Embodiment 1

[0019] A preparation method of animal hoof horn type surfactant, comprising the following steps:

[0020] (1) Collect hoof horn scraps (powdered, passed through a 20-mesh sieve) from the hoof horn handicraft factory;

[0021] (2) Add 100g of the selected hoof scraps to 1000g of water;

[0022] (3) Add 15g of calcium hydroxide, carry out the hydrolysis reaction at 95°C for 4 hours, and keep stirring during the reaction;

[0023] (4) After the hydrolysis is completed, add dilute hydrochloric acid for acid-base neutralization;

[0024] (5) Remove the solid residue by filtration to obtain the product, and its technical performance as a foaming agent is shown in Table 1.

Embodiment 2

[0026] A preparation method of animal hoof horn type surfactant, comprising the following steps:

[0027] (1) Select the leftovers (powder or silk) of the hoof horn handicraft factory;

[0028] (2) Add 150g of the selected hoof scraps to 1000g of water;

[0029] (3) Add 30g of hydrochloric acid, carry out the hydrolysis reaction at 85°C for 4 hours, and keep stirring during the reaction;

[0030] (4) After the hydrolysis is completed, add sodium hydroxide for acid-base neutralization;

[0031] (5) Remove the solid residue by filtration to obtain the product, and its technical performance as a foaming agent is shown in Table 1.

Embodiment 3

[0033] A preparation method of animal hoof horn type surfactant, comprising the following steps:

[0034] (1) Select the leftovers (powder or silk) of the hoof horn handicraft factory;

[0035] (2) Add 250g of the selected hoof scraps to 1000g of water;

[0036] (3) Add 5g of protease, carry out the hydrolysis reaction at 50°C for 4 hours, and keep stirring during the reaction;

[0037] (4) After the hydrolysis is completed, perform enzyme inactivation treatment;

[0038] (5) Remove the solid residue by filtration to obtain the product, and its technical performance as a foaming agent is shown in Table 1.

[0039] The technical performance contrast that table 1 gained surfactant of the present invention uses as whipping agent

Abstract

The invention relates to a preparation method of an animal toenail type surfactant. The preparation method comprises the following steps of firstly, selecting powdery or filamentary or lancet-shaped toenail materials; secondly, adding selected toenail materials into water according to the weight ratio of 0.1 to 0.8:1; thirdly, adding base, acid or enzyme for performing hydrolysis reaction, and continuously stirring in the reaction process; fourthly, after hydrolysis is finished, if base or acid hydrolysis is generated, adding corresponding acid or base for performing acid-base neutralization, and if enzymolysis is generated, performing corresponding enzyme inactivating treatment; fifthly, filtering to remove a solid remnant to obtain the animal toenail type surfactant. According to the preparation method disclosed by the invention, a hydrolysis product can obtain higher activity and higher foaming rate, and needs lower cost; meanwhile, the problem about pollution caused by wastes is also solved, and further environmental protection is better facilitated.

Description

technical field [0001] The invention belongs to the technical field of biomass processing, and in particular relates to a preparation method of an animal hoof horn-type surfactant. Background technique [0002] Animal protein surfactants are protein actives obtained by hydrolysis of animal hoof horns, hair, blood glue, etc., and can be used as foaming agents, especially in inorganic gelling materials (cement, magnesite, concrete) The foaming industry has broad application prospects. However, the existing production process still has poor raw material treatment effect (due to the toughness of the hoof horn, it is extremely difficult to crush into powder; the hoof horn material is loosened or embrittled by baking or high-temperature and high-pressure steaming, and the particles are large), and the hydrolysis is not good. Thoroughness, low concentration of hydrolyzate, low activity, and low foaming power lead to serious waste of raw materials and high production costs. Conte...
