Description
Technical field
The invention belongs to fibre modification cement-base composite material technical field, relate to a kind of plant cellulose fiber/water cement-based composite material and preparation method thereof.
Background technology
Cement-based material uses maximum material of construction in the world at present, and it has the advantages that ultimate compression strength is high and bending strength is low, and in order to improve the bending strength of cement material, fiber becomes one of requisite component of modern cement-based material.At present, steel fiber, polypropylene fibre, glass fibre and fibrous magnesium silicate etc. have applied to obtain comparative maturity as the technology of strongthener, but the corrosion of reinforcing bar remains the major cause affecting concrete structure durability, easily there is corrosion problem at crack place in steel fiber, has become a thorny old problem; The need of production phenolic compound of polypropylene-base fiber is as antioxidant, and aminated compounds is as anti-ultraviolet stablizer, and other additive is as fire retardant, and production technique is both not environmentally also uneconomical; Glass fibre has good insulating property and antiultraviolet, anti-static electrification, but glass wool dirt can directly enter lung pipe, causes respiratory tract disease; And the price of these fibers is also relatively costly, add concrete cost.Vegetable fibre, compared with artificial synthetic fiber, has same intensity, but cheap, and wide material sources, environmental friendliness, and has renewable, degradable feature; Especially 20 century 70s start, and after the carcinogenic problem of asbestos is suggested to, make the research of increasing countries and regions to vegetable fibre refinforced cement sill create keen interest.
As the one of vegetable fibre, agricultural crop straw is the natural macromolecular material that nature enriches very much, be a kind of low cost, renewable, degradable natural resource, agriculture production all can produce the agricultural crop straw of billions of tons every year, is but paid attention to and develops for a long time.In China, current most of agricultural crop straw is abandoned as refuse or low-grade fuel burns, and not only wastes valuable biomass resource, and major polluting atmosphere environment.Therefore, the exploitation of agricultural crop straw are the task of top priority, and by agricultural crop straw refinforced cement sill both for the exploitation of stalk resource provide a kind of approach, also meet the strategic choice of material of construction and even economy, environment and social sustainable development simultaneously.
Existing investigative technique shows, the hemicellulose in stalk chemical constitution seriously hinders the heat evolution velocity of cement, and the high alkalinity environment of cement matrix also can destroy the strong conjunction ability between each composition of vegetable fibre thus fall low-fiber intensity simultaneously; Secondly the waxy substance of stalk surface existence, is unfavorable for the gummed of stalk fibre and cement; Above reason greatly limit the application of agricultural crop straw in concrete base building material.In order to improve the restriction that above-mentioned reason is applied agricultural crop straw, traditional method is by stalk fibre before adding cement matrix, adopts suitable mode process to promote its alkali resistant ability.As processed stalk fibre by NaOH solution, its objective is the wax layer destroying stalk surface, make by dipping by lye a large amount of extract Precipitations in fiber, cement being had to slow setting or anticoagulation simultaneously, thus the interfacial adhesion of fortifying fibre and cement matrix, improve the mechanical property (Fan Hua of cement-based material, Sheng Li. the performance test research of straw fiber cement sill, Agricultural University Of Anhui's journal 2011; 38:643-646.).Above measure can increase cohesive force between itself and cement matrix by destroying fiber surface structure, thus improves the anti-bending strength of matrix material to a certain extent, but does not have too large effect for the improvement of fiber self-strength.Compared with above technology, stalk fibre cellulose fiber has following advantage as the strongthener of cement matrix.First, consider from the strength characteristics of fiber self, cellulosic fibre has higher intensity and plays mould compared with stalk fibre former state.(A.K.Bledzki, J.Gassan.Composites reinforced with cellulose based fibres.Prog.Polym.Sci.1999 according to the literature; 24:221-274), the Young's modulus of certain vegetable fibre former state is 10GPa, and its Young's modulus of cellulosic fibre that vegetable fibre extracts thus can reach more than 40GPa.Secondly, with regard to the interfacial effect of Fiber In Composite Material and cement, the cellulosic fibre of single structure and cement have better interface structure adjustability, thus are conducive to the cohesive force between raising component.3rd, adding of stalk fibre cellulose fiber, the composition such as hemicellulose and xylogen in stalk stock blend can be avoided to degrade in cement matrix and the fibrous texture that causes destroys, affect the strength of materials.
The disclosed quick-fried pretreatment technology of ultrasonic assistant vapour extracted for crop branch fiber element of Chinese patent CN102230284A (ZL 201110116073.3), with the xylogen environmental protection abstraction technique that patent CN101798769A (ZL 201010141040.X) reports, propose a set of Technology extracted for crop branch fiber element, effectively removes the complex structure such as hemicellulose and xylogen in agricultural crop straw, the composition of less stable, the stalk cellulose obtained through this Technology has intensity far above former stalk fibre and toughness.
Summary of the invention
In view of the defect in prior art existing for stalk refinforced cement based composites, the cellulosic fibre that the present invention utilizes stalk to extract, as the strongthener of cement-based material, provides a kind of formula, technique and preparation method by stalk cellulose fiber reinforced cement-based composite material.Be intended to utilize stalk fibre cellulose fiber to increase anti-bending strength and the toughness of cement-based material, and dewatered by vacuum filtration for the strong feature of plant cellulose fibrous absorbent and a kind of low density of explained hereafter, high tenacity, the high-strength matrix material-stalk cellulose fiber cement composites such as pressurization.
The object of the invention is by following means realize.
