Problems solved by technology

This invention adjusts the paint film formula only from the paint itself, but does not consider the influence of construction environment and other influencing factors on the paint film gloss
[0004] At present, in the northern region, the process conditions used in the spraying process of water-based epoxy topcoat are generally paint viscosity of 95s, flash-off time of 1h, baking at 60°C for 2h, and the average glossiness of the paint film of water-based topcoat is 16 / 60° , due to the ambient temperature below 15°C and humidity between 15% and 30% in winter in the north, the environmental conditions are dry and cold. Adjustment from the paint itself alone has a large deviation from the designed gloss, which cannot fully meet the customer's requirements for gloss. Stability requirements, the traditional process of general water-based topcoat is no longer applicable

Abstract

The invention particularly relates to a method for finely adjusting the glossiness of a water-based matte finish paint by improving a spraying process, and belongs to the technical field of water-based coating spraying construction. The technical problem to be solved is paint film glossiness deviation caused by construction factors. The method for finely adjusting the glossiness of the water-basedmatte finish paint by improving the spraying process comprises the following process conditions: (1) the paint viscosity of the water-based epoxy finish paint spraying process is improved to be 20-23s; 2) the flash-drying time of the water-based epoxy finish paint is canceled, and 3) the finish paint is baked at 45-53 DEG C for 2-2.5 h. The problem of paint film glossiness deviation caused by construction factors is effectively solved by investigating the factors such as the drying mode, the flash-drying time and the paint viscosity, and the one-time delivery qualification rate of products is improved.

Description

technical field [0001] The invention belongs to the technical field of water-based paint spraying construction, and in particular relates to a method for finely adjusting the glossiness of a water-based matte finish paint by improving the spraying process. Background technique [0002] Paint film gloss, also known as specular gloss, refers to the ability of paint film to reflect light and is an important indicator of decorative coatings. Due to the advantages of water-based paint in terms of environmental protection and energy conservation, its output has increased year by year in recent years, and users have higher and higher requirements for the decorative performance of water-based paint. Water-based coatings are divided into bright water-based coatings, semi-matte water-based coatings and matte water-based coatings according to the gloss, and their applications are different. Glossy coatings are generally used outdoors, which can give people a full and bright color expe...
