The invention relates to a building waterproof material, in particular to a waterproof roof adhesive, which aims to solve the problems in prior roof waterproof material of poor weatherability, easy bubbling and peeling, and poor permeability and air permeability, comprising asphalt, coal tar, waste polystyrene foam, lime and sawdust. Firstly, the waste polystyrene foam is ground to particles; secondly, the coal tar is added into a vessel and heated to 650 to 700 degrees; and the asphalt is added into the vessel, and then the former mixture is agitated homogeneously and keep on warming up to 750 degrees, after the asphalt is dissolved, the mixture is cooled to 400 to 500 degrees; at last, waste polystyrene foam, lime and sawdust are added into mixture successively, the mixture is agitated homogeneously and cooled to a paste shape, and then the finished product is obtained. The building waterproof material has the advantages that: the building waterproof material integrates the advantages of waterproof, heat preservation and heat insulation and has admirable waterproof and heat preservation effect, good weatherability, no fluid and cracks, high adhesive strength; meanwhile, the material meet the national specified standard; more importantly, the aim of waste reuse, pollution treatment, environment protection and cost saving are realized by using the waste polystyrene foam.

The invention discloses an anti-seismic internal mixer, which comprises a working table, a mixing room, a material storage room and a discharge plate. The two ends of the working table are provided with a left fixing seat and a right fixing seat, and the left fixing seat and the right fixing seat There is a mixing room between the seats, and a mixing shaft passes through the mixing room, and the mixing shaft is rotatably connected with the mixing room through a bearing fixed on the mixing room; the two ends of the mixing shaft are respectively arranged on In the sealing block on the left fixed seat and the right fixed seat, the sealing blocks are respectively embedded in the left fixed seat and the right fixed seat, and the material of the sealing block is copper; a lubricating cavity is opened in the sealing block, and the cross section of the lubricating cavity is a circle shape, and the radius is greater than the diameter of the mixing shaft, and the two ends of the mixing shaft extend into the lubricating chamber; the invention ensures the working stability of the device, effectively reduces the noise caused by vibration, and improves the work of the operator. Environmental protection, fast operation, simple structure, convenient and practical, saving production cost and easy maintenance.

The invention discloses a hydrogenating method of unsaturated alkane based on microwaves. The method comprises the following steps: introducing a certain amount of unsaturated alkane into a 25mL microwave container; after replacing air for three times, introducing 20-100psi unsaturated alkane; finally, introducing hydrogen with pressure being 30-250psi for microwave radiation for 1-5 hours, wherein the microwave radiation power is 10-25w and the reaction temperature is 20-100 DEG C; and carrying out a reaction on the unsaturated alkane with hydrogen under a condition without a catalyst so as to hydrogenate and saturate the unsaturated alkane. The method is mild in reaction condition and high in conversion ratio, thereby facilitating cost-saving.
