- L ⁇ sung (commercial polyvinyl alcohol having a degree of hydrolysis of 88 mol% and having a viscosity, in 4% strength aqueous solution of 5.5 mPas (Höppler method at 2O 0 C, DIN 53015)), 65.4 g of a 20% aqueous dodecylbenzenesulfonate solution, 934 mg of mercaptopropionic acid, 411 mg of sodium formaldehyde sulfoxylate and 7.2 g of a 25% aqueous sodium vinylsulfonate solution and 372 g of vinyl acetate emulsified. It was heated to 45 0 C and saturated with ethylene to 47 bar, which corresponds to 309 g of ethylene.
- a 3% by weight aqueous potassium persulfate solution and a 10% by weight aqueous sodium formaldehyde sulfoxylate solution were added simultaneously but spatially separated until the polymerization was initiated (indicated by a rise in temperature and pressure). Subsequently, over 270 minutes, a mixture of 1500 g of vinyl acetate and 3.74 g of mercaptopropionic acid and a 3 wt .-% aqueous potassium persulfate ⁇ metering rate: 53 ml / h) and a 10 wt .-% strength sodium formaldehyde sulfoxylate solution (dosing rate: 12 ml / h) were added separately.
- the mineral fiber mat thus obtained had a footprint of 35 cm x 40 cm, a height of 1 to 2 mm, a basis weight of 450 ⁇ 10 g / m 2 , a water content of ⁇ 0.3 wt .-%, based on the total mass of respective mineral fiber mat, as well as a content of the respective vinyl ester-ethylene copolymer as indicated in Table 1 (The values mentioned were determined according to EN29073, Part 2).
- Solubility is characterized by the time required to dissolve the fabric of the mineral fiber mat, i. dissolve the binder of the mineral fiber mat.
- Tensile strength (Tensile strength) of mineral fiber mats (HZK) The tensile strength of the respective mineral fiber mat was determined using a tensile testing machine (Zwick 1445) according to DIN EN ISO 527, Part 1 to 3.
- the clamping length was 150 mm, the sample width 100 mm.
- the pre-load was 0.1 N and it was measured at a test speed of 200 mm / min.
- Block test of the mineral fiber mats Testing of the blocking or bonding of mineral fiber mats during storage: From the respective mineral fiber mat 3 test pieces with a base area of 6 cm x 8 cm were cut out and stacked with the base areas (stack). The stack was placed between two glass plates so that the bases of the stack were completely covered by the two glass plates (compacts). The compact was placed with one of his glass plates on a solid surface, a weight of 3, 8 kg applied centrally, heated to 4O 0 C and stored for 24 h at this temperature. After cooling to room temperature, the weight and the
- the stack is easy to disassemble into the three specimens, with a slight noise.
- the surface of the specimens is not damaged. That There is very little adhesion between the test pieces in the stacks.
- the stack can hardly be dismantled into test pieces. In the separation test, the surface of the specimens is damaged. That the specimens adhere significantly to each other.
- the stack can not be broken down into test pieces without completely damaging the surface of the individual test pieces; i.e. the adhesion between the specimens in the stack is stronger than the adhesion of the mineral fibers within a specimen.
- the Bull's eye test was performed according to ISO TR3717-1975 (Textile glass mat and woven fabrics determination of wet-out time by resin).
- the respective mineral fiber mat was placed on a glass plate under which was a bull's eye (bull's eye), and weighed down with a metal ring.
- the imprint on the target was completely obscured by the mineral fiber mat and was no longer visible.
- the respective curable resin composition was poured onto the respective mineral fiber mat and the time was measured until the imprint on the target disc became clearly visible again, ie until the thus treated mineral fiber mat became transparent.
- Table 1 Results of the performance testing of the mineral fiber mats:
- the mineral fiber mats according to the invention but in contrast to the common mineral fiber mats no plasticizers.
- a curable resin composition was used in the present example, the 16.07 g of a polyester-styrene resin mixture and 0.273 ml of the initiator Butanox M-50 (trade name of the company Akzo-Nobel) and 0.07 ml of the catalyst Ac celerator NL49P (trade name of Akzo-Nobel). From the mineral fiber mat of Example 4 5 pieces of 7 cm x 8 cm base were cut (CSM piece). The 5 CSM pieces total 10.71 g.
- Part of the curable resin composition was applied to this CSM piece with a brush so that the mineral fiber mat was impregnated with the curable resin composition.
- Another CSM piece was placed on the CSM piece treated in this way.
- the other 3 CSM pieces were applied in an analogous manner.
- the last applied fifth CSM-piece was covered with a polyethylene terephthalate-polyester film, which was also treated with the film release agent PVA ⁇ from R & G) and solidified with a teflon roller, whereby no curable resin composition was pressed out of the laminate.
- the resulting laminate was cured for 24 h at room temperature. After detachment of the polyethylene terephthalate polyester films, a homogeneous mineral fiber-reinforced plastic component was obtained, in which no large inclusions such as air bubbles or mineral fiber bundles were seen.
- the proportion of mineral fibers was 40 wt .-%, based on the total mass of the mineral fiber reinforced plastic component.
