High-toughness waterproof base plate and preparation method thereof

Abstract

The invention discloses a high-toughness waterproof base plate which comprises a glass magnesium plate base material layer, a toughening layer and a waterproof coating layer coating the surface of thetoughening layer, wherein the toughening layer is adhered to the surface of the magnesium plate base material layer through an adhesive; the toughening layer is made of a high-toughness polystyrene composite material; sequentially adding sodium bicarbonate and sodium oleate into a three-neck flask filled with deionized water, and carrying out stirring at a constant speed of 100-120 r / min until the particles are completely dispersed; and then adding styrene and divinyl benzene, carrying out heating in a water bath at 55-60 DEG C, carrying out stirring for 2 hours at a rotating speed of 240 r / min, and demulsifying, washing and drying the prepared particles to prepare particles for filling. The invention further discloses a preparation method of the high-toughness waterproof base plate. Thebutadiene rubber can be used as an elastomer to be blended to endow the finally prepared polystyrene with excellent toughness, so that the prepared polystyrene composite material has excellent toughness, and the effect of toughening the floor is achieved.

Description

technical field [0001] The invention belongs to the technical field of waterproof board preparation, in particular to a high-toughness waterproof board material and a preparation method thereof. Background technique [0002] The glass magnesium board is made of magnesium forming agent, glass fiber mesh cloth, filler, etc., through mechanical rolling, and is mainly used for indoor non-load-bearing walls and ceilings, as well as substrates for various decorative panels. The glass magnesium board in the prior art usually uses magnesium oxide and magnesium chloride as forming agents. In order to make the magnesium fully and quickly condense, the content of magnesium chloride should not be too low, otherwise the purpose of making the magnesium fully and quickly condense cannot be achieved, and when magnesium chloride When the content of chlorine ion is in line with the purpose of making magnesium fully and quickly condensed, the content of chloride ion is too high, which will eas...

Problems solved by technology

The glass magnesium boards in the prior art usually use magnesium oxide and magnesium chloride as forming agents. In order to make the magnesium fully and quickly condense, the content of magnesium chloride should not be too low, otherwise the purpose of making the magnesium fully and quickly condense cannot be achieved, and when magnesium chloride When the content of chlorine ion is in line with the purpose of making magnesium fully and quickly condensed, the content of chloride ion is too high, which will easily cause the board to absorb moisture and return to halogen

Not only that, the glass magnesium boards in the prior art are difficult to meet the requirements of national or industry standards in terms of flexural strength, impact strength, dry shrinkage rate, wet expansion rate, screw holding force, and non-combustibility at the same time, so that the limit The use of glass magnesium board in actual production
