Embodiment 1

[0013] A kind of alcohol substitute glue, take 45kg British imported montmorillonite inorganic gel Laponite, 4.5kg sodium bentonite, 33kg hydroxypropyl methylcellulose HPMC, 11kg acrylamide and 4.5kg cornstarch into a dry powder mixer, stir In 25-30 minutes, the alcohol-based glue of the present invention is obtained.

[0014] When the present invention is used, to make the putty for interior and exterior walls, add 120 kilograms of water per kilogram of the alcohol-based rubber powder of the present invention, and only need to use 5 to 6 kilograms per ton for the putty for interior and exterior walls.

Embodiment 2

[0016] A kind of alcohol substitute glue, put 50kg montmorillonite inorganic gel Magnabrite, 5kg sodium bentonite, 35kg hydroxypropyl methylcellulose HPMC, 10kg acrylamide and 5kg corn starch into a dry powder mixer, stir for 25-30 minutes Obtain alcohol substitute glue of the present invention.

[0017] When the present invention is used, add 120 kilograms of water per kilogram of the alcohol substitute rubber powder of the present invention, and only need to add 2 to 3 kilograms per ton of mortar.

Abstract

The invention provides an alcohol-substituting glue which comprises the following components by weight percent: 40%-50% of montmorillonite inorganic gel, 4%-5% of sodium bentonite, 30%-35% of hydroxypropyl methyl cellulose (HPMC), 10%-12% of acrylamide and 4%-5% of corn starch; and the montmorillonite inorganic gel is Laponite or Magnabrite imported from Great Britain. The alcohol-substituting glue can substitute traditional polyvinyl alcohol, be quickly dissolved in cold water and be convenient for use; the alcohol-substituting glue has excellent film forming property, water retention property, thickening property, effect of keeping flat and dispersibility, and is green and environment-friendly; and 120kg of water needs to be added in each kg of the alcohol-substituting glue, when being used as a putty for interior and external walls or a toughened coating, each ton only needs 5-6kg, when being used as mortar, each ton only needs 2-3kg, and the alcohol-substituting glue can be widelyapplied in the fields of building mortar, putty, chemical building materials and the like.

Description

technical field [0001] The invention relates to a chemical building material, in particular to an alcohol substitute glue. Background technique [0002] The traditional building material polyvinyl alcohol needs to be heated and boiled, and formaldehyde must be added to condense, the reaction is harmful to the human body, and the residual formaldehyde is also the culprit of indoor pollution; and its film-forming, water-retaining, thickening properties are not very good ideal. Contents of the invention [0003] The present invention overcomes the deficiencies of the prior art, and provides a substitute alcohol glue, which replaces the traditional polyvinyl alcohol, can be quickly dissolved in cold water, and has good film-forming, water-retaining, thickening, leveling and dispersing properties. Excellent and green. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A substitute alcohol glue, comprising by ...
