Problems solved by technology

[0004] Yet for gel material, boric acid, sodium borate and sodium perborate etc. are all commonly used crosslinking agent materials for preparing gel material, if the consumption of boron is little, will directly affect the crosslinking degree of gel material, thus Affect the viscosity of the gel material, and even make the prepared substance not a gel material at all
In addition, the high temperature resistance of current gel materials is also poor

preparation example Construction

[0032] A method for preparing a gel material in an embodiment includes the following steps: mixing raw materials to obtain a gel material. Wherein, in terms of mass percentage, the raw materials include: 70.2%-99.48% of water, 0.5%-28% of thickener, 0.02%-0.6% of aluminate and 0-1.2% of boron source.

[0033] Wherein, the thickener is at least one selected from galactomannan, konjac glucomannan, polyvinyl alcohol, derivatives of galactomannan and derivatives of konjac glucomannan.

[0034] Specifically, the derivative of galactomannan is selected from the group consisting of hydroxyethyl galactomannan, hydroxypropyl galactomannan, carboxymethyl galactomannan, carboxymethyl hydroxyethyl galactomannan At least one of sugar and carboxymethylhydroxypropyl galactomannan.

[0035] Specifically, the derivatives of konjac glucomannan are selected from the group consisting of hydroxyethyl konjac glucomannan, hydroxypropyl konjac glucomannan, carboxymethyl konjac glucomannan, carboxyme...

Embodiment 1～18

[0050] The preparation process of the gel material of embodiment 1~18 is as follows:

[0051] (1) Weigh each component according to Table 1.

[0052] (2) Dissolving the thickener, aluminate and boron source in water respectively to obtain an aqueous solution of the thickener, an aqueous solution of the aluminate and an aqueous solution of the boron source; adding the aqueous solution of the aluminate to the aqueous solution of the thickener , then add the aqueous solution of boron source, stir and mix for t minutes, and obtain the gel material.

Abstract

The invention relates to a gel material and its preparation method, plastic product and application. In terms of mass percentage, the raw materials for preparing the gel material include: 70.2% to 99.48% of water, 0.5% to 28% of thickener, 0.02% to 0.6% of aluminate and 0 to 1.2% of boron source The thickener is selected from at least one of galactomannan, konjac glucomannan, polyvinyl alcohol, derivatives of galactomannan and derivatives of konjac glucomannan, and the boron source is selected from boric acid and at least one of borates. The above-mentioned gel material not only has less boron content, but also has a suitable viscosity, and also has better high temperature resistance.

Description

technical field [0001] The invention relates to a gel material and its preparation method, plastic product and application. Background technique [0002] In Europe, the Chemical Registration, Evaluation, Authorization and Restriction Regulations, referred to as REACH Regulations (full name: Registration, Evaluation, Authorization and Restriction of Chemicals), which began to be fully implemented on June 1, 2007, has successively released a series of highly concerned chemicals. Referred to as SVHC substances. According to the requirements of REACH regulations, when the SVHC content in the product exceeds 0.1%, and the export volume of the enterprise exceeds 1 ton / year (1t / year), the enterprise needs to report to ECHA (European Chemicals Agency). Boric acid and sodium borate are included in the third batch of SVHC (announced on June 8, 2010), and sodium perborate and sodium metaborate are included in the eleventh batch of SVHC (announced on June 16, 2014). published). [00...
