Elastic putty and preparation method thereof

Abstract

The invention relates to elastic putty and a preparation method thereof. The elastic putty is made from the following raw materials in parts by weight: 20-25 parts of cement, 10-15 parts of fly ash or steel slag, 2-6 parts of white lime, 30-40 parts of calcium carbonate, 20-30 parts of quartz sand, 0.1-1 part of cellulose ether, 0.1-0.5 part of lignocellulose, 0.01-0.04 part of starch ether, 0.1-0.4 part of powdery water repellent and 4-15 parts of dispersible gelatine powder. The preparation method comprises the steps of adding all raw materials in a dispersion machine in proportion, and stirring the raw materials for 45 min to obtain the elastic putty. The elastic putty has good bonding strength with various materials, and has higher compressive strength, bending strength, tensile strength, permeability resistance and waterproof performance; the putty has flexibility after curing, strong protection properties, easy construction and good durability, is easy to foundry mill at early period while having high intensity at later period, is innoxious, flavourless and non-inflammable, and belongs to recycled product of industrial waste residues.

Description

technical field

[0001] The invention relates to a putty and a preparation method thereof, in particular to an elastic putty and a preparation method thereof, belonging to the technical field of building materials. Background technique

[0002] On the interior and exterior walls that have been coated with architectural paint, it is often found that the surface of the wall is rough, uneven, cracked, peeled and peeled off. Tortoise cracks cause water seepage on the back surface of the coating, which causes the coating to peel and fall off, and even affect the function and appearance of the building. Contents of the invention

[0003] The purpose of the present invention is to overcome the above-mentioned defects in the prior art, and provide an elastic putty with excellent performance and convenient construction and a preparation method thereof.

[0004] In order to achieve the above object, the technical solution of the present invention provides a kind of elastic putty, it...
