Embodiment Construction
[0012] A kind of basalt grid cloth, which is made of basalt fiber woven fabric, soaked in acrylic acid polymer latex, coated with leno weaving, and then treated with alkali-resistant penetrating agent and high-temperature heat-setting treatment of reinforcing agent. into, the specific process steps are as follows:
[0013] (1) Soak the basalt fiber woven fabric into the acrylic acid polymer emulsion in the bubbling mixing tank, the soaking time is controlled at 20-60 minutes, the temperature is controlled above 30°C, and the gas is bubbling and mixed at the same time;
[0014] (2) After the basalt fiber is taken out and dried, the basalt fiber is twisted according to the leno structure to form a warp layer and a weft layer;
[0015] (3) hot pressing at high temperature, so that the warp yarn layer and the weft yarn layer are hot-pressed and welded to obtain the basalt mesh cloth;
[0016] (4) Soak the basalt mesh cloth in the alkali-resistant penetrating agent, then soak it i...

Abstract
The invention discloses a production process of basalt gridding cloth. The basalt gridding cloth is prepared by adopting fiber woven fabrics of basalt as base materials, soaking in acrylic polymer emulsion for coating, carrying out twist-weaving of gauze weaves, and then carrying out alkali-resistant treatment with an alkali-resistant penetrating agent and high-temperature heat setting treatment with an enhancing agent. The production process is characterized in that the fiber woven fabrics of the basalt are adopted as base materials and are soaked by the acrylic polymer emulsion, so that the alkali resistance, the flexibility and the tensile strength of the warp-direction and weft-direction heights are good; and then the alkali-resistant treatment with the alkali-resistant penetrating agent and high-temperature heat setting treatment with the enhancing agent are carried out, and finally, by amino silicon oil, the handfeel and the flexibility of a product are greatly improved. The basalt gridding cloth is good in chemical stability, resists alkali, acid, water, cement erosion and other chemical corrosion, is strong in bonding property with resin, is easily dissolved in styrene and the like, is high in strength and modulus and light in weight, is good in size stability, is stiff and flat, is not easily shrunk and deformed, is excellent in positioning performance and better in impact resistance, is anti-mildew and insect-resistant, and is fireproof, heat-insulating, sound-insulating and insulated.
