Abstract
The invention discloses a kind of facing mortar, solve the problem that existing facing mortar easily whitens.The present invention is made up of the raw material of following weight portion: aluminate cement 40~80 parts, portland cement 1~30 part, semi-hydrated gypsum 20~30 parts, quartz sand 350~400 parts, latex powder 4~12 parts, cellulose ether 0.1~0.5 part, retarder 0.01~0.5 part, pigment 1~9 part, 75~90 parts of water;Wherein, aluminate cement, portland cement and semi-hydrated gypsum three's sum are 100 parts.The facing mortar of the present invention is without whiting, and stain resistance is good, and water absorption is low, and adhesion strength is high, and Long-Term Properties is good, fast in colour, and water-proof breathable properties is good.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of facing mortar and preparation method thereof.
Background technology
Facing mortar is the China's novel finishing material of one from external introduction, cement-based finishing mortar can be used for external and internal wall surface and ceiling decoration, there is good hydrophobicity and permeability, have good caking property with various basal planes (concrete, cement mortar etc.), not easily peel off and cracking;By selecting the aggregate of different-grain diameter, good texture and wall body decoration effect can be reached.Compared with coating, cement-based finishing mortar is not only constructed simple, quick, has very excellent long-time stability simultaneously;Compared with ceramic tile, cement-based finishing mortar light weight, during as skyscraper facing, will not there is brick phenomenon because of negative blast etc., and there is obvious economy.
The facing mortar problem that there will be whiting in application process being major gelled material with portland cement.Whiten and typically not cause mortar significantly to destroy, mainly affect the organoleptic quality of product, producing in very short time after building of being everlasting comes into operation, particularly when the color of colored mortar is deeper, the white macula that surface is formed can cause the irregular spot that contrast is strong.This is to affect one of major reason that Portland cement base facing mortar promotes the use of.
Aluminate cement has early-strong-fast-hard, resistant to elevated temperatures feature, will not produce Ca (OH) in hydration process2But, due to the transformation at aquation final hydration product crystal formation, it may occur that strength retraction.Portland cement strength development is more stable, but the Ca (OH) produced in hydration process2The whiting of facing mortar can be caused.
Summary of the invention
It is an object of the invention to provide a kind of facing mortar and preparation method thereof, solve the problem that existing facing mortar easily whitens.
To achieve these goals, technical scheme is as follows:
A kind of facing mortar, is made up of the raw material of following weight portion: aluminate cement 40~80 parts, portland cement 1~30 part, semi-hydrated gypsum 20~30 parts, quartz sand 350~400 parts, latex powder 4~12 parts, cellulose ether 0.1~0.5 part, retarder 0.01~0.5 part, pigment 1~9 part, 75~90 parts of water;Wherein, aluminate cement, portland cement and semi-hydrated gypsum three's sum are 100 parts.
Further, described aluminate cement is white aluminate cement;Described portland cement is the white portland cement of strength grade 52.5R;Described semi-hydrated gypsum is alpha-semi water plaster stone.
Yet further, described quartz sand adopts following particle diameter and grating: 40~70 orders, accounts for 55%~65%, and 70~100 orders account for 35%~45%;Described cellulose ether is viscosity is the hydroxyethylmethyl-cellulose of 40000~75000Pa s.
Further, described latex powder is ethene-vinyl acetate-acrylate terpolymer latex powder.
It addition, described retarder is monohydrate potassium;Described pigment is the inorganic red of ferrum oxide.
The preparation method of above-mentioned facing mortar, comprises the following steps:
(1) by aluminate cement, portland cement, semi-hydrated gypsum, quartz sand, latex powder, retarder and pigment dry mixing to uniform state, dry mash is obtained;
(2) adding water in blender, then dry mash adds stirring in blender, mixing time is 2~3 minutes, gets product.
The testing result of facing mortar of the present invention is as follows:
The key property of table 1 facing mortar
The present invention compared with prior art, has the following advantages and beneficial effect:
The present invention adopts the cooperation each other of each raw material, aluminate cement and portland cement are carried out compound, and adds semi-hydrated gypsum and adjust solidifying, and add other raw material, particularly select the quartz sand of appropriate particle size, Ca (OH) can be consumed when hydration process2Generate high sulfur type hydrated calcium aluminate sulfate (AFt) or low sulfur type hydrated calcium aluminate sulfate (AFm), to reach to suppress the purpose of whiting.
The facing mortar of the present invention is without whiting, and stain resistance is good, and water absorption is low, and adhesion strength is high, and Long-Term Properties is good, fast in colour, and water-proof breathable properties is good, and production technology is simple, and application process is convenient, environmental protection simultaneously.
