Abstract

The invention discloses a lignin rock wool phenolic resin binder and its preparation method and use method. The lignin rock wool phenolic resin binder comprises components A, B and C. The component A comprises, by weight, 100 parts of lignin rock wool phenolic resin, 40-60 parts of ammonia water, 180-220 parts of fine-filtered water and 0.4-0.8 parts of a coupling agent. The component B comprises, by weight, 100 parts of anti-dust oil and 180-220 parts of fine-filtered water. The component C comprises, by weight, 100 parts of a water repellent and 180-220 parts of fine-filtered water. The lignin rock wool phenolic resin binder has long-term storage stability, excellent waterproof performances and bonding performances, realizes high strength and toughness of a rock wool product and can be widely used for production of rock wool thermal-insulation fireproof materials.

Description

technical field [0001] The invention relates to a phenolic resin binder, its preparation method and its application in rock wool thermal insulation and fireproof materials. Background technique [0002] Rock wool is a fibrous loose material made of natural ore as the main raw material through high-temperature melting, centrifugal blowing, and cotton collection. Direct use will bring difficulties to construction. At the same time, when loose rock wool is used directly , its thermal insulation and hydrophobic performance indicators are reduced, so both at home and abroad are sprayed with an appropriate amount of atomized phenolic resin binder to heat and cure the rock wool during the fiber formation process. [0003] The quality of phenolic resin binder has a great impact on the quality of rock wool products. At the same time, the production cost of phenolic resin binder accounts for a relatively high proportion of the production cost of rock wool products. Therefore, improvin...
