Abstract
The invention provides a performed polymer of an acrylic-based resin which is a compound composed of methyl methacrylate, polymethyl methacrylate, methacrylic acid, butyl acrylate and an acrylic ester assistant crosslinking accelerating agent with a polyfunctional group. The preformed polymer can be polymerized to form an atactic copolymer by curing at room temperature and the copolymer maintains or improves the physical chemical properties of the conventional acrylic-based resin. The preformed polymer can be polymerized at room temperature and has simple production technology and processing equipment and low energy consumption. Meanwhile, the production costs can be obviously reduced. The performed polymer is mainly applied to artificial marble products.
Description
Technical field
The present invention relates to the performed polymer of acrylic resin, specifically, relate to the performed polymer that is used to make artificial marmorean room temperature curing type acrylic resin.
Background technology
Acrylic is the transliteration of vinylformic acid (Acrylic), and the acrylic resin refers to acrylic resin, is the superpolymer of esters of acrylic acid.
Domestic existing glass fiber reinforced plastics product, artificial marble, the plastics that are used to make sanitary equipment, artwork mostly are unsaturated polyester (UP).Though the UP resin is fast setting at room temperature,,, use the UP resin must make environmental degradation in a large number, and wherein contained toxic substance also can impair HUMAN HEALTH so be difficult to recycle because of it can not post forming.
The acrylic resin has good comprehensive performances, and helps environment protection, is the preferred material that substitutes unsaturated polyester, but because of it adopts heat or light initiation system usually, so the polymeric time is long, equipment used is complicated, energy consumption is big, processing difficulties.These effects limit the popularization of acrylic resin.Therefore, polymeric acrylic resin prepolymer at room temperature appears in the expectation of present technique field.
Summary of the invention
The objective of the invention is to overcome the deficiency of conventional heat or light-initiated acrylic resin, provide a kind of process easy, the performed polymer of the acrylic resin of ambient temperature curable.
In order to realize purpose of the present invention, the invention provides a kind of performed polymer that is used to make artificial marmorean room temperature curing type acrylic resin, press performed polymer weight percent meter (down with), it by methyl methacrylate 47.5～83.9%, poly-methylpropanoic acid methyl esters 10～25%, methacrylic acid 4～10%, butyl acrylate 1～10%, help crosslinked accelerator 1～7% to constitute.This performed polymer can aggregate into atactic copolymer in room temperature under the effect of initiator and promotor.
It is described that to help crosslinked accelerator be the compound that contains multi-functional esters of acrylic acid; Initiator is a methylethyl ketone peroxide; Promotor is trivalent vanadium organic synthesis thing.
The Barcol hardness of the polymkeric substance that is polymerized by this performed polymer〉60, flexural strength 40Mpa, bending elastic modulus 6500Mpa, impelling strength 〉=4KJ/m
2
Methyl methacrylate in above-mentioned room temperature curing type acrylic resin prepolymer of the present invention is the cross-linking monomer in this performed polymer.
Described polymethylmethacrylate is used to regulate the viscosity of performed polymer.
Described methacrylic acid is a comonomer, is used to improve curing speed, increases the hardness of multipolymer.
Described butyl acrylate is a comonomer, is used to improve the toughness of this multipolymer.
Described to help crosslinked accelerator be the compound that contains multi-functional esters of acrylic acid, for example, produced by fairy house welfare inorganic chemical industry factory, and model is the crosslinked accelerator of helping of XF-203 type.
The initiator that described prepolymer is suitable for is an organo-peroxide, preferred methylethyl ketone peroxide; Promotor is trivalent vanadium organic synthesis body, and for example, the model of being produced by fairy house county welfare inorganic chemical industry factory is an XJ-B type trivalent vanadium promotor.
The manufacturing process of acrylic resin prepolymer of the present invention is as follows:
By weight percentage, prepare methyl methacrylate, polymethylmethacrylate, methacrylic acid, butyl acrylate, contain multi-functional acrylate and help crosslinked accelerator;
Described polymethylmethacrylate is added in the described methyl methacrylate gradually with stirring, entirely treat that it is molten;
Add methacrylic acid and butyl acrylate more respectively, stir;
Adding at last contains multi-functional acrylate and helps crosslinked accelerator, and stirring gets final product.
Embodiment
The invention is further illustrated by the following examples, so that to the understanding of technical scheme of the present invention and advantage thereof, better effects if, but described embodiment only is used to illustrate the present invention rather than restriction the present invention.
Embodiment 1 (being applicable to that resin and filling aluminium hydrate are the goods of 1:2)
19Kg polymethylmethacrylate (purity 〉=99.9%) is slowly added in the 64Kg methyl methacrylate (purity 〉=99.9%), treat described polymethylmethacrylate complete molten after, add 10Kg methacrylic acid, 3Kg butyl acrylate, 4Kg respectively and help crosslinked accelerator XF-203 (production of fairy house county welfare inorganic chemical industry factory).The said mixture stirring was got final product in 10 minutes.
Embodiment 2 (being applicable to that resin and filling aluminium hydrate are the goods of 1:1.5)
20Kg polymethylmethacrylate (purity 〉=99.9%) is slowly added in the 64Kg methyl methacrylate (purity 〉=99.9%), treat described polymethylmethacrylate complete molten after, add 8Kg methacrylic acid, 2Kg butyl acrylate, 5Kg respectively and help crosslinked accelerator XF-203 (production of fairy house county welfare inorganic chemical industry factory).The said mixture stirring was got final product in 10 minutes.
Acrylic performed polymer of the present invention is because of can at room temperature solidifying, so compare with the conventional acrylic resin of thermal-initiated polymerization, polymerization technique and equipment used are simplified, and energy consumption is low, thereby manufacturing cost significantly reduces.The performance of the artificial marble products made from acrylic performed polymer of the present invention satisfies the regulation of JC-908-2002 standard fully simultaneously.
