Problems solved by technology

[0002] PVB is also known as polyvinyl butyral ester. During the production process, PVB foam products need to enter the foaming furnace for foaming. It is inevitable to wait for a period of time before entering the foaming furnace. Currently, it is carried out in advance during the waiting stage. Foaming will result in partial consumption of the foaming agent. After entering the foaming furnace, it will either not be able to foam directly, or it will need to be forced to foam by controlling the temperature, resulting in a product that is not delicate and inelastic, affecting product quality, and causing product failure. The expansion ratio is unstable, which affects the stability of product quality

Embodiment 1

[0025] Example 1: A foaming inhibitor prepared by the following steps: mixing acid anhydride and nonanol, and reflux reaction at a temperature of 180° C. for 2 hours; the mass ratio of the acid anhydride to nonanol is 1:1, so Described acid anhydride is phthalic anhydride and maleic anhydride, and the mass ratio of phthalic anhydride and maleic anhydride is 3:7.

Embodiment 2

[0026] Example 2: A foaming inhibitor prepared by the following steps: mixing acid anhydride and nonanol, and reflux reaction at a temperature of 190° C. for 1 h; the mass ratio of the acid anhydride to nonanol is 1:1, so Described acid anhydride is phthalic anhydride and maleic anhydride, and the mass ratio of phthalic anhydride and maleic anhydride is 3:7.

Embodiment 3

[0027] Example 3: A foaming inhibitor prepared by the following steps: mixing acid anhydride and nonanol, and reflux reaction at a temperature of 185° C. for 1.5 h; the mass ratio of the acid anhydride to nonanol is 1:1, The acid anhydride is phthalic anhydride and maleic anhydride, and the mass ratio of phthalic anhydride and maleic anhydride is 3:7.

Abstract

The invention discloses a foaming inhibitor, which is prepared by the following steps: mixing anhydride and nonanol, and carrying out reflux reaction at the temperature of 180-190 DEG C, wherein the mass ratio of the anhydride to the nonanol is 1: 1, the anhydride is phthalic anhydride and maleic anhydride, and the mass ratio of the phthalic anhydride to the maleic anhydride is 3: 7. The obtainedproduct is fine and smooth in hand feeling, good in elasticity and good in product quality, the foaming ratio of the product is stable, and the product quality stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of production of PVB foaming products, in particular to a foaming inhibitor and application thereof. Background technique [0002] PVB is also known as polyvinyl butyral ester. During the production process, PVB foam products need to enter the foaming furnace for foaming. It is inevitable to wait for a period of time before entering the foaming furnace. Currently, it is carried out in advance during the waiting stage. Foaming will result in partial consumption of the foaming agent. After entering the foaming furnace, it will either not be able to foam directly, or it will need to be forced to foam by controlling the temperature, resulting in a product that is not delicate and inelastic, affecting product quality, and causing product failure. The expansion ratio is unstable, which affects the stability of product quality. Contents of the invention [0003] For above-mentioned prior art, the purpose of the ...
