Problems solved by technology

[0005] But the prior art also has the following problems: 1, paraffin wax and starch in the existing E glass fiber sizing technology, the paraffin and starch in the textile type sizing agent can hinder the combination of fiber and organic resin, so use paraffin wax, starch type textile sizing agent The woven glass fiber cloth must be hot cleaned to remove the sizing coating before it can be used, and it is not suitable for the production of reinforced basalt fiber
2. The sizing agent published in the invention patent with the application number CN201210401128 has good effect on basalt fiber drawing and reinforced thermoplastic composite materials, but its spinnability is poor and cannot meet the requirements of weaving fiber cloth, nor is it suitable for thermosetting phenolic epoxy resin composite material

Embodiment 1

[0034] An epoxy-type sizing agent for basalt fiber, which consists of the following components in terms of weight percentage:

[0035] Epoxy emulsion film former 5.0~8.0%

[0036] Lubricant 0.1~1%

[0037] Binder 0.5~1.5%

[0038] Plasticizer 0.5~1.5%

[0039] Antistatic agent 0.2~1.0%

[0040] Coupling agent 0.5~1.0%

[0041] Soft water balance;

[0042] Described epoxy emulsion film-forming agent is EPO-106, and its characteristic is to use the water-soluble emulsion of about 50% content that the trade mark is that E-51 bisphenol A type epoxy resin is made, purchased from Baling Petrochemical Company; Epoxy emulsions with an epoxy value less than 0.44, such as E-20, cannot be used in this formulation, because the hardness after film formation is too high and the flexibility is poor, which is not conducive to improving the bending resistance of basalt fibers.

[0043] The lubricant used was an imidazoline lubricant with a brand name of YG-203, which was purchased from X...

[0058] Antistatic agent 0.2%;

[0059] Coupling agent 0.5%;

[0060] Soft water balance.

[0061] The epoxy emulsion film-forming agent is EPO-106, and the epoxy value is greater than 0.44.

[0062] What described lubricant selects for use is the imidazoline lubricant that the trade mark is YG-203.

[0063] What described binder selects is the water-soluble epoxy resin that the trade mark is 801.

[0064] The plasticizer used is polyethylene glycol with a brand name of PEG4000 and a molecular weight of 3500-4500.

[0065] What described antistatic agent selects for use is inorganic lithium nitrate.

[0066] Described coupling agent selects the coupling agent of American Dow Corning Company trade mark as Z-6132.

Abstract

The invention discloses a special epoxy impregnating compound for a basalt fiber and a preparation method of the special epoxy impregnating compound. The special epoxy impregnating compound for the basalt fiber is prepared from the following components in percentage by weight: 5.0%-8.0% of an epoxy latex film-forming agent, 0.1%-1% of a lubricant, 0.5%-1.5% of binder, 0.5%-1.5% of plasticizer, 0.2%-1.0% of an antistatic agent, 0.5%-1.0% of a coupling agent and the balance of soft water. The reinforced textile type impregnating compound is suitable for a basalt-reinforced thermosetting phenolic epoxy resin composite material, is good in textile property, and is capable of promoting the binding force of the basalt fiber and the reinforced thermosetting high-molecular polymer.

Description

technical field [0001] The invention relates to a fiber sizing agent and a preparation method thereof, in particular to an epoxy-type sizing agent special for basalt fibers and a preparation method thereof, belonging to the field of fiber sizing agents. Background technique [0002] Basalt is a hard and dense volcanic rock widely found in the crust of most countries in the world. Basalt fibers are manufactured using a continuous process that is in many ways similar to glass fiber drawing. Like E-glass fiber, basalt fiber is also drawn from a platinum-rhodium alloy bushing. The sizing is applied while the fiber is cooling, and the fiber is fed into drawing and winding equipment, where it is wound onto bobbins. It is obviously better than E glass fiber in composite material application, has higher breaking load and higher Young's modulus, someone has done a comparative test, under the same conditions, the strength of basalt epoxy composite material sample is higher than that...
