The invention relates to the technical field of gloss paint, and in particular relates to natural environment-friendly plant gloss oil. The natural environment-friendly plant gloss oil is characterized by comprising the following components by weight percent: 42-50% of natural plant secreted oil, 10-12% of bisphenol A acrylate methacrylate, 5.5-16% of ethoxylated pentahydroxy methyl oligomer, 6-8% of pentaerythritol hexapropionate, 5-6.5% of ethoxylated hydroxymethyl dimethylmethane, 7-9% of pentahydroxymethyl propane dimethyl ester, 3.5-5.5 % of dioxymethyl separating agent, 5.5-7% of polyester moisture drying agent and 0.5%-1.5% of flatting agent. The natural environment-friendly plant gloss paint provided by the invention has high environment-friendly index number, is plump and soft and has good hand feeling; the gloss oil has high transparency, and natural color of wood can be restored; the gloss oil is hard and wear-resistant, and has good scratch resistance; the gloss oil is clean-smelling, healthy, environment-friendly, good in scratch resistance and wear resistance and strong in adhesive force; and the gloss oil has good hardness, is free of after-tack and resists sea water.

The invention relates to a lock catch type combined heat insulating component of a building. The lock catch type combined heat insulating component of the building comprises a component body of which the outer surface is rectangular, wherein a groove of which the width is half that of the rectangle is formed in the middle of one end surface of the component body; a row of lock catches is arranged on the side surface of the groove, and the space between every two adjacent lock catches is greater than the length of each lock catch body; the distance from each lock catch to the top surface of the groove is less than the distance from each lock catch to the bottom surface of the groove; a plurality of bosses are arranged on the bottom surface of the groove. The invention further discloses a composition of the lock catch type combined heat insulating component of the building. The lock catch type combined heat insulating component of the building and the composition thereof have the advantages that the working hours can be saved, the quality can be ensured, the environmental protection indexes are high, the material consumption is reduced, the labor can be saved, and the cost is low.

The invention discloses a 1-methyl-2-cyano-3-aliphatic substituted pyrrole compound synthesis method, which comprises: carrying out a three-component addition reaction on terminal aliphatic hydrocarbon, trimethylcyano silane and N,N-dimethylformamide according to an equal chemical molar weight ratio under the catalytic action of ammonium iodide to generate a 1-methyl-2-cyano-3-aliphatic substituted pyrrole compound; and after the reaction is finished, washing the reaction system with saturated sodium sulfite, and extracting the water phase with ethyl acetate to obtain the high-purity 1-methyl-2-cyano-3-aliphatic substituted pyrrole compound. According to the invention, the method is good in product selectivity, high in yield, simple in separation process, low in catalyst cost, environmentally friendly and beneficial to industrial production and application.

The invention discloses a sheet-like laminated all-solid supercapacitor and a preparation method thereof, belonging to the technical field of capacitors and their preparation. A sheet-like laminated all-solid-state supercapacitor includes a capacitor shell, and a blind hole is dug at the top of the side of the capacitor shell. An all-solid supercapacitor core is placed inside the capacitor case, electrodes are connected to both ends of the all-solid supercapacitor core, and paste-variable conductive silver paste is connected between the inner wall of the capacitor case and the blind slot and the all-solid supercapacitor core. Layer, on the inner wall of the capacitor shell, there is a prefabricated thin layer of pasted conductive silver paste. It is relatively simple to prefabricate the thin layer of pasted conductive silver paste alone, and it will not pollute the capacitor shell. When installing an all-solid supercapacitor core, use The thin layer of pasted conductive silver paste is deformed, so that the conductive silver paste layer fully contacts the side end of the all-solid supercapacitor core, improves the adhesion between the conductive silver paste layer and the all-solid supercapacitor core, and improves the production quality of the all-solid supercapacitor and the later stage. Use efficiency.

The invention discloses an asphalt pavement pothole repair capsule and its preparation and construction method. The outer shell is made of a material that is easy to be broken at high temperature, the mixture of asphalt and heating medium is used as the core, and it is obtained by wrapping it with aggregate; the raw materials are calculated as mass percentage. 7%-12% road petroleum asphalt, 7%-12% heating medium, 15%-40% alginate-calcium chloride polymer and 40%-60% aggregate. By encapsulating the asphalt mixture and transporting it in bags, the energy consumption of the hot-mix asphalt mixture during transportation is saved, and the problem of poor storage stability of the asphalt mixture is effectively solved. In addition, using the repair capsule combined with induction heating technology to repair the pits in the asphalt concrete pavement with microwave or electromagnetic heating, the rapid repair and maintenance of the asphalt concrete pavement can be realized without reducing its road use and mechanical properties. Preventive maintenance, good economy, prolong the service performance of asphalt pavement.
