Problems solved by technology

[0002] PVB is also known as polyvinyl butyral ester. During the production process of PVB foaming products, it needs to enter the foaming furnace to raise the temperature for foaming. The current foaming temperature needs to be controlled at 220-230°C. If the temperature is lower than 220 °C, foaming is not easy, the foaming effect is poor, affecting product quality
[0003] In order to achieve sufficient foaming and achieve a better foaming effect, the foaming temperature must be controlled to 220-230°C. The high foaming temperature will cause energy waste and increase production costs on the one hand; on the other hand, high temperature will make PVB Some raw materials in the product volatilize, resulting in waste of raw materials and affecting the overall quality of PVB products

Abstract

The invention discloses a master batch which is prepared from the following raw materials in percentage by weight: 8-12% of glycerinum, 12-18% of urea, 50-55% of zinc cyanurate and 20-25% of glycerinum zinc. The preparation method of the master batch comprises the following steps: stirring and mixing the glycerol, the urea, the zinc cyanurate and the zinc glyceroxide at a high speed according to the weight percentage, and then heating, extruding and granulating to prepare the master batch. The master batch provided by the invention is added into a PVB foamed product, so that the foaming temperature is reduced to 180-200 DEG C on the premise of ensuring high and stable foaming ratio.

Description

technical field [0001] The invention relates to the technical field of production of PVB foamed products, in particular to a masterbatch for reducing foaming temperature and its application. Background technique [0002] PVB is also known as polyvinyl butyral ester. During the production process of PVB foaming products, it needs to enter the foaming furnace to raise the temperature for foaming. The current foaming temperature needs to be controlled at 220-230°C. If the temperature is lower than 220 ℃, foaming is not easy, the foaming effect is poor, and the product quality is affected. [0003] In order to achieve sufficient foaming and achieve a better foaming effect, the foaming temperature must be controlled to 220-230°C. The high foaming temperature will cause energy waste and increase production costs on the one hand; on the other hand, high temperature will make PVB Some raw materials in the product volatilize, resulting in waste of raw materials and affecting the ove...
