An organic Si-F water-proofing agent is composed of solvent and the organic Si-F resin prepolymer which is prepared from one or more alkyl siloxane coupling agents and hydroxy F-Si oil through catalytic hydrolysis reaction. Its preparing process is also disclosed. Its advantages are high water-proofing effect and high resistance to solvent, acid, alkali and ageing.

The invention discloses a corrugated asphalt waterproof board. The corrugated asphalt waterproof board is made by using wood fiber as a raw material, forming into a corrugated tile type after performing glue spraying on the surface, and performing impregnation with asphalt. Compared with the coiled material with the expansion and contraction by its own material, due to the corrugated structure andthe self-material expansion and contraction under the frequent changes of temperature, the corrugated asphalt waterproof board of the invention has higher fatigue resistance, the waterproof life which is at least 5 times longer than that of the coil material, and the service life which is at least 25 years (while the quality insurance of the waterproof coiled material is generally within 5 years); the corrugated asphalt waterproof board of the invention has a waveform of a special size and can bear more than 180 kg per square meter; the wood fiber is used as the tire base to enhance the flexibility of the waterproof board so as to enable the waterproof board of the invention to be resistant to repeated folding like paper, thereby achieving strong impact resistance; the corrugated structure is favorable for roof ventilation and dehumidification; the waterproof board of the corrugated structure of the invention is in line contact with the base or partially in surface contact with the base, the position of the corrugated structure is raised and suspended, and the heat dissipation effect is greatly improved compared with the coiled material; and the construction and the replacement are convenient.

The present invention discloses a production process for a novel permeable crystallization water proofing agent. According to the production process, silane, sodium abietate, sodium hydroxide and water are adopted as main raw materials; the raw materials are diluted according to a certain dilution ratio and sequentially added; treatments of heating, uniformly stirring and cooling are performed to form colorless and transparent liquid, which is the novel permeable crystallization water proofing agent, wherein the dilution radio of the silane to the sodium abietate to the sodium hydroxide to the water is 100:50:1:25. The novel permeable crystallization water proofing agent provided by the present invention has the following advantages that: the prepared water proofing agent through the production process provided by the present invention provides excellent waterproof performance and impermeability performance for mortar and concrete, such that the water proofing service life is substantially prolonged, the aging resistance properties of the mortar and the concrete are enhanced, the service life of the whole reinforced concrete building is prolonged; the novel permeable crystallization water proofing agent is nontoxic, and does not cause the pollution to the environment during the production process and the use process.

The invention discloses a waterproof automatic glue dispensing process for lenses, which belongs to the technical field of lens assembly technology and includes a glue dispensing device and a glue dispensing method. The dispensing gland above the dispensing fixture, the dispensing fixture is cylindrical, the size of the inner wall of the dispensing fixture matches the size of the lens, and the upper end of the dispensing fixture is set 3 There are two gaps, the dispensing gland is ring-shaped, and 3 convex corners are set on the dispensing gland. The glue dispensing device of the present invention cooperates with the glue dispensing method and is combined with special glue, so that the operation and detection are convenient and fast, the structure and performance of the processed product are stable, and the work efficiency and product qualified rate are greatly improved.

The invention discloses a waterproof structure and a waterproof method of a drone platform; a waterproof structure of a drone platform includes: a protective shell and a connecting groove plate; the protective shell is fixedly installed on the drone body, and the There are multiple parabolic surface structures in the protective shell; there are four connecting slot plates, which are symmetrically and fixedly installed on one side of the parabolic curved surface of the protective shell, and the shape of the connecting slot plates is a long hyperbolic parabolic panel. The waterproof method of the UAV gimbal is that the falling rainwater flows down along the top parabolic surface of the protective shell to the side parabolic surface, and the rainwater gathers along the curved surface to the apex of the side parabolic surface, and then connects the base along the Flow into the connecting channel plate. The protective casing and the connecting groove plate of the present invention make full use of the properties of the paraboloid to guide the rainwater falling on the fuselage into the connecting groove plate, thereby preventing the rainwater from flowing along the fuselage to the pan / tilt to affect the shooting quality, and improving the waterproof performance of the fuselage .

The invention discloses an elastic waterproof sealant comprising 15-25 parts of alpha-dimethoxysilane-terminated polyether resin, 20-30 parts of gamma-trimethoxysilane-terminated polyether resin, 5-10 parts of dioctyl terephthalate, 40-55 parts of nano-calcium carbonate, 0.1-5 parts of fumed silica, 0.5-5 parts of titanium dioxide, 0.1-1 part of carbon black, 0.1-0.5 parts of an ultraviolet absorber, 0.1-0.5 parts of a light stabilizer, 0.5-1 parts of a dehydrating agent, 0.5-1 parts of an adhesion promoter. The invention also discloses a preparation method of the elastic waterproof sealant, and a roof waterproof structure formed by the elastic waterproof sealant. The elastic waterproof sealant has the advantages that: the elastic waterproof sealant is harmless to human; a roof waterproof structure formed by the elastic waterproof sealant can form a completely closed waterproof layer; construction is simple, and waterproof effect is excellent.
