Abstract
The invention discloses a method for preparing a sheet material adhesive and relates to the field of sheet material production. The method for preparing the sheet material adhesive comprises the steps: (A) adding a protein-containing raw material into water, and stirring uniformly; (B) carrying out ultrasonic treatment on the solution obtained in the step (A); (C) adding sodium dodecylbenzene sulfonate into the solution obtained in the step (B), and stirring; (D) adding boric acid into the solution obtained in the step (C), and stirring; (E) adding hexa-acetamide, a reinforcing agent and an anticorrosive agent into the solution obtained in the step (D), and stirring uniformly, thereby obtaining the sheet material adhesive. According to the method, the sheet material adhesive prepared by the method is used for solving the problems that the existing synthetic resin adhesives release formaldehyde, pollute environment and are harmful to human. The sheet material adhesive is low in cost, high in bonding strength and good in water resistance and corrosion resistance and can cure at normal temperature, and particularly the low-temperature resistance is better than that of other adhesives.
Description
Technical field
The present invention relates to board materials production field, especially a kind of making method of sheet material tackiness agent.
Background technology
The tackiness agent that current production process of plate uses has 90% to be " three-aldehyde glue (three aldehyde refer to phenolic aldehyde, urea aldehyde, melamino-formaldehyde, lower same) ", but " three-aldehyde glue " in use can discharge formaldehyde, and serious harm people are healthy.
So study and use efficient, healthy, cheap tackiness agent, be not only the requirement of human consumer to enterprise, or the environmental regulation of increasingly stringent is to the requirement of enterprise.
Summary of the invention
The invention provides a kind of making method of sheet material tackiness agent, the sheet material tackiness agent that it is made can solve existing adhesive made of synthetic resin Diazolidinyl Urea, contaminate environment and harmful problem.
In order to solve the problem, the technical solution adopted in the present invention is: the making method of this sheet material tackiness agent comprises the following steps:
A, joining 80 ~ 100 weight parts in the water of 400 ~ 700 weight parts containing protein raw material, stir and obtain protein solution;
B, steps A gained protein solution carried out the supersound process 50 ~ 70 minutes that power is 100 ~ 120W, treatment temp is 45 ~ 55 DEG C;
C, add the Sodium dodecylbenzene sulfonate of 0.5 ~ 2.5 weight part to step B gained solution, stir 0.5 ~ 2 hour;
D, add the boric acid of 5 ~ 8 weight parts to step C gained solution, stir 0.5 ~ 3 hour;
E, add the sanitas of the ethanamide in the sixth of the twelve Earthly Branches of 10 ~ 30 weight parts, the toughener of 10 ~ 30 weight parts and 10 ~ 30 weight parts to step D gained solution, stir and get final product;
Described proteinaceous raw material is the mixture of one or more of Zein powder, soybean protein powder, animal globulin powder;
Described toughener is the mixture of one or more in ore powder, diatomite, kaolin, wilkinite, xanthan gum, sodium alginate, hydroxypropyl starch ether, propylene glycol alginate, gelatin, dextrin, pectin, carrageenin, agar, Sudan Gum-arabic or Xylo-Mucine;
Described sanitas is the mixture of one or more of Sorbic Acid, potassium sorbate, phytic acid, methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, propylparaben, ethoxyquin, dehydroacetic acid (DHA), phenylformic acid, Sodium Benzoate, Sodium Propionate, calcium propionate, sodium bisulfite or S-WAT.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, not Diazolidinyl Urea in use procedure of the present invention, safety and environmental protection.
2, raw material sources of the present invention are wide, and cost is low.
3, the ethanamide in the sixth of the twelve Earthly Branches that the present invention adopts has higher reactive behavior, and normal temperature solidified, glued membrane is tough and tensile, shock-resistant, flexibility is good, and oil resistant is wear-resisting, and especially resistance to low temperature is better than other tackiness agent.
4, there is sulfonic group in the Sodium dodecylbenzene sulfonate structure that the present invention adopts, chemical reaction can be there is with the functional group in protein, hydrophobic group alkyl and stupid base have very large steric effect simultaneously, reduce the free energy that non-polar sidechain shifts from hydrophobic interior to water medium, by modified protein, its former hydrophobic side being hidden in inside is shifted externally, interact with the hydrophobic position of Sodium dodecylbenzene sulfonate and form micella group, thus add the hydrophobicity of adhesive layer, improve the water tolerance of tackiness agent.
5, the boric acid that the present invention adopts can discharge hydrogen ion, the crosslinking reaction between carbohydrate can be promoted on the one hand in the modifying process of invention adhesive, the existence of protonic acid can make structure orderly in protein be upset on the other hand, increase the crosslinked probability of tackiness agent and timber functional group, thus the object strengthening bonding strength can be reached, strengthen glueability; By measuring on mechanics machine, butt bonding strength of the present invention is 1.1MPa ~ 1.4 MPa, and wet basis bonding strength is 0.9 MPa ~ 1.2 MPa, is greater than the requirement that GB is greater than 0.7 MPa.
6, antiseptic property of the present invention is good.
