Description

Process for the manufacture of floor, table, wall and other Covering materials It is known to floor, table, wall and others. Coverings from cross-linked polyesters and polyvinyl, compounding gels to produce. It is also known that .the plasticization of polyvinylchloride, d; mainly with Using liquid plasticizers at temperatures around 1C5 ° C. Carried out wind. These Plasticizers are mostly high-boiling esters: the phosphorus exterior, such as B. tricresyl phosphate, or esters of dibasic acids, such as. B. Pht! H: al.acid, and long-chain monohydric alcohols, such as. B. B: utylallcdh @ ol, hexyl alcohol, octyl alcohol and others, or else Estler .au; s monobasic! i, higher bed acids and polyvalent ones Alcohols such as glycols, pentaerythritol and; .other. These plasticizers do have have a relatively high boiling point, but are already higher at room temperature or less volatile, so that the desired degree of softness is plastic Masses cannot be preserved in the long run. Furthermore: most of these Plasticizer in gasoline cave: nwa: extremely: freely soluble. This egg, gen @ s @ chaft works are disadvantageous in floor coverings, since the common polishing compounds are petrol hydrocarbons contain. Due to the constant use of this flooring compound, the flooring becomes softener withdrawn, whereby his Gesdhmei.d! ig.1: e also diminishes in the course of time.

Suitable as a plasticizer for petrol-resistant polyvinyl chloride masks cooking mole cular, linear condensation products, their chemical ones Nature, like polyester from dibasic acids and dihydric alcohols, such as z. B. Adipsns: acid and butyl, englylcol. These are liquid up viscous: bodies of very low volatility, which, however; with increased Temperature d * become fluid. The production of binders from Polyv1nylch: l.orid- with such linear polyesters is not possible without the addition of liquid plasticizers expedient, since on the one hand the strength of the plastic and also. , the binding capacity @ The same suffers from it, but on the other hand the additives of liquid plasticizers increase the recovered petrol resistance partially up again.

Plasins.che masses based on polyvinylchloride as a binder, the a) are manufactured exclusively with liquid plasticizers, also have a poor reception, i.e. the ability to fill up. It is therefore practical not succeeded in using these plastic masses to produce high-quality coverings filled with fillers.

It is also known that polyvinyl chloride with and without additives Liquid plasticizer can be combined with linear and crosslinked polyesters or that For example, the use of polyvinyl compounds based on cross-linked Polvestern is an option allow.

: New in-depth investigations and experiments have shown that you coverings with good properties with a binder made of Polyv inylverbindungen and liquid plasticizers that can produce at least 150% of its. Gelvichtes of fillers, which mainly consist of organic fillers, such as cork flour and wood flour, exist, .absorbs, if one is used as a binder, mixture of Polyvin.ylchlorid and polyvinyl acetate or a mixed polymer from the corresponding monomers used with liquid plasticizers and crosslinked polyesters.

Suitable crosslinked polyesters are obtained by condensation of dibasic acids, such as. B. Ad ipic acid, sebacic acid, succinic acid and others with idirei and polyhydric alcohols, e.g. B. hexanetriol, butanetriol, Trimethylolpropane, pentaarythritol and .andiene. The delbei used Mixtures of the polyvinyl vene compounds can (by simply mixing the individual Turn polymers produced, on the other hand also (already: ih a special mixing or Copolymei - izations.

The special characteristic of such bindings is an increased filler absorption capacity, which cannot be achieved with the usual plasticized polyvinyl compounds. In order to achieve an optimal filler absorption, the condensation must. this polyester be interrupted at a certain degree of crosslinking. The networking must, however, have progressed so far. that a material which is tough and elastic at room temperature is obtained, but which is plastic at the processing temperatures of 130 to 160 ° C. without becoming liquid. If the material becomes liquid at the processing temperatures, the degree of crosslinking is not yet sufficient. On the other hand, products that are crosslinked too far are difficult to process because these materials are no longer plastic at the processing temperatures. lukewarm little and too strong networked products! also only cause insufficient filler absorption. The final condensation only takes place in the finished surface by reheating at temperatures of 60 to 100 ° C.

By adding rosin, rosin esters b @ zw. Abietic acid or Abieti.nsäureestern can be. the properties of the coverings. vary widely. These materials can be used in the manufacture of the plastic sill from polyvinylchl, ori, d, and polyvinyl acetate as above in the mixing process with the fillers or else the polyesters are added during the previous condensation.

Furthermore it is. possible, the mixture or the mixed: polymer also made of polyvinylchloride, d- and polyvinyl acetate, other polymers or Mi, sc'h @ add polymerisabe, such as. B. Polyacrylisä@uree.ster, polystyrene, polyvinyl ether. Example i 15 parts of polyvinyl chloride, 5 parts of polyvinyl acetate, 10 parts of phthalic acid: diibutyl ester and io parts condensate product. 50 parts of adipic acid, 30 parts of hexanetriol and 20 parts of rosin are kneaded in a kneading machine at 130 ° to form plastic. 25 parts of corkscrew, 25 parts of wood flour and 10 parts of paint are placed on this. The mixture obtained, a.ss, e can be converted into covering panels by rolling or pressing deform. Example 2 22 parts of a copolymer of 90 parts of vinyl chloride, i.e. and 10 parts of vinyl acetate are, as described under i., at 15o ° with 8 parts Phenol esters made from: sulfochlorinated Fischer-Tropsch hydrocarbons, 3 parts of abietic acid pentetythritol ester and 7 parts of polyester from q: 3 parts of adipic acid, 17.5 parts of succinic acid and ' 39.5 parts of Trsme # ühylolprop: an processed into a plastic, which is also used as Binder for covering materials can be used.
