The invention discloses a gob-side roadway retaining method based on roof cutting of a soft roof plate. According to the gob-side roadway retaining method based on roof cutting of the soft roof plate, a movable stop lever air leakage preventing device is used for assisting in roadway formation, so that roadway formation achieved by filling walls with concrete in the prior art is replaced; the adopted stop lever air leakage preventing device is an assembly, and the whole stop lever air leakage preventing device is of a square tubular structure and comprises an upper cap plate, folding air cloth, a single hydraulic prop, a steel wire mesh and a lower shoe plate; the steel wire mesh is hung on the side close to a gob; and the folding air cloth is fixed to the side close to a roadway. The stop lever air leakage preventing device and a working face advance to be dismounted and mounted synchronously and can be moved to another place to be used again, after the stop lever air leakage preventing device is dismounted and moved, liquid concrete is sprayed onto a wall formed by rocks exposed out of one side of the stop lever air leakage preventing device, and a series of technique means such as gap blocking and sealing are adopted, so that compared with a gob-side roadway retaining method in the prior art, the gob-side roadway retaining method based on roof cutting of the soft roof plate has the beneficial effects that the roadway forming speed is high, the efficiency is high, the safety performance is good, the concrete filling work amount is small, and the cost is low.

The invention relates to an automobile roof coating robot sucker claw, which comprises a main frame, a connecting flange which is arranged in the middle of the upper end face of the main frame and connected with a robot, a first group of suckers, a second group of suckers, an unhooking prevention device, a third group of suckers and a fourth group of suckers. In the invention, the claw breaks limitation on special clamps; a photographic calibration technique and a structure in which the pivot angle of the claw sucker bracket is adjustable and in which floating suckers are arranged in the middle are adopted, so multiple types of switching is realized and the coating beat and positional accuracy are improved greatly in production; and the design of the claw is in accordance with the actual condition of the operation of the robot.

The present invention provides an infrared reflective coating composition comprising, by weight percentage based on the total dry weight of the composition, 0.1% to 50% polymeric hollow particles, from 0.1% to 70% pigment particles and from 20% to 80% at least one polymeric binder, wherein the volume average particle size of the polymeric hollow particles is from 0.3 to 1.6 μm; and wherein the volume average particle size distribution of the polymeric hollow particles is such that 90% of particle lies within ±10% of the volume average particle size. The coating composition is suitable for exterior architectural or industrial applications especially as an elastomer roof coating.

The invention provides for the use of coating compositions based on one or more mineral binders, one or more polymers, one or more fillers, and, if desired, one or more additives for producing roof coatings, the coating compositions comprising at least 50% by weight of polymers, based on the dry weight of the polymers and of the mineral binders.

The invention discloses a car-roof coating material, which comprises: by mass, 20-40% parts of a resin, 1-5% parts of pigments, 1-5% parts of a curing agent, 10-20% parts of a solvent, and 1.4-1.8% parts of additives. The car-roof coating material also comprises 20-40% parts by mass of a metal / multiphase ceramic composite, which is Ni.Cr-SiC / Al2O3. According to the invention, corrosion resistance, hardness and strength of the coating itself can be effectively improved by adding the metal / multiphase ceramic composite into the coating, various disasters can be better prevented, ultraviolet radiation can be better resisted by adding a light screener and a radical scavenger, and service life of a car roof can be further effectively prolonged.

The present invention relates to a roofing rigid waterproof layer structure and a construction method thereof. A rigid waterproof layer is obtained through processes of surveying and setting out, arranging a dividing strip layer, pouring a bottom layer waterproof layer, laying a waterstop belt layer and pouring an upper layer waterproof layer and the like, and a plurality of dividing joint structures are staggered in the rigid waterproof layer. The roofing rigid waterproof layer structure has the beneficial effects that a dividing joint is separated from external environment by a waterstop belt, and the top of the waterstop belt is provided with the dividing joint and a waterproof coating protective layer; construction progress is accelerated, cost is saved to a certain degree, concrete moulding effect is good, and the surface is flat without ponding cold ponds; and after joint material and waterproof coating are aged and not waterproof, due to the fact that the waterstop belt is disposed and the surface layer dividing joint is relatively shallow, moisture is not easy to leak and can be rapidly evaporated, temperature telescoping deformation of the concrete rigid waterproof layer is satisfied, waterproof performance of the dividing joint is largely enhanced, and service life period of roofing waterproof is prolonged.
