Abstract
The invention relates to a new adhesive composition and to sheets produced from it, for producing laminates, more particularly for bonding plastic with glass components, to a method for producing such laminates, and to the laminates produced accordingly.
Claims18
An adhesive composition for producing a laminate, comprising
- a) from 10 to 60 wt. % of polyisobutyl methacrylate, isobutyl methacrylate or a mixture thereof,
- b) from 0 to 80 wt. % of butyl acrylate,
- c) from 0 to 50 wt. % of polybutyl acrylate,
- d) from 0 to 5 wt. % of at least one (meth)acrylate of the formula (I)
- where X=O or N, R3 is a hydrogen atom or a methyl group, and R4 denotes an aliphatic or cycloaliphatic radical having from 1 to 20 carbon atoms that has at least one hydroxyl group, thiol group, primary amino group, secondary amino group, and/or an epoxy group, and
- e) from 0 to 5 wt. % of at least one silicon compound obtained by reacting 0 to 5 parts by weight of at least one silicon compound of the formula (II):
- SimR1nR2oOrXs (II)
- where R1 independently at each occurrence denotes an alkenyl or cycloalkenyl radical having from 2 to 12 carbon atoms that may have one or more ester groups,
- R2 independently at each occurrence denotes an alkyl or cycloalkyl radical having from 1 to 12 carbon atoms,
- X independently at each occurrence represents a halogen atom or an alkoxy group having from 1 to 6 carbon atoms,
- m is an integer greater than or equal to 1,
- n is an integer between 1 and 2*m+1,
- o is an integer between 0 and 2*m,
- r is an integer between 0 and m−1,
- s is an integer between 1 and 2*m+1, and
- where m, n, o and s satisfy the relation (1):
- n+o+s=2*m+2 (1)
- with from 0.01 to 2 parts by weight of water and from 0 to 4.0 parts by weight of at least one acid,
- where components a) to e) total 100 wt. % and b) and c) comprise from 30 to 90 wt. %, based on the sum total of components a) to e),
- and where the adhesive composition may optionally further comprise from 0.1 to 6 wt. %, based on the total weight of the adhesive composition, of further additives different from components a) to e).
