by domestic and foreign patents have mostly small and chaotic patterns and ...
