Abstract
The invention relates to a high-strength water-proof gypsum plaster and a production method thereof. The inventive high-strength water-proof gypsum plaster is made from the following materials in weight proportions: 10-99% of gypsum-based composite binding agent, 0-90% of aggregates, 0.08-4% of additives and 0-16.1% of adsorbent. The production method comprises the following steps: weighing raw materials at the given ratio, drying the aggregates, mixing all raw materials, and packaging. The inventive high-strength water-proof gypsum plaster has high strength and good water resistance; can be made from chemical gypsum materials without needing calcination, such as desulfurized gypsum, phosphogypsum, fluorgypsum and citric acid gypsum; and has the advantages of low production cost, energy conservation, discharge reduction and environmental friendliness.
Description
Technical field
The present invention relates to compound coating material of a kind of high-strength waterproof gypsum base and production method thereof, specifically, relate to a kind of high strong water resistant brushing gypsum and production method of wiping one's face in inner wall of building, exterior wall and shingle surface thereof that be used for
Background technology
Brushing gypsum has with the base material bonding firm, and fast solidifying does not shrink during setting and harden, easy construction, characteristics such as working efficiency height can avoid that cracking, hollowing appear in traditional cement sand plaster layer, the shortcoming that comes off, and are specially adapted to wiping one's face of gas concrete metope and shear wall metope.Abroad, the use of brushing gypsum is quite general, and as Germany, the plastering material more than 70% is a brushing gypsum, and Britain's brushing gypsum is 50% of a gypsum total amount.The research and development of China's brushing gypsum start from the beginning of the eighties in last century, four big classes have now been formed, ten kinds, ten kind brushing gypsums of this four big class are classified from the gypsum powder phase composite, i.e. half water brushing gypsum, II type anhydrite whitewashes gypsum, Mixed-Phase Plastering Gypsum (semi-hydrated gypsum and anhydrite II-s mixing brushing gypsum, early stage, intensity was obtained by the semi-hydrated gypsum aquation, and later stage intensity is obtained by anhydrite II-s aquation, make on the brushing gypsum behind the wall, have successive hydration process and gain in strength process), and gypsum, the lime mixed plaste for plastering.In first three class brushing gypsum, can be divided into surface layer, bottom and insulation brushing gypsum again, and gypsum, lime mixed plaste for plastering only are applicable to surface layer, have constituted the brushing gypsum of ten kinds.
In above-mentioned ten kinds of brushing gypsums, behind the brushing gypsum hydration and hardening, its basic structure is dihydrate gypsum, and dihydrate gypsum intensity is low, water resistance is poor (coefficient of softening is low), and needs calcining, production cost height.China territory is vast, thing, north-south climate are widely different, the Northwest is short of rain, dry air, and southern area is rainy, there was dampness in the air, plum rain season particularly, relative air humidity be more than 80%, and no matter the north and south, its kitchen and toilet always are in the damp atmosphere state, and traditional brushing gypsum should not use in these environment.Therefore, need to improve the water resistance of brushing gypsum.
Moreover the at present annual industry byproduct phosphogypsum of China has 2,000 ten thousand tons, and with annual 15% speed increment; The annual desulfurated plaster that produces has 4,000,000 tons, and also will increase desulfurated plaster newly more than 2,000 ten thousand tons every year after 2010; And, (wherein fluorgypsum is a dehydrated gyp-to also have a large amount of fluorgypsums, lemon gypsum, boron gypsum, titanium gypsum, salt gypsum etc., dehydrated gyp-is also referred to as anhydrite, desulfurated plaster, phosphogypsum, lemon gypsum, boron gypsum, titanium gypsum and salt gypsum etc. are dihydrate gypsum), these industry byproduct gypsum claim chemical gypsum again, only have to be used for cement additire on a small quantity, and majority is in the stacking state, not only take a large amount of soils, and contaminate environment and groundwater resource.
Summary of the invention
The objective of the invention is to overcome some defectives that existing brushing gypsum exists; a kind of high strong water resistant brushing gypsum is provided; and can utilize desulfurated plaster, phosphogypsum, fluorgypsum, lemon gypsum etc. to need not the incinerating chemical gypsum to be prepared as starting material; both can reduce the production cost of brushing gypsum; help energy-saving and emission-reduction again, the protection environment.
The objective of the invention is to be achieved through the following technical solutions:
The present invention's high strong water resistant brushing gypsum is made up of following material and weight proportion: gypsum base composite gelled material 10%～99% (preferred 40%～70%), aggregate 0～90% (preferred 30%～69%), additive 0.08～4%, sorbent material 0～16.1%;
Described gypsum base composite gelled material is made up of following constituent materials: mixed gypsum powder 40%～80% (preferred 50%～70%), active admixture 10%～45% (preferred 15%～35%), alkali-activator 4%～15% (preferred 6%～12%), re-dispersible glue powder 0.1%～2%, setting accelerator 0%～6% (preferred 1%～3%), lime 0～5%, hardening accelerator 0～1%, water reducer 0～1%, fiber 0～1.0%;
Described mixed gypsum powder is to be selected from a kind of in dihydrate gypsum powder, the anhydrite powder or their mixture;
Described dihydrate gypsum powder can be natural dihydrate gypsum powder, desulfurated plaster powder, pretreated phosphogypsum powder or pretreated lemon terra alba; Screening formulation, dihydrate gypsum: anhydrite=30%～90%: 10%～70%; Can add in case of necessity 0～15% semi-hydrated gypsum (
Or
