Embodiment 1

[0028] This embodiment provides an easy-to-cut and easy-to-adhesive double-material hollow solar silicon wafer cutting liner, comprising a B surface layer 1 and an A surface layer 2 arranged on the top of the B surface layer 1, and the B surface layer 1 is uniform along the length direction. A plurality of grooves B are distributed, and a plurality of grooves A corresponding to the grooves B are evenly distributed on the A surface layer 2 , and the grooves B and the grooves A are combined to form a sealed through hole 3 .

Embodiment 2

[0030] On the basis of adopting the technical solution of Example 1, the A surface layer includes the following components calculated by mass percentage: ABS resin 90wt%, cutting adjustment component 9wt%, antioxidant 0.6wt%, lubricant 0.4wt% %. The glue content of the ABS resin is 8wt%, and the preferred acrylocyanide is ABS with medium molecular weight. The cutting adjustment component includes any one or a combination of two or more of polytetrafluoroethylene powder, ultra-high molecular weight polyethylene powder, and polyvinylidene fluoride.

[0031] The surface layer B includes the following components calculated by mass percentage: ABS resin 80wt%, adhesion regulating component 19wt%, antioxidant 0.6wt%, lubricant 0.4wt%. The adhesion regulating component is mineral powder or metal powder, specifically selected from any one or a combination of two or more of calcium carbonate, talc powder, aluminum powder, iron powder and the like. The antioxidant is a compound of ant...

Embodiment 3

Abstract

The embodiment of the invention discloses an easy-to-cut and easy-to-stick double-material hollow solar silicon wafer cutting lining plate and a preparation method thereof. The easy-to-cut and easy-to-adhere double-material hollow solar silicon wafer cutting lining plate comprises a surface layer B and a surface layer A arranged at the top of the surface layer B. A plurality of grooves B are evenly distributed in the surface layer B in the length direction, a plurality of grooves A corresponding to the grooves B are evenly distributed in the surface layer A, and the grooves B and the grooves Aare combined to form sealing through holes. In the easy-to-cut and easy-to-stick double-material hollow solar silicon wafer cutting lining plate provided by the invention, the surface layer A is madefrom self-lubricating cutting-resistant resin powder as a cutting regulator, so that the linear vibration is small, and the conditions of oblique cutting and wafer falling are not easy to occur. Thesurface layer B is made from mineral powder or metal powder as a bonding regulator, so that the bonding of the cutting lining plate and the crystal support can be effectively ensured, and rod fallingis avoided. According to the cutting lining plate, a double-material structure is innovatively adopted, the formula is easy to design and adjust, the surface layer A can better achieve the easy-to-cutperformance, and the cutting quality and stability are guaranteed.

Description

technical field [0001] The invention relates to the technical field of solar photovoltaic silicon wafer cutting, in particular to an easy-cut and easy-stick dual-material hollow solar silicon wafer cutting liner and a preparation method thereof. Background technique [0002] Photovoltaic silicon wafer cutting is an important link in the field of solar energy. The cutting efficiency of silicon wafers and the A-piece rate of silicon wafers are important evaluation criteria for the quality of photovoltaic cutting. Photovoltaic silicon wafers are currently mainly cut with diamond wires, double-wire cutting, and multiple pieces at a time. During the cutting process, the silicon rods are adhered to the crystal support, and there will be a liner between the silicon wafer and the crystal support. The function of the liner is to facilitate After the silicon rod is cut through, it will not hurt the crystal holder. [0003] Silicon wafer cutting liners have been made of glass plates, ...
