Abstract

The invention discloses a special plastic plate capable of improving a diamond wire cutting large system and a preparation method of the special plastic plate. The invention belongs to the technical field of production of plastic plates. The special plastic plate includes, by mass, 65%-90% of ABS resin, 5%-30% of PMMA resin, 1%-10% of a compatilizer, 1%-10% of EAA resin, 0.6%-1.5% of a scale inhibitor, 0.2%-1% of an antioxidant, 0.3%-2% of a lubricant and 0.1%-1% of a surfactant. The special plastic plate is prepared through the steps of raw material mixing, granulation, extrusion molding, polishing, cutting, detection, packaging and the like. The special plastic plate provided by the invention can effectively adjust the pH and conductivity of a large circulation system, has the characteristic of convenience in recycling of silicon materials and ABS / PMMA plastic plates, and can bring obvious benefits of saving energy consumption, reducing cost and improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of plastic plate preparation, and in particular relates to a special plastic plate capable of improving large diamond wire cutting systems and a preparation method thereof. Background technique [0002] During the cutting process of solar silicon wafers, the backing plate, as an indispensable cutting auxiliary material, plays an important role in diamond wire cutting silicon wafers. [0003] Most of the backing plates used in traditional diamond wire silicon wafer cutting are epoxy, phenolic and polyester, and the specific gravity is heavy during use, at 1.5-2.0g / cm 3 , prone to problems such as breakage, broken wires, blocked filter bags, sticky wires, and inconvenient recycling of silicon materials and backing plates, and then gradually replaced by plastic plates, but also accompanied by new problems. General plastic plates cannot maintain The large circulation system is stable, and the conductivity and p...
