Description
Technical Field
The invention relates to the field of earthen site protection engineering and civil engineering, in particular to a glutinous rice paste-bone glue composite gel material, a preparation method and application thereof.
Background
Ancient buildings are becoming extinct at an alarming rate due to natural efflorescence and artificial destruction, and industrial development and urbanization bring a large amount of chemical byproducts. With the responsibility of ancient architecture restoration to the whole society and the increasingly urgent social requirements of environment-friendly and environment-friendly ancient architectures, an environment-friendly ancient architecture cultural relic reinforced cementitious material is needed. Glutinous rice paste and bone glue are all intelligent crystals left in the historical long river of China, and no volatile organic solvent escapes in the using process.
At present, the research on environment-friendly gel materials is still in need of development.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art.
The present invention has been completed based on the following findings of the inventors:
the inventor finds that the preparation of the pure glutinous rice pulp does not involve high-molecular polymerization reaction, but the strength of the pure glutinous rice pulp is mainly derived from inorganic reaction which can occur when the glutinous rice pulp and the pseudo-ginseng ash are mixed and then contact with air in subsequent treatment, and stress enhancement points such as calcium carbonate, ettringite and the like which can increase the body strength are generated. Although such a blend system can improve the mechanical strength of the matrix, it does not exhibit the desired effects of water resistance and freeze-thaw cycle resistance.
The inventor further researches and discovers that the bone glue as a high molecular material of amino acids has remarkable advantages in enhancing and improving the freezing resistance. Therefore, in the glutinous rice slurry added with the bone glue, the carboxyl of the bone glue molecules and the hydroxyl of the glutinous rice molecules can generate esterification reaction, so that the strength and the durability of the composite gel material can be improved; and the amino group of the bone glue molecule can destroy the hydrogen bond function among the bone glue molecules under the substitution effect of the modifier epichlorohydrin, so that the freezing point of the composite gel material is reduced, and the composite gel material still keeps liquid state at normal temperature. The compounded glutinous rice pulp-bone glue composite gel material is non-toxic and harmless, is in a liquid state at normal temperature, has high mechanical strength and obviously improves the durability; and the combination of the two substances can also solve the problems of low mechanical strength and weak durability of the single glutinous rice paste.
In view of the above, an object of the present invention is to provide a method for preparing a glutinous rice slurry-bone glue composite gel material with high mechanical strength, high durability, environmental friendliness or energy saving.
In a first aspect of the present invention, the present invention provides a method for preparing a glutinous rice slurry-bone glue composite gel material.
According to an embodiment of the invention, the method comprises: (1) mixing glutinous rice, water, alum and sodium hydroxide to obtain glutinous rice pulp; (2) and contacting the glutinous rice pulp, the bone glue, the sodium hydroxide aqueous solution, the epichlorohydrin and the hydrochloric acid to obtain the glutinous rice pulp-bone glue composite gel material.
The invention has the advantages that the preparation method provided by the embodiment of the invention can be used for preparing the composite gel material with high mechanical property, high durability or good frost resistance, the method is energy-saving, low in processing degree and environment-friendly, the durability of the composite gel material is improved by compounding the glutinous rice pulp and the bone glue, and the liquid state at normal temperature is beneficial to the simplicity of operations such as coating, mechanical sizing and the like.
In addition, the preparation method according to the above embodiment of the present invention may further have the following additional technical features:
according to the embodiment of the invention, in the step (1), the weight ratio of the glutinous rice, the water, the alum and the sodium hydroxide is (10-15): (90-110): (0.4-0.8): (0.1 to 0.3); and the mixing is carried out at a temperature of 60-90 ℃, and the mixing time is 1-4 hours. The inventor researches and discovers that the glutinous rice pulp has wide sources of raw materials for preparing the glutinous rice pulp and low cost, and the weight of the added alum and the sodium hydroxide aqueous solution can be finely adjusted according to the proportion of the glutinous rice and the water; the mixing effect is optimal when the temperature is 60-90 ℃, the starch in the sticky rice cannot be gelatinized and cannot be dissolved in water when the temperature is lower than 60 ℃, and the starch in the sticky rice starts to be thermally decomposed when the temperature is higher than 90 ℃; the mixing time is too short or too long, which is not beneficial to the gelatinization effect of the glutinous rice pulp, so that the next chemical reaction can be influenced.
Therefore, the preparation method of the glutinous rice paste is simple and convenient, mild in condition and short in reaction time, and the glutinous rice is gelatinized by the alum and the sodium hydroxide aqueous solution to completely destroy all glutinous rice micelle molecules, so that the solubility and the dispersibility of starch single molecules in the glutinous rice paste in the aqueous solution are improved, and the glutinous rice paste which is beneficial to further carrying out chemical reaction with bone glue is obtained.
According to the embodiment of the invention, the step (2) is specifically as follows: adding bone glue into the glutinous rice pulp for heating and dissolving, adding a sodium hydroxide aqueous solution for degradation, adding epichlorohydrin for crosslinking, and adding hydrochloric acid for esterification to obtain a glutinous rice pulp-bone glue composite gel material; or adding the bone glue into a sodium hydroxide aqueous solution for degradation, adding epichlorohydrin for crosslinking, adding the modified bone glue into the glutinous rice pulp for heating and dissolving, and adding hydrochloric acid for esterification, so as to obtain the glutinous rice pulp-bone glue composite gel material.
The inventor researches and discovers that the terminal amino groups and the terminal carboxyl groups among the bone glue molecules can be mutually associated to form a reticular gel. Therefore, it is necessary to break the gel state of the molecules of the bone glue at normal temperature by heating and adding an alkalizing agent, i.e. an aqueous solution of sodium hydroxide, and to destroy the association between the molecules to release the single molecules of the bone glue. Furthermore, epichlorohydrin is added to perform graft copolymerization with the terminal amino group of the single bone glue molecule to form a modified bone glue molecule with a linear structure, so that the length of the bone glue molecule chain is increased, and the tendency of mutual association among the bone glue molecule chains is reduced. At this time, 1v/v% hydrochloric acid of an esterification catalyst was added to promote an esterification reaction between the terminal carboxyl groups of the modified bone glue molecules and the hydroxyl groups of the single molecules of the glutinous rice starch, thereby obtaining a composite solution containing the glutinous rice pulp-bone glue composite gel material. And finally, cooling the composite solution to normal temperature and filtering to obtain the glutinous rice pulp-bone glue composite gel material. The inventor also finds that the composite gel material with good performance can be obtained by degrading and crosslinking the bone glue in advance and then adding the modified bone glue into the glutinous rice pulp for esterification and composite reaction.
Therefore, the preparation method provided by the embodiment of the invention can be used for preparing the composite gel material with high mechanical property, high durability or good frost resistance, the method is energy-saving, low in processing degree and environment-friendly, the durability of the composite gel material is improved by compounding the glutinous rice pulp and the bone glue, and the liquid state at normal temperature is beneficial to the simplicity of operations such as coating, mechanical sizing and the like.
According to an embodiment of the present invention, in the step (2), the bone glue is used in an amount of 25 parts by weight, and the glutinous rice slurry is used in an amount of 100 to 150 parts by weight. The inventor finds that the proper weight ratio of the bone glue to the glutinous rice pulp is 1: 4-1: 6, too little bone glue is not enough to be completely esterified with starch in the glutinous rice pulp, and too much bone glue can reduce the mechanical property, durability or freezing resistance of the composite gel material. Therefore, by adopting the preparation method provided by the embodiment of the invention, the composite gel material with higher mechanical property, higher durability or better freezing resistance can be prepared by the bone glue and the glutinous rice pulp in a proper weight ratio.
According to an embodiment of the present invention, in step (2), the amount of the aqueous sodium hydroxide solution is 10 parts by weight, the amount of epichlorohydrin is 2 parts by weight, and the amount of hydrochloric acid is 4 parts by weight; wherein the concentration of the sodium hydroxide aqueous solution is 20w/w%, and the concentration of the hydrochloric acid is 1 v/v%. Therefore, by adopting the preparation method provided by the embodiment of the invention, the bone glue is degraded and modified by the sodium hydroxide aqueous solution with specific concentration and the epichlorohydrin, the modified bone glue molecules and starch monomolecular in the glutinous rice paste are subjected to esterification reaction fully under the specific hydrochloric acid concentration, and the glutinous rice paste-bone glue composite gel material with high mechanical property, high durability or high freezing resistance can be formed.
According to the embodiment of the invention, in the step (2), the heating and dissolving are carried out at a temperature of 60-80 ℃, the reaction time of the degradation is 0.5-2 hours, and the heat preservation time of the crosslinking is 0.5-2 hours. The inventor finds that the bone glue has the best dissolution effect at the temperature of 60-90 ℃, so that the dispersibility of the glutinous rice pulp can be maintained, and the release of single molecules of the bone glue can be promoted; the degradation reaction time needs to be 0.5-2 hours, if the reaction time is too short, the bone glue gel is not completely destroyed, and if the reaction time is too long, the degradation of bone glue single molecules is promoted; and the crosslinking heat preservation time is 0.5-2 hours, so that the terminal amino groups of the single molecules of the bone glue are grafted and modified by the epichlorohydrin molecules.
Therefore, by adopting the preparation method provided by the embodiment of the invention, through full degradation, modification and esterification, the glutinous rice pulp-bone glue composite gel material with high mechanical property, high durability or high freezing resistance can be formed, and the method is energy-saving, low in processing degree and environment-friendly.

Therefore, by adopting the preparation method provided by the embodiment of the invention, the glutinous rice paste-bone glue composite gel material with higher purity can be prepared, so that the composite gel material with higher mechanical property, higher durability or better freezing resistance can be obtained.
In a second aspect of the present invention, the present invention provides a method for preparing a glutinous rice pulp-bone glue composite gel material.
According to an embodiment of the invention, the method comprises: (1) mixing 11 parts by weight of glutinous rice with 100 parts by weight of water, adding 0.4 part by weight of alum and 0.2 part by weight of sodium hydroxide, and reacting at 90 ℃ for 1 hour to obtain glutinous rice pulp; (2) adding 25 parts by weight of bone glue into 100 parts by weight of the glutinous rice pulp for dissolving, heating to 80 ℃, adding 10 parts by weight of 20w/w% sodium hydroxide aqueous solution for degradation, reacting for 0.5 hour, adding 2 parts by weight of epichlorohydrin for crosslinking, preserving heat for 1.5 hours, adding 4 parts by weight of 1v/v% hydrochloric acid for esterification, and obtaining a composite solution; (3) and cooling and filtering the composite solution to obtain the glutinous rice pulp-bone glue composite gel material.
