Abstract
The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials of the invention are suitable for the manufacture of lining materials which can be used in the manufacture of sarking membranes, roofing sheets and water-proof sheetings, in particular of coated sarking membranes, roofing sheets and water-proof sheetings, or in the manufacture of carpets and PVC floorings as a textile backing or as a textile reinforcement.
Claims35
A binder system, comprising:
- a) 10 to 90% by weight, preferably 30 to 70% by weight of at least one polyvinyl acetate and
- b) 90 to 10% by weight, preferably 70 to 30% by weight of one or more starches and
- c) 0 to 60% by weight of at least one additive selected from the group of amphoteric hydroxides, salts of the first and second main groups of the periodic table, mineral additives which are of synthetic or natural origin, kaolin, carbon blacks or mixtures thereof and
- d) 0 to 10% by weight of additives,
- the information on the proportions by weight referring to the dry mass of the binder system, i.e. without water and the sum of the constituents a) to d) giving 100% by weight.

A binder system, comprising:
- a) 10 to 90% by weight, preferably 30 to 70% by weight of polymerizates based on carboxylic acid derivatives and
- b) 90 to 10% by weight, preferably 70 to 30% by weight of one or more starches and
- c) 0 to 60% by weight of at least one additive selected from the group of amphoteric hydroxides, salts of the first and second main groups of the periodic table, mineral additives which are of synthetic or natural origin, kaolin, carbon blacks or mixtures thereof and
- d) 0 to 10% by weight of additives,
- the information on the proportions by weight referring to the dry mass of the binder system, i.e. without water and the sum of the constituents a) to d) giving 100% by weight, and the polymerizates based on carboxylic acid derivatives having been obtained by means of polymerization of monomeric carboxylic acid derivatives which have at least one terminal double bond.
