Abstract

The invention relates to interior wall dry powder mortar, which is prepared from the following raw materials in percentage by weight: 20 to 50 percent of desulphurization gypsum, 20 to 50 percent of artificial sand, 1 to 3 percent of water-retaining agents, 3 to 5 percent of wood fiber and 0.5 to 1 percent of composite retarders. The prepared interior wall dry powder mortar has the advantages that the raw materials use solid waste such as desulphurization gypsum and building decoration waste, so that the resources are saved; the environment pollution is avoided; the manufacturing cost is also reduced. The interior wall dry powder mortar has good workability and water preservation performance; the hardening of a floated coat is fast; the curing period is short; the advantages of strong bonding force, no shrinkage, no hollowing, no cracking, sound absorption, crack resistance and the like are also realized; the interior wall dry powder mortar is suitable for industrial production and popularization and application.

Description

A kind of dry powder for inner wall mortar
Technical field
The present invention relates to a kind of a kind of dry powder for inner wall mortar with solid waste as raw material, belong to solid waste synthesis Using with New Building Materials technical field.
Background technology
With going deep into for reform and opening-up, country is and is developed in protection to the protection of resource and using attaching great importance to, Protection under development.Development of resources and saving are developed simultaneously, and saving is put in the first place, make great efforts to improve resource utilization, to be actively pushed forward Utilizing Resource Pattern, changes from extensive style to intensive style, walks out an economic development for the resource-conserving of suitable China's national situation New approach.
The infrastructure construction of country and building are more and more to the demand of sandstone, and natural sand is fewer and feweri, can adopt Region and river are dug, by exploiting for many years, resource is being reduced rapidly, and the regional natural sand having is exhausted or close to exhaustion, some Area and river, in order to keep natural landscape, protection river dike sill may, protecting ecology to balance, it is stipulated that forbid exploitation.Therefore natural sand Quality and quantity all much can not meet national basis Facilities Construction from now on and other construction the need for, only have for this and actively push away Wide artificial sand, could alleviate this conspicuous contradiction.
It is substantial amounts of in construction and decoration rubbish to be made up of waste concrete, useless fragment of brick, useless ceramic tile, waste mortar etc., by treatment, break Broken, screening, washing etc., producible artificial sand substitute natural sand and prepare dry powder for inner wall mortar.Prepared using construction and decoration rubbish Dry powder for inner wall mortar be used for architectural engineering, it is with low cost, on the one hand solve increasingly deficient natural sand resource problem, it is another Aspect also causes that construction and decoration rubbish is recycled, and improves its value.
The content of the invention
To be protected it is an object of the invention to be directed to current ecological environment, natural sand is fewer and feweri, and construction and decoration rubbish It is more and more, a kind of problem of in need of immediate treatment and resource, there is provided dry powder for inner wall mortar.
To achieve the above object, present invention employs following technical scheme:
A kind of dry powder for inner wall mortar, it is characterised in that the mortar is constituted and its weight/mass percentage composition is:
Desulfurated plaster 20-50%
Artificial sand 20-50%
Water-loss reducer 1-3%
Wood fibre 3-5%
Compound retarder 0.5-1%;
Above-mentioned desulfurated plaster be by drying, calcining, the beta-type semi-hydrated gypsum after levigate treatment, wherein, beta-type semi-hydrated gypsum β- Content >=85% of CaSO41/2 H2O.
Above-mentioned artificial sand is construction and decoration rubbish by after sorting, broken, screening, washing process, the artificial sand of preparation. Meet《GB/T25176-2010 concrete and mortar recycled fine aggregate》Standard.
Above-mentioned water-loss reducer is the one kind in hydroxyethyl cellulose, HEMC, hydroxypropyl methyl cellulose Or two kinds.
Above-mentioned wood fibre be by natural reproducible timber by chemical treatment, Mechanical Method processing obtain it is easy to be scattered Organic wadding fibrous material, length is 0.5-2mm.
Above-mentioned compound retarder by 5-15% malic acid, 10-30% amion acetic acids, 10-30% disodium ethylene diamine tetraacetates, 25-45% calcium increasing agents compounding is formed.
A kind of preparation method of above-mentioned dry powder for inner wall mortar of the invention, is by desulfurated plaster, artificial sand, water-loss reducer, wood Matter fiber, compound retarder composition;The mass percent constituted according to above-mentioned dry powder for inner wall mortar is weighed:It is desulfurated plaster, artificial Sand, water-loss reducer, wood fibre, compound retarder, are added sequentially in mixer, stir, you can a kind of interior wall is obtained and does Powder mortar.
Dry powder for inner wall mortar of the present invention has following features:
1st, dry powder for inner wall mortar prepared by the present invention, its raw material is using the solid waste such as desulfurated plaster, construction and decoration rubbish, section About resource, it is to avoid environmental pollution, also reduces cost of manufacture.
2nd, mechanical execution by dry powder for inner wall mortar of the invention adds appropriate water, there is good workability, water-retaining property. Coat of plaster hardening is fast, and curing cycle is short.With cohesive force it is strong, do not shrink, not hollowing, be not cracked, sound-absorbing, high-strength, cracking resistance etc. are excellent Point.
3rd, dry powder for inner wall mortar fire protecting performance of the invention is good, and when there is fire, gypsum hardenite has mass crystallization water Discharged under heat effect, form steam, spreading for flame is blocked, while being absorbed in whole dehydration substantial amounts of Heat, so as to improve fire resistance.
4th, the dry powder for inner wall mortar has respiratory function, and gypsum base mortar has automatic moisture absorption and is automatically releasable moisture content function, Within optimum range, comfortable family life environment is created such that it is able to by indoor humidity control;
5th, the dry powder for inner wall mortar belongs to air hardening section bar material, in construction, as long as mixing water does not freeze, and also can be in the winter time(-5℃ More than)Constructed, its quality requirement is not influenceed.
