Abstract
The invention discloses an adhesive with high stability. The adhesive is prepared from the following components in parts by weight: 100 parts of modified starch, 0.2-0.5 part of propolis missible oil, 2-5 parts of citric acid, 3-6 parts of cane sugar, 1-3 parts of sodium stearate, 0.8-2 parts of magnesium pyroborate whisker, 1.5-2.5 parts of sodium sulfite, 0.05-0.1 part of tributyl phosphate and 5-9 parts of nanometer SiO2 sol. According to the natural adhesive provided by the invention, through modification on starch by alkaloid, under the mutual blending action of the magnesium pyroborate whisker, the SiO2 sol and the propolis missible oil, the viscosity, stability and durability of the adhesive are greatly improved, disadvantageous effects brought by borax in the prior art can be overcome, and the original viscosity is not influenced, and is even improved.
Description
Technical field
The present invention relates to a kind of sizing agent, be specifically related to good sizing agent of a kind of stability and preparation method thereof.
Background technology
Sizing agent (adhesive): sticking and interiorly poly-ly waiting effect by interface, the natural or synthesis that two or more product or material can be made to link together, an organic or inorganic class material.It is one of material commonly used in modern industry.
Sizing agent is divided into natural glue and synthetic adhesive by Material synthesis.Synthetic adhesive use range is wide, and gluing performance is strong, but it can produce objectionable impurities, not easily degrades, contaminate environment; Natural glue raw material sources enriches, environmentally safe, the advantages such as applying glue is convenient, easy to be recycled, but its viscosity is on the low side, mobility large, and sizing agent quality is very unstable.By the linking agent of borax as sizing agent in prior art, it requires very strict to consumption, does not very fewly reach cross-linking effect, affect the ability of its seasoning, too much, can cause glue-line embrittlement thus cause the phenomenon of coming unstuck, existing business men very demand needs a kind of substitute products.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides good sizing agent of a kind of stability and preparation method thereof.
Technical scheme: for achieving the above object, the sizing agent that a kind of stability provided by the invention is good, its compositions in weight percentage consists of the following composition:

Preferably, described treated starch is modified dextrins.
The preparation method of the sizing agent that above-mentioned stability is good, the preparation process of described sizing agent is:
The preparation of S1 treated starch
S1.1 get starch and concentrated acid mixing, then add the vinealeucoblastine(VLB) aqueous solution, mix after can obtain modified dextrins through 120 ~ 130 DEG C of heating, for subsequent use; The weight ratio of described starch, concentrated acid, the vinealeucoblastine(VLB) aqueous solution is 100:(0.2 ~ 0.6): (100 ~ 150);
The preparation of S2 sizing agent
S2.1 takes corresponding feed composition by weight;
S2.2 is even at 45 ~ 50 DEG C of heating mixed dissolutions by modified dextrins, nanosized SiO_2 colloidal sol and propolis missible oil, then add magnesium borate crystal whisker, citric acid, sucrose, sodium stearate, S-WAT, tributyl phosphate again, be heated to 60 DEG C and stir and can be prepared into sizing agent.
Preferably, described concentrated acid is one in concentrated nitric acid or concentrated hydrochloric acid or two kinds.
Preferably, the concentration of the described vinealeucoblastine(VLB) aqueous solution is 0.05 ~ 0.1%.
Beneficial effect: natural glue provided by the invention has the following advantages in terms of existing technologies:
1) natural glue provided by the invention is by the modification of alkaloid to starch, under magnesium borate crystal whisker, SiO2 colloidal sol and propolis missible oil mutually blending effect, substantially increase the viscosity of gluing, stability and persistence, and overcome the detrimental action brought by borax in prior art, but do not affect its original viscosity, strengthen even to some extent.
2) instant invention overcomes in conventional synthesis sizing agent to react in heating environment and discharge objectionable impurities further, particularly easily heat the material etc. of volatilization containing formaldehyde etc., to environment and the larger harm of staff's generation of surrounding.
3) production cost of the present invention is low, by the effect not easily gel of propolis missible oil, facilitates long-time storage.
