[0039]The preparation method of the glass magnesium board includes the following steps:

[0040]Step S1: Put the prepared high-activity magnesium oxide into a ball mill for 30 minutes and grind it through a 180-mesh sieve for later use. Add pure water to the magnesium chloride to fully dissolve it into a solution and let it stand for 24 hours and mix with the high-activity magnesium oxide, then pour it into a mixer and stir evenly After adding plant fiber, filler, magnesite water resistant powder, and modified polyurethane, continue to stir to form a flour paste, the stirring speed is 400-500r / min, and the time is 20min;

[0041]Step S2: Pour the configured flour paste into the template of the forming machine. The forming machine is provided with two layers of low-alkali glass fiber cloth. The flour paste is placed between the upper and lower layers of low-alkali glass fiber cloth and is formed by roll forming. The molding temperature is controlled at 30℃, and the molding time is 25-28 ho...

Abstract

The invention discloses a glass magnesium board with a good sound insulation effect. The glass magnesium board is prepared from the following raw materials in parts by weight: 60-70 parts of high-activity magnesium oxide, 30-40 parts of magnesium chloride, 6-8 parts of alkali-resistant glass fiber cloth, 5-10 parts of plant fiber, 5-7 parts of magnesite water-resistant powder, 20-30 parts of filler and 20-30 parts of modified polyurethane. The glass magnesium board is prepared through the following steps of: material preparation; ingredient stirring; forming; and curing and edge cutting. In the process of synthesizing the glass magnesium board, the activity of the magnesium oxide has an important influence on the performance of the final glass magnesium board, so that the high-activity magnesium oxide is synthesized, and the polyurethane is subjected to graft modification by adopting organic silicon, and therefore, the obtained modified polyurethane combines the polyurethane and effective components in the glass magnesium board into a whole through a bonding effect, and sound insulation function of the glass magnesium board is enhanced while the waterproof performance and hardnessof the glass magnesium board are improved.

Description

Technical field[0001]The invention belongs to the field of functional materials, and specifically relates to a glass magnesium board with good sound insulation effect and a preparation method thereof.Background technique[0002]Glass magnesium plate (commonly known as magnesium oxide board) is made of a ternary system of magnesium oxide, magnesium chloride, and water through configuration and addition of magnesite water-resistant powder. It is a stable magnesia cementing material with medium alkaline glass fiber The net is a new type of non-combustible decorative material compounded with lightweight materials as fillers. Processed by special production technology, it has the characteristics of fireproof, waterproof, odorless, non-toxic, non-freezing, non-corrosive, non-cracking, unchanged, non-combustible, high strength and light weight, convenient construction, long service life, etc., among similar products in the country There are compound special properties. In the manufacturing p...
