Embodiment 1

[0045] Weigh each component by mass percentage, use the epoxy silane coupling agent with the brand A-187, use the vinyl silane coupling agent with the brand A-174, A-172, use the amino acid with the brand A-1100 Silane coupling agent; use grades of PEG lubricants of PEG400, PEG600, PEG800, and PEG1000; use grades of acrylic modified epoxy resin emulsions of QX-004; use grades of water-based epoxy resin emulsions of MU-609; use The brand name is AMQB-1827 cationic surfactant. Each component is carried out the preparation of non-alkali glass fiber direct yarn sizing agent for pressure vessels according to the following steps:

[0046] 1S Dilution of film-forming agent, surface active agent and lubricant: take the solid content part after the theoretical water removal of the acrylic modified epoxy resin emulsion based on the total amount of non-water component sizing agent of 33%, add the mass of Acrylic modified epoxy resin emulsion quality 1 ~ 3 times the water stirring diluti...

Abstract

The invention provides an impregnating compound. The impregnating compound is used for alkali-free glass fiber direct yarn for a pressure container, and contains a coupling agent A, a coupling agent B, a film forming agent A, a film forming agent B, a surfactant, a lubricant, a pH regulator and water; the mass of non-water components accounts for 4-10% of the total mass of the impregnating compound; based on the total mass of the non-water components, the content and mass percentage of the components are represented as: 4-18% of a coupling agent A, 4-18% of a coupling agent B, 30-60% of theoretical dehydrated solid-containing part of the film forming agent A, 8-40% of theoretical dehydrated solid-containing part of the film forming agent B, 1-13% of surfactant, 1-10% of lubricating agent,and 1-6% of the pH regulator. Direct yarns produced by adopting the impregnating compound is soft, and is good in compatibility with matrix resin, and a pressure container prepared from the direct yarn produced by using the impregnating compound is high in bursting strength and excellent in fatigue resistance.

Description

technical field [0001] The invention relates to the field of glass fiber sizing agents, in particular to a sizing agent for non-alkali glass fiber direct yarns for pressure vessels. Background technique [0002] Pressure vessels are widely used in chemical, petrochemical, pharmaceutical, metallurgy, machinery, mining, electric power, aerospace, transportation, agriculture, civil and military industries, and most pressure vessels need to operate under certain pressure and temperature And the operating conditions are complex. Because the pressure vessel is subjected to various static, dynamic or alternating loads, as well as additional mechanical or temperature loads and most of the containers contain compressed gas or saturated liquid, if the container ruptures, the medium will suddenly depressurize and expand, and the medium will be released instantly. It has the characteristics of extremely large destructive energy and has become a special type of equipment. With the deve...
