preparation example Construction

[0014] The preparation method of molded fiber-reinforced polymer artificial marble comprises the following steps:

[0015] (1) Molding compound preparation: Weigh unsaturated polyester resin, curing agent, thickener, internal release agent and filler according to the above ratio, mix them evenly, and then add glass fiber and artificial color particles to make it Mix well, then knead into molding compound. Among them, the artificial color particles are cast from unsaturated polyester resin, methyl ethyl ketone peroxide, cobalt isooctanoate, calcium carbonate and pigments, and are crushed into particles with a diameter of 1 to 5 mm after solidification.

[0016] (2) Thickening: place the prepared molding compound to thicken, give full play to the thickening effect, and obtain a thickened molding compound.

[0017] (3) Heat the mold to 110-150°C and apply an external mold release agent, then put the thickened molding compound into the mold,

[0018] (4) Close the mold, molding ...

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a molded fiber-reinforced polymer artificial marble and a manufacturing method thereof. Background technique [0002] As a substitute for natural marble, artificial marble has been widely used in the manufacture of sanitary ware and The field of architectural decoration. At present, most of the artificial marble products sold on the market are molded by casting method with unsaturated polyester resin and acrylic resin. Artificial marble products formed by casting method are processed by imitating the surface texture of natural marble. They have the mechanism characteristics similar to marble, and are better than natural marble in terms of hardness, gloss and wear resistance. However, this artificial marble product also has disadvantages such as low strength, poor bending resistance, and easy deformation. Due to the use of casting methods, it lacks mass productivity ...
