Embodiment 1

[0028] A lubricating glass fiber sizing is made of the following components by weight:

[0029] 40 parts of polyvinyl acetate, 20 parts of water-based polyurethane, 5 parts of castor oil, 3 parts of coupling agent, 0.5 parts of nonionic lubricant, 0.5 part of pH regulator, 0.5 part of emulsifier, 0.5 part of cationic lubricant, antistatic agent 0.1 part, 0.5 part of defoamer, appropriate amount of deionized water.

[0030] The nonionic lubricant is a silicone emulsion. The cationic lubricant is a long chain polyalkylimine compound. Lubricants are used to provide additional protection to the fibers during winding and also reduce fuzzing.

[0031] Described coupling agent is selected from the mixture of γ-glycidyl etheroxypropyl trimethoxysilane, γ-aminopropyl triethoxysilane, vinyltrimethoxysilane, and the mass ratio of the three is 1: 1-3: 1-3. The coupling agent is an important part of the sizing agent. The coupling agent is also called a surface treatment agent, which is...

Abstract

The invention discloses a lubrication glass fiber impregnating agent. The lubrication glass fiber impregnating agent is prepared from, by weight, 40-50 parts of polyvinyl acetate, 20-30 parts of waterborne polyurethane, 5-8 parts of castor oil, 3-5 parts of a coupling agent, 0.5-2 parts of nonionic lubricant, 0.5-1 part of a pH conditioning agent, 0.5-1 part of an emulsifier, 0.5-2 parts of a cation lubricant, 0-0.5 part of an antistatic agent, 0.5-1 part of a defoaming agent and a proper amount of deionized water. The better strength is given to yarn, and the impregnating effect in the impregnating process is improved. Various high-performance lubricants are adopted, and the good weaving effect is achieved while the good impregnating effect is ensured. Three coupling agents are adopted in a combination mode, and the combination effect between the glass fiber and resin is well ensured; the components are wide in source, the moisturizing performance and heat stability are good, and the agent is applicable to glass fiber moisturizing under various conditions, environmental pollution will not be caused, and the impregnating agent is simpler in formula component, the compatibility with resin is good, and the better mechanical property is given to composite materials.

Description

technical field [0001] The invention relates to glass fiber production technology, in particular to a lubricating glass fiber sizing agent. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields. [0003] The sizi...
