Problems solved by technology

At present, there are few adhesives specially used for wall coverings. Commonly used wall covering adhesives include powdered adhesives, such as starch and its derivatives, cellulose and its derivatives. These adhesives are environmentally friendly, non-toxic, tasteless, and reversible. Non-toxic, instant and other advantages, but there is a big lack in mildew resistance and water resistance; the other is water-based adhesives, this type of adhesive has the advantages of strong adaptability, not easy to fall off, and will not pollute the wall covering, but the disadvantages It is necessary to add water for reconciliation during use, and air bubbles are likely to be generated during the reconciliation process, which will affect the bonding effect in severe cases
[0003] CN107488419A discloses an adhesive for pasting wallpaper and wall coverings, comprising the following components by weight percentage: 20-30% of PVA glue with a concentration of 10%, 8-15% of potato modified starch, 0.2-0.8% of acrylic acid emulsion, disinfectant Foaming agent 0.02-0.1%, moisturizing agent 0.05-0.25%, wetting agent 0.05-0.25%, preservative 0.1-0.3%, PH regulator 0.1-0.5%, and the balance is water. The adhesive prepared by the invention is used to bond wallpaper The effect is better, but it is easy to fall off when bonding the wall covering, the film forming time is longer, and there is a phenomenon that it is easy to degumming after a long time of use

Abstract

The invention provides a wall cloth glutinous adhesive powder. The wall cloth glutinous adhesive powder is prepared from the following raw materials in parts by weight: 90 to 110 parts of waxy corn starch, 2.5 to 5 parts of an ionic alkali, 0.1 to 0.2 part of a cross-linking agent, 1 to 5 parts of an oxidant, 30 to 40 parts of sodium polyacrylate, 5 to 15 parts of polyvinylamine, 0.01 to 0.05 partof a mildew preventive and 60 to 80 parts of water. The wall cloth glutinous adhesive powder has the advantages of high viscosity, proper initial viscosity, good freeze-thaw property, fluidity and waterproofness, and is convenient for glue applying and wall cloth moving and adjusting.

Description

technical field [0001] The invention belongs to the field of architectural decoration, and in particular relates to a waxy rubber powder for wall coverings and a preparation method and application thereof. Background technique [0002] In interior decoration, adhesives are needed to paste wall coverings. Due to the particularity of wall coverings, the general requirement for adhesives is that they have greater polarity, better bonding, heat resistance, water resistance, and alkali resistance. 1. Anti-mildew is the basic requirement for wall covering adhesives. At present, there are few adhesives specially used for wall coverings. Commonly used wall covering adhesives include powdered adhesives, such as starch and its derivatives, cellulose and its derivatives. These adhesives are environmentally friendly, non-toxic, tasteless, and reversible. Non-toxic, instant and other advantages, but there is a big lack in mildew resistance and water resistance; the other is water-based ...
