Abstract

The invention discloses a cement-based material reinforced basalt fiber and a preparation method thereof. The preparation method includes the following steps: (1) a substrate basalt fiber is prepared;(2) the basalt fiber in the step (1) is infiltrated with an infiltration agent, wherein the infiltration agent comprises, by weight, the following components: 0.1%-2% of a coupling agent, 0.5%-10% ofa film forming agent, 0.1%-2% of a lubricant, and 86%-96% of water; and (3) the infiltrated basalt fiber in the step (2) is dried and chopped to obtain the cement-based material reinforced basalt fiber. The preparation method adopts the infiltration agent with low solid content to infiltrate, the basalt fiber is obtained and is utilized as a cement-based material reinforced fiber, the fiber bundling property is reduced, when the basalt fiber is mixed with a cement-based material, the basalt fiber enters various parts of the cement-based material in a form of monofilament, and formation and extension of fine cracks of the cement-based material can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of basalt fiber, in particular to a cement-based material reinforced basalt fiber and a preparation method thereof. Background technique [0002] At present, common cement-based materials reinforce basalt fibers. In order to prevent fluffing and agglomeration during mixing with cement-based materials and reduce the mixing effect, the sizing used usually has a very high solid content, which can cover the fiber surface with a thick layer. The thick film plays a protective role, and at the same time, the fiber bundle is very good. [0003] The disadvantage of this product is that it has a small contact surface with cement-based materials, and the distribution is sparse and uneven. It has no obvious effect on some products that require high resistance to fine cracks. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the invention provides a cement-based material reinforced basalt...
