Cold bonding agent based on bitumen.

COLD CONNECTING AGENT WITH A BITUMEN BASE

The invention relates to a cold-binding agent used in the construction industry, which consists of two components.

5 In numerous areas of the civil engineering and building construction industry there are such adhesive and joint sealing tasks that cannot be carried out either with hot bitumen sealing compounds, but often even with solvent-based or emulsion products. For stain-like repair of roof insulation or for sealing dilatation joints in high-quality buildings (bridges, tunnels, segments) and for filling the joints, various products based on two-component epoxy resin or polyurethane are available, the stone-15 coal tar and / or Bitumen, as well as solvents. The disadvantage of these is that they can generally only be used for specific, specific bonding purposes, or they contain 40-60% solvents and are therefore polluting and flammable.

The bituminous compositions containing solvents or aqueous emulsions, which can also be processed cold, cannot be used, for example, for purposes where drying of the adhesive film is not ensured or the volume decrease (shrinkage) taking place during drying is impossible, e.g. in the case of gluing waterproofing sheets to each other, 5 or when filling dilatation joints. For the repair of concrete roads and railways, tar epoxy or bitumen epoxy materials with a high filler content are generally known, since they adhere well to concrete and have the desired elasticity. Because of the 10 high costs, these are only for special ones

Building objects, e.g. used in the repair of the runways of airfields. Epoxy resin-based adhesives or rubber and synthetic rubber adhesives are known. For joint sealing 15, putties and fillers based on plastic are used, such as products based on polysulfide, butyl rubber, poly-isobutylene, polyurethane or silicone rubber. Their disadvantage is the high cost, which means that they are only used to a limited extent.

20th

The disadvantage of the known products is on the one hand their costlyness, on the other hand the fact that they cannot be used for various purposes. It is, for example, an unsolved problem that the fabric spreads itself in the required layer thickness and thus corrects the unevenness of the surface, or that the position of the material to be bonded also after - 3- the laying, that is Pot life, can be corrected or regulated as desired. The permanently plastic properties can only be achieved with the addition of expensive plastics, and the use of solvents cannot usually be eliminated.

The aim of the invention is the elaboration of a cold applicable, permanently plastic agent of adjustable binding time, which is suitable for several uses 10, is free of water and solvents and is easy to be traded; its use does not cause health and environmental damage.

The agent according to the invention consisting of two components - which is water and solvent free and cold

dend - can be characterized by the fact that component A

40-60% by weight bitumen or with 2-6% by weight

Polybutadiene polystyrene mo- 20 differentiated bitumen 20-40 wt.% Liquid fatty acid 20-40 wt.% Filler 25 and the

Component B

10-20% by weight of 5-10% by weight made from drying or semi-drying vegetable oil and sulfur. % Factual liquid containing sulfur - 4 - 10-20% by weight of zinc oxide, magnesium oxide, alkaline earth metal oxide or hydroxide, or a mixture thereof containing 60-80% by weight of filler, preferably quartz powder or sand of 0-3itm grain size 5 and the mixing ratio of Components A and B 1-3: 3-1 is

The other 'embodiment of the inventive, water- and solvent-free} cold-binding agent consisting of two components can be characterized in that the

Component A

40-60% by weight of bitumen 20-40% by weight of liquid fatty acid with an average number of 15 carbon atoms or naphthenic acid 5-10% by weight of sulfur factories made from pretreated rapeseed oil and sulfur of 17-19 20% by weight of total sulfur content, the

Component B

10-20% by weight of zinc oxide, magnesium oxide, calcium oxide (; quick lime or hydroxide, or chlorine lime or a mixture thereof 25 10-90% by weight of filler contains 1-20% by weight of rubber powder and the mixing ratio of components A and B 1-3 : 3-1 is.

.-5-

The bitumen is modified with 2-8% by weight or 2-6% by weight of thermoplastic mixed polymer of the type SBR or SBS. Such products are Euro-pren 161A and 161B (Enichem, Italy), Catiflex 1101, 1184, 5 1186 (Shell Co.), Finapren 411, Claprene (Shell). The mol weight of these products (synthetic rubber) is 120-280,000. The liquid fatty acid can be talc oil fatty acid, the C iodine number of which is 84-92. Tallow fatty acid, technical fatty acid with oodine number 20, saponification number 10 185-210, sunflower oil fatty acid, rapeseed oil fatty acid, palm kernel oil fatty acid, coconut oil fatty acid or linseed oil fatty acid can be used as the fatty acid. The inert filler with 0-1 mm grain size is sand or quartz powder, andesite, basalt, rock powder, talc, kaolin, bentonite or clay, microsilica-15 powder, alumina hydrate, corundum powder, asbestos drum, mineral wool, plastic fiber, viscose fiber, etc. or their mixture. The drying or semi-drying oil - suitable for factoring - is sunflower, rapeseed, cottonseed, pumpkin seed, sesame, hempseed, olive, soybean, 20 fish, corn, linseed or castor oil ood number is 80-200, but a dry vegetable oil varnish can also be used. The quality and composition of the inert filler can be the previous one, but the use of sand with 0-1 mm grain size is advantageous. The ratio of components A and B can be varied within the specified limits, but it should be noted that a 2: 1 mixture is used for bonding purposes, while a 1: 1 mixture is advisable for joint sealing - 6.

The agent according to the invention is produced in such a way that bitumen below its softening point - expediently between 160-180 ° C. - below

Stirring with the thermoplastic SBS mixed polymer was added gradually, the liquid oleic acid was added to the homogenized mixture with vigorous stirring and the filler was still warm, the mixture was allowed to cool to 10 30-40 ° C., and the component A obtained

stored separately.

In a separate step, a factice with 8-10% by weight 15 total sulfur content is cooked from dry vegetable oil and sulfur. After cooling, the zinc or magnesium oxide or the alkaline earth metal oxides are mixed with the mixture until homogenization, then the components B obtained in this way are homogenized after the addition of the fillers. Adherence to the mixing sequence of the components is expedient; the stability of the product will be better if the specified mix order is used.

Alternatively, when producing component A, the bitumen is mixed with the hard or semi-hard factice at 160-170 ° C, then with oleic acid, in a separate step the zinc or magnesium oxide or the alkali earth metal oxides or the chlorine lime, the fillers and added the gum and homogenized.

- 7 -

The essential prerequisite for the use of the agent is the complete and complete mixing of components A and B, in general mixing times of 5-10 minutes are sufficient. The pot life of the liquid, 5 mortar-like mass is 2-2.5 depending on the temperature

Hours, but the pot life can be extended or significantly reduced by adding an aliphatic carboxylic acid to component A - at most 5% based on the mass of the same - essentially regulating between 10 minutes and 24 hours * During the pot life, the mortar-like mass thickens not, spreads well by itself, after a certain time the setting starts suddenly, the mass hardens in 10-15 minutes, but the permanent plastic state remains * 15

The composition of the agent according to the invention is new, similar bituminous adhesive or similar agent for joint sealing is not commercially available and has not become known. The setting of the agent takes place in the cold state at ambient temperature, preferably at temperatures of about 20 ° C and is presumably composed of three sub-processes;

With the saponification between the metal oxide used and the free fatty acid, a bond is formed, the duration of which can be regulated * This time can be shortened by adding an aliphatic carboxylic acid, - 8 - by adding factice, the bond can be inhibited , their duration increases. Simultaneously with this process, partially or completely crosslinked bonds are formed between factice, metal oxide, unsaturated fatty acid and possibly the unsaturated bonds of the synthetic rubber. In the layers of the bound mass that come into contact with air and light, the unsaponified residue of the semi-saturated vegetable oil and the unsaturated fatty acid hardens for a comparatively long time with oxygen absorption, where the mass used "hardens". This can be seen from the cessation of stickiness and slowly increasing the softening point.

15 The agent according to the invention has the advantage that the layer thickness can be varied in use, the rapid start of the setting does not have to be expected, the mass "spreads". As a result of the controllability, the position 20 (position) of the materials to be bonded can also be according to the

Align the installation, the material to be glued is not damaged by heat or chemical influences. After use, the mass remains plastic and takes over the movements without the formation of cracks. The mass adheres well to a dry basis, after which the layer becomes moisture-resistant, does not absorb water and sets even under water. When the agent - 9 - is used in practice, the gluing, joint sealing or other work can be carried out with simple devices without the risk of fire and damage to health, does not require any skilled workers. The agents according to the invention 5 can be used, inter alia, for filling joints in concrete passages, roof insulation elements , for gluing parquet, use roofing membranes. Their use is extremely economical, since the active substance content of the product can be composed of cheaply available components. By changing the ratio of components A and B, the character of the agent can also be varied.

Further details of the invention are shown with 15 exemplary embodiments.

example 1

A mass 20 suitable for joint pouring is produced from the following components:

Component A: 38% by weight situmen B-90 (softening point 46 ° C, penetration 71-100) 2% by weight styrene-butadiene copolymer (Europrene 25 16lA), average molecular weight 280,000 20% by weight oleic acid (oleic) 40% by weight % Sand of 0-1 mm grain size component B: 10% by weight of liquid factice made from sunflower oil and sulfur, 10% by weight sulfur containing liquid 10% by weight zinc oxide (zinc white) 80% by weight sand of 0-1 mm grain size 5 ln Component B can be used instead of vegetable oil, partially or completely liquid coal tar or liquid petrol pyroliseteer.

To produce component A, the 10 bitumen is heated in a heatable device equipped with a stirrer with vigorous stirring to 180 ° C. with the addition of the mixed polymer in 45-60 minutes. Then add the oleic acid to the homogeneous mixture, stir vigorously for a few minutes, then add the fine sand to the still warm mixture 15 with further stirring. The stirring is continued with water cooling until the temperature of the mixture becomes 35-40 ° C. The black, liquid product is then filled into containers. In the production of component B, the fact from dry vegetable oil and sulfur is first prepared by heating the vegetable oil to 130-140 ° C, adding the powdered or lamellar sulfur and at this temperature for 3-4 hours until completely Installation of the sulfur stirs. The resulting vegetable oil extract forms a dark brown liquid that is transparent in 25 strong light and free of deposits and turbidity. The cooled liquid factice is mixed with the zinc oxide (zinc white) in a homogeneous paste. Then - 11 ^ the fine sand is added * You get a so-called earth moist mass whose color and appearance is similar to the wet sand and can be packed in sacks. Components A and B produced in this way are mixed at a ratio of 1: 15 by mass in small quantities by hand, in larger quantities by machine. Complete mixing can be achieved in 5-10 minutes. The pot life of the liquid and self-spreading pouring compound thus produced is 10-2-2.5 hours depending on the temperature, during this period it does not thicken, flows well and spreads. Then the setting suddenly begins, especially at a temperature above 20 ° C, the mass sets in the joint or in the "pot" in 10-15 minutes.
