Sizing composition in the form of a physical gel for glass strands, glass strands obtained and composites comprising the said strands

摘要

The present invention relates to a sizing composition in the form of a physical gel for glass strands which contains 0.1 to 5% by weight of at least one texturing agent chosen from xanthans, guars and succinoglycans, 2 to 8% by weight of at least one film-forming agent, 0.1 to 8% by weight of at least one compound chosen from plasticizing agents, surface-active agents and dispersing agents, 0.1 to 4% by weight of at least one coupling agent, and 0 to 6% by weight of at least one additive. Another subject-matter of the present invention is glass strands coated with the abovementioned sizing composition and the composite materials containing an organic or inorganic material reinforced with the said glass strands.

主权项

1. A glass strand coated with a sizing composition consisting of, by weight percent:
from 0.1 to 5% of at least one succinoglycan as a texturing agent; from 2 to 8% of at least one epoxy compound as a film-forming agent; from 0.1 to 8% of at least one compound selected from the group consisting of a plasticizing agent, a surface-active agent, and a dispersing agent; from 0.1 to 4% of at least one coupling agent; and from 0 to 6% of at least one additive, wherein the amount of size represents from 0.2 to 5% by weight of a final strand.
