Description
Technical field
The present invention relates to the preparation method of the glass fibre that a kind of hydroxyapatite is modified, belong to the preparing technical field of functional material.
Background technology
Cement and cement-based material are the construction materials that in current architecture production, application amount is maximum, range of application is the widest.Intensity is the important performance indexes of structural material, although cement-based material has the highest comprcssive strength, but in use enbrittle compared with big, tensile strength is relatively low, limit elongation is little, easily produce the problems such as plastic shrinkage cracking, leverage life-span and the serviceability of cement-based material.Fiber is mixed in cement-based material as reinforcing material, the tensile strength of cement-based material, anti-impact force, bending resistance can be effectively improved, control or reduce generation and the extension of cement-based material crackle during solidification and use, stop the infiltration of water, prevent the corrosion of reinforcement component.
Steel fiber reinforced cement composite has the advantage that tensile strength is high, but also has expensive shortcoming, so being difficult to promote.Carbon fiber, its Young's modulus is high, corrosion-resistant, but application focuses primarily upon in high-tech industry, and price is high and yield is little, is unsuitable for large-scale application.In cement-based material, fill a certain amount of alkali-resistant glass fibre can add impact strength and the tensile strength of reinforced concrete, during therefore glass fibre is applied to part building.But fiberglass surfacing is smooth, there is the phenomenon of spike protein gene, and the fiberglass surfacing after wetting agent is modified can be low, is difficult to mix homogeneously in cement, and the cohesiveness not had, therefore glass fibre had to pass through surface modification before being applied in cement-based material.The extra coarse degree improving fiberglass surfacing is to solve glass reinforced concrete glass/glass fiber compound material to develop the key technology faced.
Summary of the invention
For the deficiencies in the prior art, the invention provides the glass fibre preparation method that a kind of hydroxyapatite is modified, the method can increase substantially the surface extra coarse degree of glass fibre, reduces the surface energy of glass fibre.
The preparation method of the glass fibre that a kind of hydroxyapatite is modified, mainly includes dissolving-standing and reacting-washing-drying process, and specific solution is as follows:
(1) calcium hydroxide suspension is prepared
Take 0.1-0.3 g calcium hydroxide to be scattered in bis-water of 200 mL, form white suspension；
(2) preparation 0.01-0.05 mol/L phosphoric acid solution
(3) standing and reacting
A small amount of glass fibre is added in calcium hydroxide suspension prepared by 100 mL, the speed dripped with 30-60 per minute with 3 mL droppers drips the phosphoric acid solution prepared, and produces white flock precipitate, regulation solution ph to 8-8.5, dripping complete, left at room temperature reacts 10-16 hour；
(4) washing is dried
Outwell the upper strata solvent portions without glass fibre after completion of the reaction, with ethanol and secondary water, products therefrom is washed respectively, remove unsupported in the solid particle of fiberglass surfacing；Product after washing being placed in the drying equipment of 50 ~ 70 DEG C drying, obtains the glass fibre that hydroxyapatite is modified, product scanning electron microscope characterizes as shown in Figure 2.
In the present invention, calcium hydroxide described in step (1) is scattered in the method in secondary water is magnetic stirring 20 min or supersound process 20 min.
In the present invention, glass fibre described in step (3) is any one in long fibre, chopped fiber or braided fiber or its multiple combination.
In the present invention, described in step (3), glass fibre consumption is 1-5 g.
In the present invention, described in step (4), drying equipment is baking oven, resistance box or Muffle furnace.
Beneficial effects of the present invention
(1) fiberglass surfacing that the hydroxyapatite prepared is modified is uneven, substantially increases the surface roughness of glass fibre.
(2) standing and reacting process is carried out at room temperature, and reaction condition is gentle, reduces the demand to energy resource consumption, meets the requirement of sustainable development.
(3) preparation process need not reaction under high pressure condition, reaction vessel is required low, meet the production requirement of the glass fibre of the high extra coarse degree of high-volume, it is easy to accomplish commercial production.
