Description
Technical field:
The invention belongs to building material cement industry, the present invention relates to utilize high-boiling alcohol lignin and hbs lignin derivative thereof technology and prescription as sand-cement slurry or concrete modifying auxiliary agent.
Background technology:
In the past at building material cement, have in the concrete industry and use the precedent of sulfonated lignin as water reducer, but sulfonated lignin are to extract to obtain from traditional papermaking " black liquor ", not only foreign matter content is very high, and great structural modification takes place in the natural lignin in the plant material after the boiling of alkali and sulphite, sulfonated lignin have certain effect as water reducer, but sand-cement slurry or concrete modifying are not produced the superpolymer effect.
Summary of the invention:
The invention solves prior art and from papermaking " black liquor ", extract the above-mentioned defective that sulfonated lignin brought, provide a kind of purity height, complete processing simple, implement easily, and to the preparation of the good hbs lignin derivative-concrete composite material of concrete modified effect.
Technical scheme of the present invention is as follows:
(1) contain the concrete composite material of high-boiling alcohol lignin or derivatives thereof: it includes following ingredients, and the ratio of weight and number of each composition is:
High-boiling alcohol lignin or its derivative 5-80 part,
Mixed solution 10-95 part of epoxy chloropropane or epoxy chloropropane and alcohols,
Cement, sandstone class raw material 5-80 part,
One or more 0.05-5 parts in amine or anhydrides or phenolic or polythiol type or the multicomponent isocyanate type solidifying agent.
(2) preparation technology:
1, earlier the coagulating cement soil composite material is mixed by the needed sand of performance index, pebbles or rubble, cement and water, standby;
2, high-boiling alcohol lignin or its derivative are mixed with the mixed solution of alcohols with epoxy chloropropane or epoxy chloropropane, also add bisphenol A-type or other type of epoxy resin, described other type of epoxy resin is Bisphenol F type, bisphenol S type, Hydrogenated Bisphenol A type or linear phenol aldehyde type, fully stirs to make it to dissolve fully or heat to make it to dissolve fully;
3, the mixing solutions with above-mentioned formation joins in the sand-cement slurry, being about to the mixture of step 1 and the mixed solution of step 2 mixes, fully stirring makes it to mix, and adds in amine or anhydrides or phenolic or polythiol type or the multicomponent isocyanate type solidifying agent one or more;
4, placement makes it to solidify.
Characteristics of the present invention are as follows:
1, the high-boiling alcohol lignin of the present invention's employing under certain temperature, pressure condition, makes lignin dissolution among high boiling alcoholic solvent, makes it separate with Mierocrystalline cellulose.Outside desolventizing, the preparation process of high-boiling alcohol lignin do not add other chemical agents, the high-boiling alcohol lignin purity height that obtains, and ash oontent is than low tens times of traditional sulfonated lignin.
2, because high-boiling alcohol lignin is that the high boiling solvent (hbs) method makes, it has kept the chemically reactive of natural lignin preferably.With the high-boiling alcohol lignin is raw material, under certain conditions, can make the aldehydes of high-boiling alcohol lignin, phenols, or halide derivative, also can form graft product or form mixture, can select the high-boiling alcohol lignin additive of adequate types according to needs to different sand-cement slurry or concrete product modification with other monomers with other macromolecule emulsion cosedimentations.
3, high-boiling alcohol lignin and derivative thereof can improve high-boiling alcohol lignin and derivative thereof can improve sand-cement slurry or concrete product as modified additive toughness as the important source material of coagulating cement soil composite material, folding strength and impervious ability have better modified effect than traditional sulfonated lignin.High-boiling alcohol lignin and derivative thereof are network-like superpolymer, after they and sand-cement slurry or concrete are compound and form crosslinked network structure between the inorganic materials such as sand-cement slurry or concrete, therefore improved the toughness of sand-cement slurry or concrete product, increase sand-cement slurry and have more multi-active base group, generate lignin epoxide resin under the calcium hydroxide effect that when cement concrete forms, produces, inorganic component in lignin epoxide resin and the cement concrete combines, thereby after high-boiling alcohol lignin and derivative thereof and sand-cement slurry or concrete are compound better modified effect is arranged.
4. high-boiling alcohol lignin and derivative thereof can improve the toughness of sand-cement slurry or concrete product as modified additive, its modified effect can be regulated by adding a certain amount of solidifying agent, and solidifying agent mainly is organic amine, anhydrides, phenolic or polythiol class, multicomponent isocyanate class solidifying agent.
5. high-boiling alcohol lignin and derivative thereof the addition in sand-cement slurry or concrete product can be according to the needs and the decision of hbs lignin derivative type characteristic of sand-cement slurry or concrete product performance, generally can be between 5%-80%, its result has improved the toughness of sand-cement slurry or concrete product greatly, impervious ability, compare with other high polymer modified cements, not only complete processing is simple for high-boiling alcohol lignin and derivative-concrete goods thereof, enforcement easily, and can reduce production costs, improve competitiveness of product.
6. high-boiling alcohol lignin and derivative thereof can add the matrix material that an amount of bisphenol type compound or other types Resins, epoxy are compounded to form with high-boiling alcohol lignin and derivative thereof and sand-cement slurry or concrete according to the needs of material design performance at sand-cement slurry or concrete composite material in preparation process.
Embodiment:
(1) contain the concrete composite material of high-boiling alcohol lignin or derivatives thereof: it includes following ingredients, and the ratio of weight and number of each composition is:
