Solar battery piece packaging glue structure and preparation method thereof

The invention relates to a solar battery piece packaging glue structure and a preparation method thereof. The structure comprises a packaging glue layer and at least one partitioning membrane layer, or comprises a packaging glue layer, at least one layer of partitioning membrane and at least one adhesive layer distributed on one side, which is close to a battery piece, of the partitioning membrane, wherein the partitioning membrane is compounded with the packaging glue layer, or the partitioning membrane is compounded with the packaging glue layer and the adhesive layer; the flowability of the partitioning membrane is smaller than that of the packaging glue layer. According to the solar battery piece packaging glue structure, as one layer of the partitioning membrane with very low flowability is compounded with the packaging glue and the flowability of the partitioning membrane self is lower than that of the packaging glue, the packaging glue is harder to overflow, and moreover a good partitioning function is achieved for overflowing of the packaging glue with high flowability. When the structure is laminated, the packaging glue of a cross-linking system with high flowability at a lower layer can be fused with the partitioning membrane with low flowability at an upper layer at high temperature, so that sufficient binding force can be still maintained.

Preparation method of modified emulsified asphalt for ultra-thin wearing layer

The invention discloses a preparation method of modified emulsified asphalt for an ultra-thin wearing layer. The preparation method comprises the following steps: (1) preparing materials of asphalt, a modifying agent, a cationic quick-cracking type emulsifying agent and water according to the following matching ratio: 45.0-68.0% of asphalt, 3.0-4.0% of modifying agent, 0.25-0.45% of cationic quick-cracking type emulsifying agent, 0.5-2.0% of stabilizing agent, 1-5% of auxiliary agent and the balance of water; (2) rising the temperature of the asphalt to 160-189 DEG C, adding the modifying agent, stirring uniformly, grinding by a grinding machine, and controlling the particle size of the modifying agent to be less than 5mum, thereby preparing the modified asphalt; (3) adding the emulsifying agent and the stabilizing agent into water with the temperature of 40-60 DEG C, and adjusting the pH value to be 1.5-3 by using the auxiliary agent, thereby preparing soap liquid; and (4) preparing the modified asphalt obtained in the step (2) and the soap liquid in proportion by an emulsifying device. By virtue of the scheme, the obtained modified emulsified asphalt for the ultra-thin wearing layer has the advantages of strong adhesive property, high solid content and fast emulsion-breaking speed.

Heat-conducting silicone grease and preparation method thereof

The invention provides heat-conducting silicone grease and a preparation method thereof. The heat-conducting silicone grease is prepared from the following components in parts by mass: 100 parts of polydimethylsiloxane, 5-20 parts of modified silicone oil, 1300-1800 parts of modified heat-conducting composite powder and 2-10 parts of a thermal gel additive. Through grading of spherical aluminum oxide with different particle sizes and by utilizing the characteristics of strong surface effect and small-size effect of nano quantum dots, cavity gaps dispersed among aluminum oxide particles are uniformly filled, so that the thermal resistance of the product is effectively reduced, the thixotropic index of the heat-conducting silicone grease is improved, and the heat-conducting silicone grease is endowed with a shear thinning characteristic; and meanwhile, the heat-conducting silicone grease has enough binding power, and the aging property of the heat-conducting silicone grease is improved.Meanwhile, the particle size distribution of the filler is strictly controlled, and the selected filler is very narrow in particle size distribution and has good monodispersity; the filler with the particle size larger than 20 microns is screened out through sieving processing, so that it is ensured that the filler grading effect is good, and gaps are avoided; and the heat-conducting silicone grease is low in thermal resistance value and excellent in aging performance.
