The invention discloses a self-leveling penetrating crystallization waterproof coating and application thereof. The waterproof coating comprises component A and component B, wherein component A comprises water and polyvinyl alcohol, and component B comprises a base material and an active crystallization chemical substance. In terms of mass percentage, the polyvinyl alcohol in component A is 10%-20%, and component A does not contain other film-forming resins except polyvinyl alcohol, and component B further comprises 0.1%-0.8% of tartaric acid. The waterproof coating can achieve sufficient penetration of active crystallization substances independently without a maintenance process by self-locking water, can improve the waterproof performance of a concrete base layer and can form a waterproof layer itself, can seal a ventilation channel between concrete and an outside, prevent the generation of bubbles during the construction of a next waterproof or decorative coating, and has excellent self-leveling performance, can easily achieve a leveling function for a concrete foundation, for example, a waterproof coiled material can be directly laid thereon without additional operations such as grinding and leveling.

The invention discloses a self-leveling capillary crystalline waterproof coating and a preparation method thereof, the waterproof coating comprises a component A and a component B, the component A comprises water and polyvinyl alcohol, the component B comprises cement, quartz sand, an active crystalline chemical substance and tartaric acid, and the component A and the component B are respectively prepared during preparation; uniformly mixing the components in the component A to obtain the component A; uniformly mixing the components in the component B to obtain the component B, and mixing the component A and the component B during use; the waterproof coating can independently complete sufficient permeation of active crystalline substances through self-water-locking without a maintenance process, can improve the waterproof performance of a concrete base layer, can form a self-waterproof layer, can seal a ventilation channel between concrete and the outside, prevents construction bubbles of a next waterproof or decorative coating from being generated, and improves the waterproof performance of the concrete base layer. In addition, the leveling agent has excellent self-leveling performance and can easily achieve the leveling function on a concrete foundation, for example, waterproof coiled materials can be directly laid on the leveling agent, and extra operations such as polishing and leveling are not needed.

The invention relates to the field of solid waste resource utilization research, in particular to colored self-leveling red-mud-based fully-recycled high-strength mortar and a preparation method thereof, and the colored self-leveling red-mud-based fully-recycled high-strength mortar comprises the following components in parts by mass: 60-100 parts of solid waste cementing material, 30-50 parts of mortar recycled aggregate, 5-10 parts of recycled pigment and 2-10 parts of self-leveling agent.

Therefore, carbon emission is reduced, environmental pollution is reduced, more material choices are provided for the building industry, and different engineering requirements are met.

The invention discloses a graded-aperture flexible aerogel heat-insulating coating capable of serving for a long time in an environment of 1100 DEG C. The graded-aperture flexible aerogel heat-insulating coating belongs to the technical field of heat-insulating coatings and comprises the following components in parts by mass: 10-30 parts of aluminum dihydrogen phosphate, 10-35 parts of water, 10-30 parts of gamma-glycidoxypropyltrimethoxysilane, 5-17 parts of alpha-aluminum oxide and 1-3 parts of an emulsifier. 1-3 parts of a defoaming agent, 1-6 parts of aerogel nanofibers and 3-5 parts of aerogel powder. The back temperature of the aerogel coating with the thickness of 2-3mm can be controlled below 300 DEG C under the condition that the front surface is heated at 1050-1100 DEG C, so that the aerogel coating meets the heat insulation requirements of metals such as steel structures and the like, and has excellent fireproof performance. The coating is simple in preparation process, low in production cost, excellent in heat insulation and fireproof performance and wide in application prospect.

This invention belongs to the field of micro-coating protection and discloses an organosilicon aerosol coating for waterproofing precision instruments and its preparation method. The organosilicon aerosol coating comprises, by weight, 4-6 parts of fluorinated organosilicon, 2-3 parts of organosilicon-acrylate resin, 30-40 parts of a first solvent, 20-30 parts of a second solvent, 1-1.5 parts of a release agent, 0.5-1 parts of a leveling agent, and a certain amount of propellant. This invention uses a first solvent and a second solvent with different volatility properties to improve the self-leveling and film-forming quality of the microfilm after spraying, reducing surface micropore defects caused by excessive evaporation and forming a good waterproof layer. Through the synergistic effect of fluorinated organosilicon and organosilicon-acrylate resin as film-forming materials, the waterproof coating formed with the release agent and leveling agent possesses both long-lasting waterproofing and peelability. When used for the protection of precision instruments, the coating can be peeled off after a certain protection period without leaving residual pollution on the instrument surface.

The invention discloses a high-strength machine mahjong and a manufacturing method thereof, and mainly relates to the technical field of mahjong machines. The machine mahjong comprises a mahjong shell, a magnet is arranged in the mahjong shell, filler is arranged between the magnet and the inner wall of the mahjong shell, a font groove is formed in the front face of the mahjong shell, and fonts are poured in the font groove.
