Because minerals such as ore, pyrrhotite, perlite, slag, glass, limestone and the like are manufactured according to a certain proportion, the proportion of magnesium, calcium and iron elements in the rock wool can reach triangular balance, a certain amount of auxiliary substances such as a water repellent, a bonding agent and the like are added in the manufacturing process, the fiber forming effect is good, the fiber distribution is uniform, and the rock wool board obtained by pressing has reasonable density gradient and has very good sound absorption and sound insulation functions; urea, phenolic resin and 3-aminopropyltriethoxysilane are sprayed simultaneously in the fiberization process, the urea reacts with the phenolic resin by using the temperature of the cellosilk and the alkaline components in the cellosilk, and the 3-aminopropyltriethoxysilane can remarkably promote the bonding effect of the phenolic resin, so that the bonding property of the cellosilk is improved by about 30 percent.
And S102, sending the rock wool obtained through the cotton collecting treatment into a stirrer in a fan blowing mode for stirring and curing treatment.
Collecting fibers which are centrifugally thrown out, superposing the fibers into S-shaped multi-layer loose rock wool boards, meanwhile, putting resin, lime and gypsum which are obtained according to a proportion into a stirrer to be uniformly stirred at a constant speed, after the uniform stirring, sending all the collected rock wool boards into the stirrer in a fan uniform speed blowing mode to be mixed with uniformly mixed curing materials until the materials are uniformly stirred, at least stirring for more than half an hour, then putting the materials into a mould to be naturally foamed, pressing the materials by using a three-dimensional cotton press, pressing the rock wool by using a differential compression mode of a fancy roller, namely a mode of two sets of differential compression and one set of constant speed compression, and then spraying a water repellent; the three-dimensional cotton pressing machine comprises three groups of upper and lower pressing rollers, wherein one group of pressing rollers at the inlet of the cotton pressing machine is called a first group of pressing rollers, the next group of pressing rollers adjacent to the first group of pressing rollers is called a second group of pressing rollers, the last group of pressing rollers is a third group of pressing rollers, and the pressing rollers of the first group of pressing rollers pressThe roller sets are horizontally distributed, the upper compression roller set has an opening angle (the angle is about 35 degrees, the effect is best, the angle is small, the rock wool layer can not smoothly enter the compression rollers, the angle is too large, the rock wool layer is easy to crowd and stack at the entrance), an opening entrance is formed, and a speed difference V is formed between the upper compression roller and the lower compression roller of the first compression roller set1And the upper and lower press rolls of the second group of press rolls have no speed difference, and the upper and lower press rolls of the third group of press rolls have a speed difference V2Convenient for the output of rock wool board, if the speed difference is V1If positive, the speed difference V2Is negative and vice versa, and the speed difference V1Satisfies | V with the speed difference V21|≥|V2In the three groups of press rolls, fancy press rolls are adopted, and each fancy press roll is provided with a protruding press roll sheet and a press roll groove distributed among the press roll sheets; by adopting differential compression of the fancy roller, the rock wool not only forms wrinkles in the thickness direction, but also forms lap joints among different layers of the wrinkles, thereby forming a three-dimensional structure which is staggered in a three-dimensional way, so that the performance of rock wool products in various dimensions is enhanced, and the peel resistance is greatly improved; when the third group of compression rollers outputs the rock wool board, a water repellent is sprayed on the surface of the rock wool board, a plurality of sound absorption holes are drilled in the rock wool board, the sound absorption holes are additionally formed before solidification, drilling of the sound absorption holes is facilitated, evaporation during fixing is facilitated, and when the drilled sound absorption holes are used, a sound insulation effect can be improved; and then, after the rock wool board is dried at 100 ℃ for 10-15h in a heat preservation way, the temperature is increased to 260-300 ℃ for curing for 5-10h, and because the sound absorption holes are drilled, the water in the rock wool board can be evaporated from the sound absorption holes during drying, and the temperature is close to the gasification temperature of water, so that the drying time is properly increased, the complete evaporation of the water in the rock wool board is ensured, the curing time can be properly reduced, and the curing effect of the rock wool board can be ensured. Meanwhile, as the water repellent and the vinyl tert-butyl tri-peroxide silane are sprayed before curing, the vinyl tert-butyl tri-peroxide silane can not only enhance the crosslinking effect among the fiber yarns, but also improve the hydrophobicity of the fiber yarns, and simultaneously ensure that the sound absorption and noise reduction performance of the rock wool board is more stable.
