Abstract
The invention belongs to the field of building materials and particularly relates to an ecotype high-strength modified gypsum powder. The ecotype high-strength modified gypsum powder is prepared from industrially desulphurized or natural gypsum powder, ground slag, polyvinyl alcohol, fired alunite powder, melamine and borax. The ecotype high-strength modified gypsum powder meets various technical requirements of natural gypsum powder, and is greatly improved in strength grade, runnability, durability and construction property.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of environmental high-strength modified landplaster.
Background technology
Terra alba is as one of five large gelatinous materials, occupy an important position in national economy, being widely used in numerous Application Areass such as building, building materials, industrial mould and artistic model, chemical industry and agricultural, food-processing and medicine beauty treatment, is a kind of important industrial raw materials.In recent years, along with the development of plastering industry, the terra alba of various different purposes is also promoted, in succession particularly at building material industry, along with being on the increase of Highrise buildings changes progressively going deep into of work with national wall, terra alba has become the commodity in short supply of building materials market.Building gypsum plaster common is at present feature with whiteness, and have suitable intensity.Usual terra alba is fired and levigately to form by the plaster of paris.
Although traditional terra alba can meet every technical requirements instantly, along with being on the increase of Highrise buildings, more and more higher to the requirement of strength of terra alba, traditional terra alba cannot meet the needs of construction material.
Summary of the invention
Lower in order to solve above-mentioned terra alba intensity, the technical problems such as the needs of construction material cannot be met, the present invention proposes that a kind of strength grade is high, mobility, weather resistance and have good workability and rational environmental high-strength modified landplaster of filling a prescription.
In order to achieve the above object, the technical solution adopted in the present invention is as follows:
The raw materials by weight portion proportioning of environmental high-strength modified landplaster is as follows:
As preferably, the fineness order number of described slag powders is 500-1250 order, and whiteness reaches more than 75, and within 7 days, activity index reaches more than 80 parts.
As preferably, described industrially desulfurized or plaster of paris powder fineness order number is 80-150 order, and accurate denseness reaches 0.63, and within 2 hours, anti-folding reaches 1.1MPa, and ultimate compression strength reaches 4.0MPa, and the presetting period reaches 3.0 minutes, and final setting time is no more than 30 minutes.
The invention provides a kind of preferred proportioning: the raw materials by weight portion proportioning of environmental high-strength modified landplaster is as follows:
As preferably, the fineness order number of described slag powders is 500 orders.
As preferably, the fineness order number of described natural gesso is 150 orders.
The present invention also provides a kind of preferred proportioning in addition: the raw materials by weight portion proportioning of environmental high-strength modified landplaster is as follows:
As preferably, the fineness order number of described slag powders is 500 orders.
As preferably, the fineness order number of described industrially desulfurized terra alba is 100 orders.
Beneficial effect of the present invention: adopt the high-strength modified landplaster of the ecotype provided by the invention to meet every technical requirements of general natural gesso, and can significantly improve terra alba strength grade, and increase the mobility of terra alba, weather resistance and workability.
