Abstract
The invention relates to an emulsified asphalt waterproof agent for cement and fiber base plates and a preparation method of the emulsified asphalt waterproof agent. The emulsified asphalt waterproof agent is characterized by comprising emulsified asphalt fluid, cationic emulsifier, hydrochloric acid, sodium chloride, deionized water, etc. The emulsified asphalt waterproof agent for the cement and fiber base plates can be applied to the waterproofing treatment of a cement plate, a gypsum plate and a fiber plate; and the plates subjected to the waterproofing treatment have the characteristics of being low in water absorption, free from dehalogenation, high in binding force respect to the base plates, and excellent in weather resistance.
Description
Technical field
The present invention relates to a kind of cement, fibre base plate emulsified bitumen water-resisting agent and preparation method thereof, belong to the waterproof construction field.
Background technology
In construction work, use in a large number the sheet materials such as cement plate, plasterboard and fiberboard, its waterproof problem is ubiquitous problem always, traditional water-proof material is take paper Jie asphalt felt as main.In recent years, development along with China's building materials industry, the development of novel building water-proofing material is also very rapid, novel material, product innovation constantly occur, various high polymer waterproof materials and high polymers modified asphalt waterproof material become the main body of waterproof material, wherein, the polyurethanes water-proof material is because it has excellent elasticity, weather resistance, waterproof layer is light, strong with material of construction cementabilities such as cement, mortars, construction is easy to maintenance, component is easy to regulate, can be used for the plurality of advantages such as buildings different sites and good integrity, deeply be subjected to user's welcome.But because it is expensive, therefore polyurethane water-proof paint only is applied in the part occasion, the research and development of China's polyurethane water-proof paint start from nineteen seventies not, generally adopted at that time the coal tar of cheapness and performance brilliance to make to fill plasticised mass, along with the continuous enhancing of people to environmental consciousness, in " Ministry of Construction applies and restriction bans use of technology " bulletin of Ministry of Construction's issue in 2004, classify the coal-tar type polyurethane waterproof material as the forbidding product.Therefore, in recent years, non-coal tar filled-type polyurethane water-proof paint is the main development direction, water-proof asphalt-base polyurethane paint is exactly one of them, but high and compatibility problem has restricted its development due to cost, therefore, studies cheap asphaltic base waterproof paint and has realistic meaning.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the objective of the invention is to provide a kind of cement, fibre base plate emulsified bitumen water-resisting agent and preparation method thereof.It is characterized in that this cement, fibre base plate emulsified bitumen water-resisting agent mainly by: emulsified bitumen liquid, cationic emulsifier, hydrochloric acid, sodium-chlor, deionized water etc. form.
Be mainly by its weight part: 280～350 parts of emulsified bitumen liquid, 3.0～3.8 parts of cationic emulsifiers, 0.5～1.2 part of hydrochloric acid, 1.4～2.2 parts, sodium-chlor, 280～300 parts of compositions of deionized water.
Its cationic emulsifier is a kind of of polyether Glycols or polyether-tribasic alcohol; Its emulsified bitumen liquid is the compositions such as asphaltic liquid, rosined soap, water glass, caustic soda, deionized water.
Its preparation method is:
The preparation of emulsified bitumen liquid
(1) heat water to and boil, add caustic soda to stir, make its dissolving, then slowly add while stirring levigate colophonium powder (particle is less than 5mm), do not make its caking, this mixture is placed on the water-bath that is heated to 90～100 ℃ and constantly stirs, about infusion 90min, naturally cool to faint yellow paste, then add gauge water dilution rosin cream emulsion.
(2) asphalt melting is dewatered under 100～200 ℃, directly only pitch without bubble till, be asphaltic liquid.
(3) rosin cream emulsion is first injected in the stirrer mixing drum, then asphaltic liquid is the thread state and slowly all pours in mixing drum, stir 2～3min, then add the hot water of 80～100 ℃, stir 6～8min, evenly after, be emulsified bitumen liquid.
The preparation of water-resisting agent
