Abstract
The invention discloses gypsum-based mortar which is prepared by mixing the following ingredients in parts by weight: 400-550 parts of gypsum powder, 450-600 aggregates, 3-5 a retarder, 4.5-5.5 parts of latex powder, 4-5 parts of cellulose and 0.5-1.5 parts of a high-molecular polymer. The gypsum-based mortar has the advantages and beneficial effects that use of existing cement is reduced or even replaced on the basis of meeting the physicochemical characteristics of cement mortar; waste of cement and energy required for producing the cement and the damage to the environment in the cement production process are avoided, so that compared with traditional cement mortar, the gypsum-based mortar is more environment-friendly; and meanwhile, according to the technical scheme, the coagulation time is also shortened, the construction efficiency is improved, and the construction period is shortened. The gypsum-based mortar is suitable for bonding of a lightweight ceramic tile, skimming and leveling of exterior wall concrete and bonding of an insulated plastic extrusion plate and a foam plate. Compared with existing cement mortar and gypsum mortar, the gypsum-based mortar has wider applicability.
Description
Technical field
The present invention relates to a kind of mortar, particularly to a kind of gypsum base mortar.
Background technology
Entering decades, science and technology leap is progressive, and the productivity develops rapidly.Cement is as one of construction material requisite in architectural engineering, and it is widely used in preparation building, the industry such as ornament materials.But impact and the pollution of environment be can not be ignored by a large amount of dust of producing in process of production of cement and harmful substance thereof.The raw material of traditional cement mortar relies primarily on cement to be prepared production, and reasoning is extremely wide, and the application remote-effects of traditional cement mortar Cement Market supply and demand amount just, and what a large amount of productions of cement brought with it is bigger disposal of pollutants therewith.
Summary of the invention
In order to solve the problems referred to above, the present invention provides a kind of gypsum base mortar.The technical program is by utilizing Gypsum Fibrosum and aggregate as major ingredient, achieve compared with traditional cement mortar, ensure that there is the physical property that cement mortar has, reduce the use even replaced current cement, and then reduce the environmental disruption brought due to the production of cement at present；Meanwhile, the technical program can be used for the bonding of lightweight ceramic tile, the granted full of exterior wall concrete and levelling, and the bonding of insulating extruded board and cystosepiment, compared with existing cement mortar and gypsum mortar, has the suitability widely.
A kind of gypsum base mortar in the present invention, is mixed by the dispensing of following weight proportion:
In such scheme, described aggregate is quartz sand.
In such scheme, described Gypsum Fibrosum powder is desulfurization gypsum powder.
In such scheme, described latex powder is redispersible latex powder.
In such scheme, described high molecular polymer is polyvinyl alcohol 2488.
In such scheme, described cellulose is hydroxypropyl methyl cellulose, and the viscosity of hydroxypropyl methyl cellulose is 100000～200000mPa.s.In such scheme, also can add stabilizer.
Advantages of the present invention and having the beneficial effects that: the present invention provides a kind of gypsum base mortar, and has following beneficial effect:
1, meeting on the basis of physicochemical property of cement mortar, reduce the use even replaced current cement, avoid the waste of cement and the energy produced needed for cement, and produce in cement process the destruction to environment, therefore more environmentally-friendly compared with traditional cement mortar, meanwhile, the technical program also shortens setting time, improve efficiency of construction, shorten the construction time；
2, the technical program can be used for the bonding of lightweight ceramic tile, the granted full of exterior wall concrete and levelling, and the bonding of insulating extruded board and cystosepiment, compared with existing cement mortar and gypsum mortar, has the suitability widely.
