The polyurea resin can enhance the toughness and strength of the glass magnesium board; the surface of the glass magnesium board is filled and leveled, so that the next working procedure is facilitated; meanwhile, toner or color paste can be added into the polyurea resin for color mixing, and the prepared polyurea resin glass magnesium board can be directly used as a printing substrate, so that the procedure of paint spraying is omitted, and the time and the labor are saved. The reinforcing ribs are formed on the back of the glass magnesium board, so that the glass magnesium board can be prevented from deforming, and concave holes in the back of the glass magnesium board can exhaust air when the board is installed.
Description
Technical Field
The utility model relates to a glass magnesium board, in particular to a glass magnesium board with polyurea resin sprayed on the surface.
Background
The magnesium wave plate has good fire resistance, light weight, good heat conducting property, good sound insulation effect, high stability, insect prevention and mildew prevention, and is widely used as a building partition wall, a suspended ceiling, a door plate and the like at present. However, the surface smoothness of the glass magnesium board is poor, and the strength and toughness of the glass magnesium board are poor compared with those of a plastic board, so that the requirements of the floor cannot be met.
The polyurea resin is an elastomer substance generated by the reaction of an isocyanate component and a resin component, has 100 percent of solid content, no solvent, no organic volatile matter, no toxicity, elasticity on the surface, no fear of scratch, water resistance, corrosion resistance and wear resistance, and is commonly used for repairing coatings and pavements at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a polyurea resin glass magnesium board is equipped with the polyurea resin layer on the top surface on glass magnesium board body layer, can strengthen the intensity and the toughness of glass magnesium board by a wide margin, fills up glass magnesium board surface simultaneously.
The utility model adopts the technical proposal that: the polyurea resin glass magnesium board comprises a glass magnesium board body layer and a polyurea resin layer which are arranged in sequence.
Preferably, the polyurea resin is a polyaspartate polyurea resin.
The polyurea resin can be blended with toner, color concentrate or color paste to color the polyurea resin. The glass magnesium board body layer is formed by adding a modifier, a light filler and a reinforcing material into a magnesium oxide, magnesium chloride and water ternary system, wherein the light filler is one or more of wood chips, perlite, talcum powder, silicon carbide, vermiculite and lime powder, and the reinforcing material is one or more of glass fiber cloth, carbon fiber cloth and non-woven fabric.
Preferably, the polyurea resin layer has a thickness of between 14 and 34 filaments.
Preferably, a plurality of reinforcing ribs are arranged on the bottom surface of the glass magnesium board body layer.
Preferably, the reinforcing ribs are distributed on the bottom surface of the glass magnesium board body layer in a strip or grid shape.
The preparation method of the polyurea resin glass magnesium board comprises the following steps:
A. adding a modifier, a light filler and a reinforcing material into a ternary system of magnesium oxide, magnesium chloride and water to prepare a glass magnesium board body;
B. pressing the bottom surface of the glass magnesium board body layer by using a metal board with a strip-shaped or grid-shaped protrusion on the surface to form reinforcing ribs distributed in a strip shape or a grid shape on the bottom surface of the glass magnesium board body;
C. and spraying a layer of polyurea resin on the top surface of the glass magnesium board body.
The utility model discloses set up one deck polyurea resin on glass magnesium board surface, polyurea resin can permeate into back flash drying fast, is netted the distribution with the part of glass magnesium board contact, can be better adhere to on the glass magnesium board. The polyurea resin can enhance the toughness and strength of the glass magnesium board; the surface of the glass magnesium board is filled and leveled, so that the next working procedure is facilitated; meanwhile, toner or color paste can be added into the polyurea resin for color mixing, and the prepared polyurea resin glass magnesium board can be directly used as a printing substrate, so that the procedure of paint spraying is omitted, and the time and the labor are saved. The reinforcing ribs are formed on the back of the glass magnesium board, so that the glass magnesium board can be prevented from deforming, and concave holes in the back of the glass magnesium board can exhaust air when the board is installed.
