Acrylic solid surface material for artificial marble and preparation method of acrylic solid surface material

Abstract

The invention provides an acrylic solid surface material for an artificial marble. The acrylic solid surface material is prepared from the following raw materials in parts by weight: 100 parts of methyl methacrylate, 1-25 parts of a methacrylic acid functional monomer, 0.01-0.1 part of a polymerization initiator, 150-250 parts of a filler, 0.1-5 parts of a pigment, 0.5-15 parts of an acrylate cross-linking agent and 0.1-3 parts of a curing agent. The invention further provides a preparation method of the acrylic solid surface material. The methacrylic acid functional monomer is introduced into acrylic solid surface material resin, so that the mechanical property of the acrylic solid surface material is effectively improved, the impact strength is doubled in comparison with that of a traditional technology and can reach about 6.7KJ / cm<2> and the bending strength is also obviously improved and can at least reach 66MPa; the application field of the solid surface material is expanded; and the changing requirements of the market are met.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to an acrylic solid surface material of artificial marble and a preparation method thereof. Background technique [0002] The production of acrylic solid surface artificial marble has a history of more than 20 years. The publicly reported technology is to mix acrylic sheets (MMA) with fillers, add coupling agents and initiators, stir to make a slurry, and then pour it into a mold. 65 The polymerization reaction was carried out at ℃ for 3 hours, and the reaction was continued in an oven at 120℃ for 2 hours to obtain an acrylic solid surface material. [0003] The mechanical properties of the plate prepared by the above process are relatively low: the impact strength is 3.4KJ / cm2, and the bending strength is 48MPa. Contents of the invention [0004] In view of this, the object of the present invention is to provide an acrylic solid surface material of artificial marble, wh...
