Problems solved by technology

When it is applied to the production of basalt fiber chopped spun yarn below 7.5 microns, its folding and abrasion resistance cannot meet the requirements of its post-processing needle punching, which affects its product performance. So far, for single fiber diameter 7.5 There is still no special pretreatment enhanced sizing agent for the production of basalt fiber chopped spun yarn below micron

Abstract

The invention relates to a pre-processing reinforced type impregnating agent for a basalt fiber chopped spun yarn and a preparation method of the pre-processing reinforced type impregnating agent and belongs to the technical field of the impregnating agent. The pre-processing reinforced type impregnating agent comprises the following components by weight percent: 2-4% of water-soluble epoxy resins, 2-4% of water-soluble polyurethanes, 0.5-1% of organic silicon latexes, 0-0.1% of cation surface active agents, 0.5-1% of antistatic agents, 0.2-0.5% of organic silane coupling agents, 0.1-0.2% of pH adjusting agents and the balance water. The pre-processing reinforced type impregnating agent and the preparation method provided by the invention are simple in technology and are suitable for the production of the basalt fiber chopped spun yarn with a single fiber diameter of 3.5-7.5 microns. The basalt fiber chopped spun yarn produced by utilizing the pre-processing reinforced type impregnating agent is high in strength and excellent in flexibility; a produced high-temperature acupuncture filter felt is free from being subjected to heat treatment; silicon oil and tetrafluoro coatings can be directly coated; energy source is saved; environmental pollution is reduced; and the pre-processing reinforced type impregnating agent is excellently combined with an interface of a produced product substrate and is high in strength.

Description

technical field [0001] The invention relates to a pretreatment enhanced sizing agent for basalt fiber chopped spun yarn and a preparation method thereof, belonging to the technical field of sizing agents. Background technique [0002] Basalt fiber chopped spun yarn is a kind of high-temperature-resistant chopped strand fiber for making high-temperature needle-punched filter felt. The chopped strand is used to make the surface layer of high-temperature filter needle-punched felt, and is interlinked on the surface of the base fabric by non-woven needle-punched technology. , combined with the base cloth and intertwined to form a three-dimensional structure with micropores, which plays a role in blocking dust. The high-temperature needle-punched filter felt made of basalt fiber yarn does not require heat treatment, and can be directly coated with silicone oil and PTFE coating, which saves energy and reduces environmental pollution. The interface with the base material of the pr...
