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 pee

Embodiment 1

[0027] Embodiment 1: 75 parts by weight of basalt, 6 parts of limestone, 10 parts of slag, 25 parts of coke, 3 parts of fluorite, and 1 part of diatomaceous earth are mixed and pulverized and added to the cupola. The furnace temperature is 1470-1570 ° C. Liquid oxygen is injected, melted, and the magma is formed into fibers through a four-roller centrifuge, and a phenolic resin binder is sprayed at the exit. After the cotton is collected and the pendulum machine spreads the cotton, it enters the cotton press machine and is solidified to form a three-dimensional structure rock wool. Rock wool has a tensile strength of 26kPa and a compressive strength of 85kPa.

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...
