Problems solved by technology

Because the surface of basalt fiber is very smooth and has poor compatibility with other materials, when it is used as a pavement reinforcement material, it is easy to shift with the underlying soil base and cause the risk of cracks on the upper pavement
[0007] Patent CN201010567001.6 discloses a polyester basalt fiber cloth, which is formed by blending basalt fiber and polyester fiber into a non-woven fabric and spraying glue. For spinning geotextiles, since basalt fibers are brittle fibers, during the carding process, the steel needles on the card clothing of the carding machine will cause damage to the fibers, causing the basalt fibers to break and ultimately affecting the use strength of the geotextiles.
[0008] In order to overcome the shortcomings of traditional glass fiber grids such as poor compatibility, poor toughness, need to improve alkali resistance, and low strength of polyester fiber geotextiles, better use of basalt fibers makes the method of producing civil engineering materials more convenient and more environmentally friendly , the invention provides a building material and a preparation method thereof

Abstract

The invention discloses a building material and a preparation method thereof, and relates to the field of new building materials. The method comprises: preparing basalt fiber woven fabric; feeding, opening, mixing and carding the polyester fiber, and peeling to obtain a three-layer polyester fiber web; placing the basalt fiber woven fabric roll on the three-layer polyester fiber Between the first layer and the second layer of the net, a composite structure layer of three layers of polyester fiber mesh and basalt fiber woven fabric is obtained; nine spunlace is used to spunlace the composite structure layer to obtain a grammage of 180-320? g / m2, a monolithic material with a thickness of 0.35-1.2mm; the monolithic material is wound into rolls to obtain building materials. The invention flexibly entangles polyester fibers with pollution-free, low-cost basalt fibers through high-pressure spunlace, which can avoid damage to basalt fibers, and the obtained building materials have good strength, toughness and compatibility, which solves the problem of using The materials prepared by basalt fiber have poor strength, poor toughness and poor compatibility.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a building material and a preparation method thereof. Background technique [0002] The pavement structure of existing highways and urban traffic roads in my country is generally divided into two layers: the lower layer is the soil base layer, and the upper layer is the asphalt concrete protective surface layer, which mainly plays the role of protecting the soil base and making the road surface smooth, so as to meet the traffic requirements of vehicles. need. Usually, the asphalt concrete protective surface of the road we are using has good compatibility with the soil base and high bonding strength. However, when the pavement reaches the design service life requirement or has not yet reached the service life, the pavement protective layer will be damaged due to the use of overloaded trucks. Therefore, it is necessary to repair the damaged pavement, and at the same time take ...
