Definitions
- the present invention relates to copolymers based on unsaturated mono- or dicarboxylic acid derivatives and oxyalkylene glycol alkenyl ethers, processes for their preparation and the use of these copolymers as additives for aqueous suspensions based on mineral or bituminous binders.
- aqueous suspensions of hydraulic binders are used to improve their processability, i. H. Kneadability, spreadability, sprayability, pumpability or flowability, often with additives in the form of dispersants.
- additives which generally contain ionic groups, are able to break up solid agglomerates, to disperse the particles formed and in this way to improve the processability, especially of highly concentrated suspensions.
- This effect is specifically used in the production of building material mixtures, on the basis of cement, lime and calcium sulfate-based hydraulic binders, possibly also in a mixture with organic (e.g. bituminous) components and continues to be used for ceramic materials, refractory materials and oilfield building materials.
- additives are used, which are generally considered Water reduction or eluent can be called.
- Water reduction or eluent can be called.
- additives especially polycondensation products based on naphthalene or alkylnaphthalenesulfonic acids (see EP-A 214412) or melamine-formaldehyde resins containing sulfonic acid groups (see DE-PS 16 71 017) are known.
- a disadvantage of these admixtures is the fact that their excellent liquefying effect, especially in concrete construction, only lasts for a short period of time.
- the drop in the processability of concrete mixes ("slump loss") in a short time can lead to problems in particular where there is a long period of time between the production and installation of the fresh concrete, for example due to long conveying and transport routes.
- the problem of segregation according to DE 195 13 126 AI can be solved by fully or at least partially incorporating a defoaming or anti-air-introducing structural unit into the copolymer.
- copolymers of this type do not have the optimum properties, in particular, where a particularly tightly bonded and therefore high-strength and highly resistant concrete is to be produced with the lowest possible water content and steam hardening (precast industry) to accelerate the hardening process should be avoided.
- copolymers of unsaturated mono- or dicarboxylic acid derivatives and oxyalkylene glycol alkenyl ethers have been proposed according to DE 199 26 611 A1, which can maintain the processability of highly concentrated building material mixtures for a long time in practice with a low dosage, with an extreme lowering of the water / binder - Ratio at the same time increased strength in the hardened state of the building material.
- a disadvantage of these copolymers with relatively short side chains was that the early strength development of the corresponding building material mixtures was not optimal.
