Abstract

The utility model discloses a basalt chopped fiber structure of cement concrete, which relates to building materials, and in particular relates to an improvement technology of basalt chopped fiber structures of cement concrete. A basalt chopped fiber body (1) of cement concrete comprises monofilament chopped fibers (2) and a cement type impregnating agent (3); a layer of cement type impregnating agent (3) is bonded on the surfaces of the monofilament chopped fibers (2); 3-10 monofilament chopped fibers (2) form a bunch which forms the basalt chopped fiber body (1) of cement concrete. According to the basalt chopped fiber structure, the problem that very few fibers are dispersed and aggregated when basalt chopped fibers are used in cement concrete at present is solved.

Description

Cement concrete basalt chopped fiber structure

Technical field

The utility model relates to material of construction, is specifically related to the improvement technology of basalt chopped fiber structure for cement concrete.

Background technology

Basalt continuous fiber because of its there is anti-low temperature, without long-term creep, Heat stability is good, the characteristic such as tensile strength is high, unit elongation is low, can be applied to widely the industries such as industry, agricultural, animal husbandry, automobile, boats and ships, physical culture, environmental protection, chemical industry, military affairs, Aeronautics and Astronautics, decoration, building, highway.

Because basalt continuous fiber has the performance more excellent than glass fibre, as wide in operating temperature range, can be applied in the environment of-260 ℃ ~ 800 ℃, at-60 ℃ ~ 450 ℃; Alkaline resistance properties, acid resistance all will be higher than common glass fibre; Anti-oxidant anti-hydrolytic performance is also well a lot of than glass; Modular ratio glass exceeds 1/3rd left and right, can reach 100Gpa, and glass only has 70 ~ 80Gpa; Tensile strength also can be compared with the glass of high-strength No. two, so basalt continuous fiber has wide market application foreground.

At present, basalt fibre in cement concrete is used, the only a few fiber dispersion conglomeration situation there will be.

Summary of the invention

The utility model provides cement concrete basalt chopped fiber structure, and the utility model has solved current basalt fibre in cement concrete is used, the problem of the only a few fiber dispersion conglomeration there will be.

For addressing the above problem, the utility model adopts following technical scheme: cement concrete basalt chopped fiber structure, forms basalt chopped fiber body 1 for cement concrete by monofilament chopped strand 2 and cement mo(u)ld treating compound 3; Monofilament chopped strand 2 surfaces are stained with one deck cement mo(u)ld treating compound 3.

Advantage of the present utility model: thoroughly solved the problem that basalt fibre disperses conglomeration in cement concrete is used; Fiber surface good film-forming property; Bonding boundling ability is strong; Antistatic property is good; Fiber has better consistency and interfacial chemistry to be combined or absorption property with material; Chopped fibres is avoided too much complications.

Accompanying drawing explanation

Fig. 2 is that the utility model is used view.

Nomenclature in figure: 1, cement concrete basalt chopped fiber body; 2, monofilament chopped strand; 3, cement mo(u)ld treating compound.

Embodiment

With best embodiment, the utility model is described in detail below .

As shown in Figure 1-2, cement concrete basalt chopped fiber structure, forms basalt chopped fiber body 1 for cement concrete by monofilament chopped strand 2 and cement mo(u)ld treating compound 3; Monofilament chopped strand 2 surfaces are stained with one deck cement mo(u)ld treating compound 3.The length of described monofilament chopped strand 2 is 3-12 millimeter.The thickness of described cement mo(u)ld treating compound 3 is 0.2-0.6 millimeter.3-10 bar monofilament chopped strand 2 forms a branch of formation and forms basalt chopped fiber body 1 for cement concrete.

The problem existing for prior art, the utility model improves with basalt fibre in the following areas to cement concrete:

One, adopt treating compound, the effect for the treatment of compound is in the production process of basalt continuous fiber, only have the fiber surface of several microns to apply on hundreds of root monofilament and there is oilness, close-burning material, enable to be bonded to a branch of, reduce wear, fiber can be produced by continous-stable normally, can also change the condition of surface of basalt fibre simultaneously, and can also in matrix material, play the keying action that promotes basalt fibre and the high molecular polymer being enhanced, treating compound can change the slickness on ultimate fibre surface effectively, defect and superficiality that the crisp frangibility of property is disperseed again, characteristic with fortifying fibre.The adjustment for the treatment of compound formula, to meet following requirement: (one) is in fiber surface good film-forming property; (2) bonding boundling ability is strong; (3) antistatic property is good; (4) can make fiber and material have better consistency and interfacial chemistry to be combined or absorption property.

Two, drying course.Fiber moisture for cement concrete requires to reach below 0.1%, and the binding agent in treating compound is after heating and melting, transfers polymerization, crosslinked, film forming to, and precursor performance is improved.Drying course is wanted to meet following requirement: (one) preheating temperature and time; (2) bake out temperature and time; (3) air quantity and wind speed are controlled; (4) humidity of drying shed is controlled; (5) thickness of precursor spinning cake and the setting of arrangement position.

Three, chopped operation.Because the snappiness of basalt fibre is lower, so the operational path of fiber should keep straight line as far as possible, avoid too much complications.The towing roller and should use the material large with frictional coefficient of fiber of cutter, the guiding parts of fiber, should use the material with the little and difficult adhesion of fiber coefficient of friction.Chopped specification of quality: (one) dispersiveness; (2) chopped rate.

By the adjustment to technical parameter, through the test of many times of working-yard, use, make basalt chopped fiber in the result of use of cement concrete, be greatly improved, reached functional quality requirement.

Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all embodiments.And the apparent variation of being amplified out thus or change are still among protection domain of the present utility model.
