Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the specific embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them.

[0023] The invention provides a technical solution: a high-durability rock wool formula. The raw materials of rock wool include: 35-50 parts of basalt, 25-30 parts of quartz sand, 20-25 parts of slag, 15-20 parts of perlite, and 12 parts of limestone. -15 parts, 8-10 parts of phenolic resin, 6-8 parts of water-repellent agent, 2-3 parts of adhesive.

[0024] A formulation processing of high durability rock wool includes the following specific steps:

[0025] (1), raw material processing:

[0026] Weigh basalt, slag, perlite and limestone in the above-listed raw materials by weight, then pulverize them, and then fully mix them with a mixer after pulverization;

Abstract

The invention discloses a formula of high-durability rock wool, and relates to the technical field of rock wool. The rock wool comprises the following raw materials: 35-50 parts of basalt, 25-30 partsof quartz sand, 20-25 parts of slag, 15-20 parts of perlite, 12-15 parts of limestone, 8-10 parts of phenolic resin, 6-8 parts of a water repellent, and 2-3 parts of an adhesive. The formula processing of the high-durability rock wool comprises the following specific steps of (1) raw material processing, (2) raw material melting reaction, (3) rock wool fiber forming, (4) wool collecting and pressing and (5) curing finishing. According to the formula of rock wool, the slag is used as the raw material, waste can be recycled, environmental pollution can be reduced, and environmental benefits canbe improved; the basalt can improve the performance of the rock wool, the quartz sand is a nonmetal mineral substance and is a silicate mineral substance which is hard, wear-resistant and stable in chemical performance, and the quartz sand is added so that the strength of the rock wool is improved, the service life of the rock wool is prolonged, and the durability of the rock wool is better.

Description

technical field [0001] The invention relates to the technical field of rock wool, in particular to a high-durability rock wool formula. Background technique [0002] Rock wool products are made of high-quality basalt and dolomite as the main raw materials. After being melted at a high temperature above 1450°C, they are centrifuged into fibers at high speed by an internationally advanced four-axis centrifuge. At the same time, a certain amount of binder, dust-proof oil, and hydrophobic After the agent is collected by the cotton collector, the pendulum method is used, and the cotton is laid by the three-dimensional method to be solidified and cut to form rock wool products of different specifications and uses. [0003] The quality of the rock wool fiber made by the existing rock wool formula is not good, which leads to insufficient durability of the finished rock wool product, which easily affects the quality of use and service life, and the bonding performance of the rock woo...
