Problems solved by technology

[0002] At present, textile rubber products use ordinary bone glue as a reinforcing system, but when using ordinary bone glue, each factory must add water to the ordinary bone glue to heat it into a glue solution, and then add it to the rubber for kneading. This process consumes a lot of energy and is labor-intensive. Large, long production cycle, easy to smell and deteriorate when the glue is not used up
And adding bone glue according to the formula amount in production will easily cause the difference between the actual amount and the formula amount, resulting in fluctuations in product quality
Since ordinary bone glue is water-soluble when added with water, the dispersion of ordinary bone glue in nitrile rubber is poor

Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . The production method of grafted animal glue is characterized in that: bone glue extracted from pig and bovine bones is used as raw material, or the commercial bone glue is swelled in cold water for 2 to 3 hours, heated to dissolve completely after swelling, and then 20 to 20% of the weight of the bone glue is used. 30%, 0.5-1.5%, and 0.05-0.15% are added as auxiliary materials such as glycerin, zinc sulfate, and sodium dithionite respectively, the temperature is kept at 65-70°C, the reaction is stirred for 0.5-1.5 hours, and then freeze-dried.

Embodiment 2

[0010] Embodiment 2: with reference to attached figure 1 . The production method of grafted animal glue is characterized in that: the bone glue extracted from pig and bovine bones is used as raw material, or the commercial bone glue is swelled in cold water for 2 hours, heated to completely dissolve after being completely swollen, and then 20% or 0.5% of the weight of the bone glue is used. % and 0.05% by adding glycerin, zinc sulfate, and sodium dithionite as auxiliary materials respectively, keeping the temperature at 65° C., stirring and reacting for 0.5 hours, and then freeze-drying.

Embodiment 3

[0011] Embodiment 3: with reference to attached figure 1 . The production method of grafted animal glue is characterized in that: bone glue extracted from pig and bovine bones is used as raw material, or commercial bone glue is swelled in cold water for 2 to 3 hours, heated until completely dissolved after fully swelling, and then weighed by 30% of the weight of the bone glue , 1.5%, 0.15% by adding glycerin, zinc sulfate, and sodium dithionite auxiliary materials respectively, keeping the temperature at 70° C., stirring and reacting for 1.5 hours, and then freeze-drying.

Abstract

The invention relates to a method for producing grafting animal glue which is used to improve the quality of textile rubber products. The gone glue extracted from pig or ox bones are taken as raw material, or the commercial bone glue is placed in cold water to swell for 2-3 hours, and heated to to being fully dissolved after full swelling, then, the accessory materials of glycerin, zinc sulfate and sodium hydrosulfite are added respectively pro rata according to the bone-glue weight proportions of 20-30 percent, 0.5-1.5 percent and 0.05-0.15 percent, the temperature is remained at 65-70 DEG C, stirred for reaction for 0.5-1.5 hours, and then frozen and dried.

Description

technical field [0001] The invention relates to a production method of grafted animal glue for improving the quality of textile rubber products, and belongs to the field of production method of modified animal glue. Background technique [0002] At present, textile rubber products use ordinary bone glue as a reinforcing system, but when using ordinary bone glue, each factory must add water to the ordinary bone glue to heat it into a glue solution, and then add it to the rubber for kneading. This process consumes a lot of energy and is labor-intensive. Large, long production cycle, easy to smell and deteriorate when the glue is not used up. And adding bone glue according to the formula amount in production will easily cause the difference between the actual amount and the formula amount, resulting in fluctuations in product quality. Since ordinary bone glue is water-soluble when added with water, the dispersion of ordinary bone glue in nitrile rubber is poor. Contents of t...
