Many of these characteristic properties that influence the surface are very closely linked to the local distribution of moisture and bulk density.
- thermal-mechanical surface forming of flat material webs are based on the principle of action of the simultaneous or immediately successive action of heat and pressure on the flat material to be deformed when the web passes between two or more whales ⁇ zen different surface properties, hardness and elasticity.

- smoothing units, calendering calenders, hot gloss presses, smoothing cylinders, soft calenders and similar devices are used for this.
- thermal-mechanical surface treatment have significant disadvantages which arise from the fact that when the materials are heated to higher temperatures, the melting or softening temperatures of components of the material to be treated are reached. This results in partial or complete adhesion of the material webs to the surfaces of the aggregates mentioned, for example by adhesion.
- B. rollers so that it is not possible to exploit the aggregate conditions that can be achieved, for example with regard to the supply of heat and production speeds, for an efficient production flow.

In addition to these substances, film-forming tetrafluoroethylene polymers are used as antiblocking agents in the processing of thermoplastics. In the food industry, the use of separating emulsions based on oil-in-water emulsions from self-emulsifying fatty acid mono- and triglycerides is known. According to this status, anionic co-emulsions of carnauba wax and paraffin wax are used as antiblocking agents for cardboard manufacture according to EP 0 478 177 AI.

- compositions according to the invention in the production of surface-pigmented silicone base papers.
- the invention is illustrated by the following examples; Here, the substance-related percentages relate to the weight of the components.
- Strips of approx. 20 cm wide and approx. 80 cm length of an abrasive base paper impregnated with latex on both sides and subsequently coated with latex on one side of 120 g / m 2 and a total latex content of approx. 25% were at an equilibrium moisture content of approx. 6% in a two-roll laboratory calender from the company Kleinewefers AG, D-47803 Krefeld, smoothed with the highest possible line pressure and increasing temperature of the heated steel roller.
- the counter roll was a cotton hard paper roll analogous to a conventional hard nip calender construction. Even at a surface temperature of the steel roller of approximately 60 ° C., the paper web adhered slightly to the roller, which was increasingly observed at approximately 70 ° C.
- the thermally stable abhesive agent according to the invention consisting of 1.85 parts by weight of a nonionic vegetable oil ethoxylate, 17.1 parts by weight of water and 3.1 parts by weight of di-n-butyl adipate, was applied to the heating roller (steel) and the heating roller was further heated strong adherence of the paper web to the steel roller only at a surface temperature of 150 ° C.
- the effect of sticking when using the abhesive agent therefore only occurred after a temperature increase of over 70 ° C.
- the method of operation possible in this way with greater heating of the material web caused an increase in smoothness from approx. 755 Bekk-s to approx.

While the paper web again began to stick strongly at a surface temperature of the untreated steel roller above 60 ° C., the paper web did not stick to the steel roller treated with the thermally stable abhesive agent according to Example 1 until the surface temperature was approximately 140 ° C.
- the improvements in the surface properties of the processed abrasive base paper were even more pronounced than the improvements described in example 1 due to the higher moisture content of the paper webs before the satin finish (13% instead of 6% in example 1).
- the counter roll had a fiber / plastic cover of 91 ° Sh D hardness analogous to a soft calender construction.
- the calendering was carried out with a moisture content of the paper samples of 7.7 and 9.7%. If the heating roller surface was not treated in accordance with the invention, slight sticking occurred at a surface temperature of 70 ° C. or strong sticking occurred in the paper sample with a higher moisture content. Surface temperatures of over 80 ° C. could not be set for either of the two pre-moistened papers, since the sticking effect led to wrinkling in the paper web. After a surface treatment of the heating roller with the thermally stable abhesive according to Example 1, no sticking of the paper webs at the maximum possible surface temperature could be determined visually.
- Strips approx. 20 cm wide and approx. 80 cm long of a furniture film of 70 g / m 2 pre-impregnated with a mixture of latex and urea-formaldehyde resin and a latex / resin content of approx. 30% were used in a two-roll calender according to Example 1 after heating the steel roller to the maximum possible surface temperature of 150 ° C smoothed.

- Example 4 The tests were repeated analogously to Example 4 with a pre-impregnated furniture film of 80 g / m 2 , but with a very high filler content, the individual samples being which is why the moisture levels of 2.5%, 5.8%, 6.4% and 8.5% were set differently.
- Example 4 The tests were repeated analogously to the conditions of Example 4 with samples of a silicone base paper of 62 g / m 2 pigmented on one side of the surface.
- the coating was 5 g / m 2 with a very high latex content of over 40%.
- the samples were pre-moistened to 4.5%, 8.1%, 9.2% and 12.0% respectively and again stored separately. After the steel roller had been heated to the maximum possible surface temperature of 150 ° C., a slight sticking occurred at 12% on the untreated side of the roller.
- sanding paper with a finish application was satinized at a line pressure of 400 bar, the surface of the steel cylinder being set to temperatures of 70 ° C. or 130 ° C.
- Various abhesive agents in the form of an oil-in-water emulsion were tested, the abhesive agent being applied to the surface by rubbing in the heated steel cylinder.
- the emulsions were formed from 2.0 parts by weight of a fatty alcohol oxyethylate, 11.6 parts by weight of water and 1.3 parts by weight of the abhesive component.
- the abhesive was diluted with water in a ratio of 1: 1 or 1:10 to a furniture pre-impregnate according to Example 4 using a laboratory doctor applicator and then in a two-roll laboratory calender, according to Example 1, at the highest possible line pressure and a surface temperature of the heated steel roll of 150 ° C satined.
- the smoothing level of the paper samples thus satin was 300 ⁇ 30 Bekk-s smoothness.
- a likewise laboratory-satinized paper sample with approx. 300 Bekk-s was used, but without this surface application.
- the data in Table 2 show that the The wetting agent does not significantly change the contact angle to the water in the satin-finished sample, while a significant improvement is achieved in the gloss after painting by using the abhesive in a mixing ratio of 1: 1 with water.
- the gravure printability is changed insignificantly compared to the comparison sample.
- a paper coated with pigment on one side of 50 g / m 2 was smoothed in a technical smoothing machine (soft calender: steel / plastic roller) under the following practical conditions:
- the completely vapor-volatile abhesive consisting of a 10% solution of di-butyl adipate in isopropanol was dosed at 1 l / h. continuously introduced into the heating steam line for the lower steam humidifier.
- experiment 201 2 x 58 kg steam / hour at 120 ° C. be applied before the heating roller was occupied.
- the addition of the fiction abhesive according to example 1 a maximum possible amount of steam of about 1 10 kg steam / hour. be applied without Aass it came to the roller.
- the final moisture content of the paper increased by approximately 0.5% (absolute), so that there was a slight decrease in the values of the surface properties.
- experiment 204 using the abhesive at an elevated roller temperature of 160 ° C, the paper web with a maximum possible amount of steam of 170 kg steam / hour. (total) are applied without any deposits on the smoothing roller being found.
- test data and paper properties after soft calendering with and without the use of the abhesive agent are listed in Table 3 for comparison.
