A high-coverage, wash-resistant, one-pass waterborne interior paint

Abstract

The invention relates to a water-based interior wall paint with high covering and washing resistance in one application, and the water-based interior wall paint in one application with high covering and washing resistance comprises hydroxyethyl cellulose, hydrophobically modified hydroxyethyl cellulose, rheological Additives, alkali swelling thickener, tert-acetic acid emulsion, alcohol ester twelve, silicone additives and water. The water-based interior wall paint with high coverage and washability disclosed by the present invention has excellent storage and transportation properties; it can endow the paint film with excellent fullness and leveling; and the product of the present invention has very excellent hiding power , Scrub resistance and film-forming properties, the contrast ratio exceeds 0.99, the scrub resistance exceeds 20,000 times, the low-temperature film formation of 750μm wet film has no cracking, and the paint film with one-time application has the characteristics of excellent covering, rub resistance and no cracking; The product of the invention is easy to apply, has low manufacturing cost, is easily accepted by ordinary consumers, and has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of architectural coatings, in particular to a water-based interior wall paint with high covering and scrubbing resistance. Background technique [0002] Water-based interior wall paint has the characteristics of easy application, excellent performance, non-toxic and environmental protection, and occupies a dominant position in the domestic interior wall decoration field, with a market share of at least 70%. For ordinary water-based interior wall paint to achieve better results, the application process is one base and two sides, which needs to be applied three times. However, the labor cost is getting higher and higher now, and applying three times will also prolong the occupancy time of the owner. Although there are products on the market that apply water-based interior wall paint once, there are generally four major defects in it: the first 1. The hiding power is poor. The general contrast ratio of the exi...

Problems solved by technology

However, the labor cost is getting higher and higher now, and applying three times will also prolong the occupancy time of the owner. Although there are products on the market that apply water-based interior wall paint once, there are generally four major defects in it: the first 1. The hiding power is poor. The general contrast ratio of the existing one-step application technology products only reaches 0.95 required by the high-quality products in the GB / T9756 standard, and it is difficult to increase the contrast ratio. It is more likely to have the problems of penetration and poor coverage in application; second, the washing resistance is poor. Compared with the water-based interior wall paint of the ordinary three-pass application process, the product with one-pass application of the current technology has paint film deviation after application. Thin, insufficient fullness, and poor wear resistance; third, thick coating is easy to crack, in order to achieve sufficient fullness of the paint film applied in one pass, the current technical products have the phenomenon of roller coating cracking, especially It is especially obvious when thick coating; Fourth, the cost is expensive. In order to achieve high hiding power and high scrub resistance, more titanium dioxide and emulsion are generally used, which leads to high manufacturing costs and is not popular with ordinary consumers.
