preparation example Construction

[0070] The preparation method of this sizing agent comprises the following steps:

[0071] Dilution of 1S film former, surfactant A and surfactant B:

[0072] Dilute the film-forming agent with 1 to 3 times its mass of water; dilute surfactant A with 4 to 6 times its mass of water, and the water temperature is 80 to 95°C; dilute surfactant B with 4 to 6 times its mass diluted with water, the water temperature is 80-95°C;

[0073] Preparation of 2S coupling agent:

[0074] Add water with a total water content of 30% of the wetting agent into the container, sequentially add a pH regulator and a coupling agent, and stir to obtain a dispersion solution of the coupling agent;

[0075] Preparation of 3S sizing agent:

[0076] Add the diluted film-forming agent, surfactant A, and surfactant B obtained in step 1S to the coupling agent dispersion solution obtained in step 2S, supplement the water in the wetting agent formula, and stir evenly to obtain the product.

Embodiment 1

[0080] Weigh each component by mass percentage, and prepare the sizing agent according to the following steps:

[0081] 1S Dilution of film-forming agent, surfactant A and surfactant B: dilute the dimer acid modified epoxy resin emulsion with water 1 to 3 times its mass; dilute the acetylenic diol Germini nonionic surfactant with its Dilute with 4-6 times the mass of water, and the water temperature is 80-95°C; dilute the disemicarbazide polymer cationic surfactant with 4-6 times the mass of water, and the water temperature is 80-95°C;

[0082] Preparation of 2S coupling agent: add water with a total water content of 30% of the wetting agent into the container, add glacial acetic acid and A-151 in sequence, and stir to obtain a coupling agent dispersion solution;

[0083] Preparation of 3S sizing agent: add the diluted dimer acid-modified epoxy resin emulsion, acetylene glycol Germini nonionic surfactant, and diaminocarbamide polymer cationic surfactant prepared in step 1S to ...

Abstract

The invention provides an impregnating agent. The impregnating agent comprises, by mass, 5-7% of a non-aqueous part and the balance water. The non-aqueous part of components in the impregnating agentincludes, by mass, 5-17% of a coupling agent, 45-65% of a film-forming agent, 8-22% of a surfactant A, 8-22% of a surfactant B and 1-7% of a pH value regulator. Direct yarn prepared by adopting the impregnating agent has excellent raw yarn bundling property, is free of splitting and has few wool yarn balls. Pultruded section bars of a prepared alkali-free glass fiber direct yarn reinforced composite material are better in bending strength and surface quality.

Description

technical field [0001] The invention relates to the field of glass fiber sizing agents, in particular to a sizing agent for direct yarns for high-quality surface pultrusion profiles. Background technique [0002] Pultrusion molding technology is a continuous automatic production process for manufacturing composite materials with high glass fiber content, high performance and low cost. , After continuous mold release, the profile products are obtained by cutting to length or certain post-processing. In addition to the corrosion resistance, aging resistance, and insulation properties of traditional FRP materials, materials manufactured by pultrusion technology also have the characteristics of stable product size, good appearance quality, and high production efficiency. Based on the unique properties of the materials manufactured by the pultrusion process, its products can replace traditional materials such as metal, plastic, wood, ceramics, etc., and are widely used in chemic...
