摘要:
Un sirop acrylique riche en monomère est coulé; il contient entre environ 10 % et environ 20 % des particules acryliques broyées. Durant la solidification, les particules absorbent plus de la moitié de leurs poids en monomère, et une feuille solidifiée est formée; dans ladite feuille, le monomère matriciel et le polymère non réticulé forment une phase qui s'étend à travers les particules, tandis que les particules semblent se fondre ensemble. L'adjonction d'un réticulant dans le sirop assure encore mieux l'interpénétration de la phase matricielle dans les particules gonflées. Une surface texturée est formée. Après thermoformage, elle est utile comme surface antidérapante dans les baignoires et dans les cabines de douches.
摘要:
A monomer-rich acrylic syrup is cast including about 10 % to about 20 % ground acrylic particles. During curing, the particles absorb over half their weight in monomer, and a cured sheet is formed in which the matrix monomer and uncrosslinked polymer form a phase which extends through the particles, while the particles appear to be fused together. Including a crosslinker in the syrup further insures the interpenetration of the matrix phase into the swollen particles. A textured surface is formed, which is useful as an anti-slip surface in bathtubs and shower stalls, after thermoforming.
