Water-permeable pavements using organic binders cannot be used on automobile pavements because of their low strength. Adding organic binders can increase the strength, but the water permeability will decrease due to the reduction of voids. Odor and volatile gas affect the health of workers and surrounding residents, materials are easily adsorbed on construction equipment, and cleaning is time-consuming

[0020] The invention relates to an inorganic material binder and a preparation method thereof.
[0021] The inorganic material binder includes: a first active agent, a second active agent, a shrinkage reducing agent, an anti-white bloom agent, an inorganic pigment and a fiber;
[0022] Wherein, the first active agent is 1% to 3% of the mass of the second active agent, the shrinkage reducing agent is 0.5% to 1.5% of the mass of the second active agent, and the white bloom preventer is the second active agent 3%-6% of the mass of the second active agent, the inorganic pigment is 10%-20% of the mass of the second active agent, and the fiber is 1%-2.5% of the mass of the second active agent.
[0023] The first active agent in the inorganic material binder includes: a defoamer, a water reducer and a tackifier; the mass ratio of the defoamer to the water reducer is 0.1 to 0.3, and the water reducer The mass ratio to the tackifier is 0.8-1.2.
[0024] The second active agent in the...

Abstract
The invention relates to an inorganic material adhesive comprising: a first activator, a second activator, a reduction decreasing agent, an efflorescence prevention agent, an inorganic pigment and fibers. The mass of the first activator is 1-3% of that of the second activator. The mass of the reduction decreasing agent is 0.5-1.5% of that of the second activator. The mass of the efflorescence prevention agent is 3-6% of that of the second activator. The mass of the inorganic pigment is 10-20% of that of the second activator. The mass of the fibers is 1-2.5% of that of the second activator. The invention also relates to a preparation method of the inorganic material adhesive. The inorganic material adhesive, when being used in construction of a water permeable pavement, enables the pavement to have high water permeation coefficient, high water retention, high strength, high durability and no environment pollution, wherein the water permeation coefficient is 2.6-6.3 mm/s, the water retention rate is 100-160 l/m<3>, compressive strength is 20-55 MPa and flexural strength is 2.5-5.8 MPa. The preparation method avoids dust pollution and is lower than 5 mg/Nm<3> in dust emission. The inorganic material adhesive has stable components and is lower than 0.05% in component fluctuation, so that the system has high operation rate being more than 98%.
Description
technical field [0001] The invention relates to the technical field of binders, in particular to the technical field of inorganic material binders, and specifically refers to an inorganic material binder and a preparation method thereof. Background technique [0002] Economic and social development brings unsuitable environment at the same time: airtight surface improves traffic and road conditions, but also has significant adverse effects on urban ecology and climate environment. Permeable pavement can effectively improve the environment. Water-permeable pavements using organic binders cannot be used on automobile pavements because of their low strength. Adding organic binders can increase the strength, but the water permeability will decrease due to the reduction of voids. The pavement will age due to long-term ultraviolet radiation and reduce durability. Smelly volatile gas affects the health of workers and surrounding residents. Materials are easily adsorbed on construc...
