Definitions
- Phenol-formaldehyde resins process for their preparation and their use as binders
- the present invention relates to phenol-formaldehyde resins, their preparation and their use particularly as binders for mineral fiber based insulation products, as well as mineral fiber based insulation products containing these phenol-formaldehyde resins as binders.
- Phenol-formaldehyde resins and compositions containing these resins are used in the art, if necessary with the addition of additives, inter alia as binders for insulating products based on mineral fibers.
- Such insulation products are used, for example, in public and non-profit housing, as wall and roof insulation, as well as in industry, for example in the form of technical insulation, use.
- the phenol-formaldehyde resins In order to be usable as such binders, the phenol-formaldehyde resins must have sufficient stability, so that after their preparation and before further processing, especially on mineral fiber based insulation products, essentially no further condensation takes place, which the phenol-formaldehyde resins for make a use as a binder unusable. Namely, an important criterion for the requirement of resins for such applications is the ability to flow on the surface of the mineral fibers to the points of intersection with other mineral fibers, in order to achieve a mechanical fixation there after curing. By an uncontrolled further condensation of the phenol-formaldehyde resins increasingly higher molecular weight oligomers arise that do not have the necessary flow behavior.
- Water-soluble and mono-, di- and trisubstituted phenol derivatives are therefore the preferred substance elements, as they migrate to the crossing points mineral fibers are capable of forming a stable network during curing.
- the binders must retain the ability of infinite water dilutability over an extended period of time.
- infinite water dilutability is meant herein that according to the standard DIN 16916 a predetermined amount of resin with any amounts of softened 20 0 C warm water is miscible without causing precipitation.
- urea as a formaldehyde scavenger in phenol-formaldehyde-based binders for insulating products based on mineral fibers also entails a significant disadvantage if thermal reactions convert portions of the urea into organic amines and into ammonia and these substances during the production process or be dispensed from the finished product.
- thermal reactions convert portions of the urea into organic amines and into ammonia and these substances during the production process or be dispensed from the finished product.
- the nitrogen content of urea has a favorable effect on the reaction to fire, the release of such potential hazardous substances must be taken into account, especially when temperatures above 35O 0 C occur.
- urea as a formaldehyde scavenger is the lower hydrolytic stability of its reaction products with formaldehyde. This means that despite the formation of oligomeric and polymeric structures in the precursors of the
- Urea-formaldehyde resin or in the condensed resins by the action of moisture may lead to a cleavage of these bonds and so formed during the use of the insulating again small but detectable amounts of formaldehyde and released.
- the objectives of the invention are to minimize cleavable and volatile substances and to maximize the efficiency of the binder system while retaining the properties relevant to the manufacture of mineral fiber-based insulating products, such as those mentioned above, of the phenol-formaldehyde resins.
- the objects of the invention are to provide phenol-formaldehyde resins having the properties required for use as binders for mineral fiber-based insulating products, such as sufficient Stability and sufficient water solubility of the resins, and provide resins or binders, which show substantially no or only a very small formaldehyde, a low amine and ammonia emission and thus an increased efficiency, the use of urea as a formaldehyde scavenger and thus the Formation of volatile and potentially toxic materials by reaction of urea contained in the resin or binder is avoided.
- a phenol-formaldehyde resin which comprises alkali-catalyzed condensation of phenol and formaldehyde in the presence of at least one salt of inorganic acids and neutralization by means of an inorganic or organic acid following condensation.
- the preparation is carried out with the addition of at least one compound of the formula R 3 - (CH 2 ) Ii-R 2 (1) in which R 1 , R 2 independently of one another are -C (O) R, -COOR, - CN or NO 2 , where R is H or CH 3 and n is 1 or 2.
- the resins of the invention may have a molar ratio of phenol to formaldehyde of from 1.5 to 3.5, with molar ratios of from 2.0 to 3.0 being preferred.
- the inorganic and organic catalysts known in the art can be used, such as the inorganic hydroxides NaOH, KOH, LiOH, Mg (OH) 2 , Ca (OH) 2 , Ba (OH) 2 and the organic Amines dimethylethanolamine and triethylamine. It is also possible to use mixtures of the catalysts, such as mixtures of organic and inorganic catalysts, mixtures of different organic catalysts and mixtures of different inorganic catalysts.
- the salts of inorganic acids which can be used are the salts described in US Pat. No.
- borax the salt advantageously being used in an amount of from 0.5 to 6.0% by weight, based on the water Total weight of the reaction mixture, is present.
- the borax used according to the invention may be both borax with water of crystallization, for example the decahydrate, and also anhydrous borax.
- the acids used for neutralization are inorganic or organic acids which are known in the art for this purpose, and these can be classified into two categories for the present invention:
- acids such as boric acid, sulfuric acid, phosphoric acid, hydrochloric acid, citric acid and p-toluenesulfonic acid are preferred, which in turn also contain no nitrogen atoms.
- nitrogen-containing compounds are allowed in the binder according to the invention, which is substantially urea-free, then acids such as nitric acid, ammonium sulfate, ammonium nitrate and amidosulfuric acid can be advantageously used, which in turn contain nitrogen atoms.
- the prerequisite for the use of nitrogen-containing compounds is that these compounds fertilize under pyrolysis conditions do not significantly lead to the formation of toxic compounds such as methyl isocyanate.
- Essential for the phenol-formaldehyde resins according to the invention is the combination used in the condensation of salt of an inorganic acid and at least one compound of the formula R 3- - (CH 2 ) HR 2 (I) / wherein R 1 , R 2 are independently -C (O) R, -COOR, -CN or -NO 2 , where R is H or CH 3 and n is 1 or 2. It is preferably a compound of the above formula (1) wherein R 1 , R 2 are independently -C (O) R or -COOR, for example, dicarbonyl compounds such as acetylacetone, methyl acetoacetate and 4-oxopentanal are particularly preferred.
- Polyketones are already used in molding and molding resins (e.g., JP63270720, JP63289055, JP2124917). These are systems wherein the ketones react with aromatic aldehydes. These resins do not have the desired water dilutability, but must be dissolved in organic solvents.

- reaction mixture in an amount of 0.5 to 15 wt .-%, based on the total weight of the reaction mixture, before.
- reaction mixture encompasses phenol, formaldehyde, inorganic salt, the compound of the formula (1) and neutralization acid.
