The invention discloses a surface protecting coating of a stone. The coating is composed of the following components in parts by weight: 1000 parts of cyclohexane, 5-15 parts of triethylene glycol methyl ether, 10-100 parts of nano silicon dioxide, 80-180 parts of vinyl blocked dimethyl siloxane, 2-15 parts of perfluoromethyl vinyl ether and 20-60 parts of a polystyrene-polybutadiene-polystyrene block copolymer. After applying the surface protecting coating of the stone disclosed by the invention, effects of blocking moisture migration and diffusion of salt and alkali can be exerted, so that various diseases such as water spots, saltpetering, rust and cracks after a natural stone is in contact with cement mortar can be avoided better, the bonding strength can be increased, and the service life of the natural stone, in particular of the natural stone for building decoration, is greatly prolonged. The coating has quite good economical benefit and application prospect.

The invention relates to a powder cleaning-free gluing production method of laminated glass, which comprises the following steps: S1, preparing a solution of silica powder with silica powder and water and filtering the solution; S2, spraying silica powder solution on the air surface of outer plate glass and drying sprayed solution to obtain an uniform and thin silica powder layer; S3, matching the outer plate glass processed by the step S2 with inner plate glass; S4, carrying out hot bending of the glass processed by the step S3; and S5, putting a glue sheet between the two pieces of glass processed by the step S4 directly to carry out gluing. The laminated glass does not need to be cleaned in the process of the gluing; and the thin silica powder layer is absorbed by the glue sheet in thehigh-pressure process without influencing the light transmittance of the glass and can overcome the defect of cleaning the silica powder by the water in the prior art. The method at least has the advantages that: because the laminated glass is not needed to be cleaned by the water, sheet washing machines are saved and the obvious effects of energy conservation and consumption reduction are achieved; and the glass is not cleaned by the water, the existence of water stains between the glass are avoided, and problems of the quality, such as degumming, bubbles and the like are prevented.

The invention discloses a blurred vision preventing windscreen wiper which comprises a motor, a speed reducer, a four-bar mechanism, a water-wiping arm and a water-wiping slice, wherein the horizontal section of the water-wiping slice comprises three layers, namely, a first brush layer, a spongy layer and a second brush layer; an extruding structure is respectively connected with each of the two sides of the water-wiping arm; a first motor is fixedly arranged on the upper surface of the water-wiping arm; the extruding structure comprises a first guide rail, a second guide rail, a slide rod, a bracket, an extruding plate, a hauling cable and a return spring. The windscreen wiper further comprises a control structure, wherein the control structure comprises a button switch and an operation rod. The first motor is connected with a power supply through the button switch, the reasonable design of the windscreen wiper is realized, the glass surface is difficult to be blurred in the use process, the water spots are difficult to generate, the observation vision of the driver is not influenced and the technical effect of eliminating potential safety hazard is achieved.
