Embodiment Construction

[0014] A kind of embodiment of the preparation method of basalt fiber stick for concrete Figure 1~3 Shown:

[0015] The preparation method uses a preparation device to prepare basalt fiber sticks. The preparation device includes an encapsulating device 3, a conveying device 6, a reinforced structure forming device 8 and a fiber bundle cutting device 11 arranged in sequence along the conveying direction of the basalt fiber bundle.

[0016] Wherein the gluing device belongs to the prior art, the more common one is a cable gluing machine, which includes a gluing device seat 5, on which the basalt fiber bundle 1 is provided with a fiber bundle passage 2 and a fiber bundle passage 3 There is a glue injection channel on the periphery, and the glue injection channel communicates with the fiber bundle channel. When in use, the basalt fiber bundle passes through the fiber bundle channel, and the melted glue 4 enters the fiber bundle channel through the glue injection channel and wraps...

Abstract

The invention relates to a preparation method of a basalt fiber stick for concrete. The preparation method comprises the following steps: firstly, the outer periphery of a basalt fiber bundle is wrapped with a wrapping layer through a wrapping device, wherein the wrapping layer is made of a plastic material with a melting temperature of 230 DEG C or above; secondly, the basalt fiber bundle is conveyed downstream, and the wrapping layer at a temperature of 170-190 DEG C is extruded by a pair of cold-pressing forming rollers of a reinforcing structure forming device, so that a reinforcing structure is formed on the outer periphery of the wrapping layer, and the reinforcing structure is a convex structure or a concave structure. The reinforcing structure forming device comprises the pair of cold-pressing forming rollers, and outer roller surfaces of the cold-pressing forming rollers are provided with forming hollows or forming protrusions for extruding the wrapping layer. The invention solves the technical problem of insufficient connection force between basalt fibers and concrete in the prior art.

Description

technical field [0001] The invention relates to a method for preparing a basalt fiber stick for concrete in the field of concrete construction. Background technique [0002] In the field of road construction and construction, concrete is an essential engineering material, but the workability, crack resistance and corrosion resistance of concrete materials have always plagued the engineering field. The biggest defect of concrete itself is that its tensile strength is low, and it is easily damaged under impact load. [0003] This situation can be improved by adding fibers to concrete, as disclosed in Chinese patent CN109369050A "chopped basalt fiber bundles for strengthening cement concrete and its preparation method", the basalt fiber bundles are dipped in glue, and then cut to form certain Length of chopped fiber bundles, by mixing chopped fiber bundles in concrete to increase the tensile strength and crack resistance of concrete. The problem in the prior art is that the e...
