Manufacturing method of novel rock wool material

Abstract

The invention discloses a manufacturing method of a novel rock wool material. The manufacturing method comprises the following steps: blending the following materials in parts by weight: 70-80 parts of basalt, 5-8 parts of limestone, 8-10 parts of slag, 20-30 parts of coke and 3-5 parts of auxiliary materials into a mixed raw material, placing into a cupola furnace, and fusing into magma at temperature lower than 900 DEG C; then forming a fiber, collecting wool, and paving the wool; then pressing on a three-dimensional wool presser, and solidifying and modifying to form the novel rock wool material. The rock wool material manufactured through the method disclosed by the invention has the advantages of uniformity in distribution, good hydrophobic effect and good mechanical property.

Description

technical field [0001] The invention relates to the field of new rock wool materials, in particular to a method for manufacturing a new rock wool material. Background technique [0002] Rock wool is an inorganic material, a fiber aggregate made of natural mineral rocks. The existing rock wool manufacturing process involves the fibers formed by blown magma filaments formed by melting the ore feed, and laying out a loose multi-layer rock wool layer through a pendulum. This multi-layer rock wool passes through the upper and lower rollers of the cotton press machine. After compaction, it enters the curing furnace for curing to form rock wool products. Ordinary rock wool produced by this process only has two-dimensional lamination in the thickness direction without cross-linking, so the peel strength is very low. When it is used as a building material, it is necessary to use rivets in the thickness direction, etc. The workpiece is further fixed, which affects the construction p...

Utility model patent CN201220326750 discloses a rock wool setting system with wrinkling function, but it does not disclose details of how to achieve wrinkling

Chinese patent application 201010512495.8 discloses a rock wool pleating machine, which realizes the pleating of rock wool through the speed difference of multiple sets of upper and lower pressure rollers. The products obtained by this pleating method make each rock wool layer wrinkle. Wrinkles produce component force in the thickness direction, which is beneficial to improve the peel strength of rock wool products, but according to the product principle, it can not establish a connection between layers, so the effect on improving the peel strength is limited, and the actual sales in the market The product also confirms this

Another disadvantage is that the undulating folds in the rock wool product actually increase the tensile allowance of the rock wool layer in the longitudinal direction, giving the rock wool product more elasticity in the longitudinal and thickness directions. , this property is often not desirable
