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
The invention belongs to biomass processing technical field, be specifically related to a kind of preparation method of animal hoof angle-style tensio-active agent.
Background technology
Animal proteinum type tensio-active agent be with animal hoof and foot, hair, blood glue etc. for raw material be hydrolyzed after the protein-active thing of gained, can be used as whipping agent to use, especially have a wide range of applications in inorganic coagulation material (cement, magnesite, the concrete) industry that foams.But existing production technique also exists Feedstock treating poor effect, and (because hoof tips is tough and tensile, extremely difficulty is ground into powder; With baking or the mode that steams of High Temperature High Pressure is loose or brittle hoof tips material, and particle is large), hydrolysis not thoroughly, hydrolysate concentration is low, activity is not high, foaming power is low problem, cause wastage of material serious, production cost is high.
Summary of the invention
For the problems referred to above, the invention provides a kind of preparation method of animal hoof angle-style tensio-active agent, hydrolysate activity can be made higher, blebbing amount is larger, and cost is lower, also solves the pollution problem of waste material simultaneously, is more conducive to environment protection.
For solving the problem, the present invention is achieved through the following technical solutions:
Design a kind of preparation method of animal hoof angle-style tensio-active agent, comprise the following steps:
(1) the hoof tips material (available sources of this hoof tips material: the 1. tankage can collecting hoof tips arts & crafts products factory of powdery, thread or willow leaf shape is chosen; 2. can be pulverized further by hoof and horn grain with pulverizer is powdery);
(2) be added to the water by selected hoof tips material, the two weight ratio is 0.1 ~ 0.8:1, preferably 0.1 ~ 0.25:1;
(3) add alkali or acid, be hydrolyzed reaction 3 ~ 8h under 70 ~ 110 DEG C of (preferably 80 ~ 110 DEG C) conditions, or add enzyme (preferred protease), in 40 ~ 80 DEG C of Water Under solution reaction 1 ~ 10h, constantly stirs in reaction process;
Preferably adding calcium hydroxide (it is pure that production practice show to adopt calcium hydroxide to be hydrolyzed the finished product made, and extension rate is high, and blebbing amount is large) in above-mentioned steps (3) to be hydrolyzed, is 0.6 ~ 10% of water weight by its amount;
(4) after being hydrolyzed, alkali or acid hydrolysis in this way, then add acid accordingly or alkali carries out acid-base neutralisation, and enzymolysis in this way then carries out corresponding enzyme-deactivating process;
(5) filter (by plate-and-frame filter press or strainer) and remove solid excess, to obtain final product.
After adding alkali or acid or enzyme in step (3), hydrolysis midway secondary or repeatedly add hoof tips material, its total add-on is 0.02 ~ 0.6 times of add-on in step (2), to promote that reactant generates, effectively improves product concentration.
In described step (2), after in proportion selected hoof tips material can being added to the water, be heated to boiling, after boiling 1 ~ 5h, carry out follow-up hydrolysis reaction again, practical studies shows, so not only can accelerate the process of sequential hydrolysis reaction, enhance productivity, but also greatly can improve the concentration of hydrolysate.
In prior art about the treatment process of animal hoof and foot raw material be: the mode that (because of hoof tips raw material extreme hardness) will first be steamed by baking or High Temperature High Pressure is loosened or brittle hoof tips material, then is ground into the hoof and horn grain of corn grain size.Contriver studies discovery in production practice, and because in the prior art, the granularity of hoof tips raw material is excessive, cause hydrolysis not thorough, raw material availability is low, and finished product concentration is on the low side; On the other hand, baking or pyroprocessing easily make hoof tips protein denaturation, have had influence on activity and the production concentration thereof of hydrolysate greatly.
The present invention has actively useful technique effect:
Overcome traditional technology prejudice; adopt without loose or brittle hoof tips material, and adopt granularity or the thinner powdery of diameter or wire stock, optimize hydrolysis reaction condition simultaneously; more be conducive to hydrolysis reaction; make hydrolysate activity higher, blebbing amount is larger, reduces cost; because present invention process directly can use the hoof tips tankage of hoof tips arts & crafts products factory; thus production cost can be made lower, also solve the pollution problem of these waste materials simultaneously, be more conducive to environment protection.
