Problems solved by technology

[0005] To replace PVC, acrylic resin also needs to have the same film-forming properties and toughness as PVC. Therefore, it is also necessary to add a plasticizer with good compatibility with it. However, the current acrylic resin and TXIB, DOTP and other environmentally friendly plasticizers The compatibility is not good, and there is no relevant report about adding environmentally friendly plasticizers such as TXIB and DOTP to acrylic resin to improve its toughness and film-forming properties

Embodiment

[0026] 0.1 mass parts dispersant (polyvinyl alcohol) and 64.4 mass parts deionized water were stirred and mixed uniformly at room temperature, then the temperature was raised to 65°C; 34.67 mass parts monomers of the composition shown in Table 1, 0.55 mass parts initiator ( Azobisisobutyronitrile), 0.07 parts by mass of surfactant (sodium lauryl sulfate), 0.21 parts by mass of molecular weight regulator (n-dodecyl mercaptan), insulated and stirred for 8 hours, and the stirring speed was 450rpm. That is, the acrylic resin of the present invention is obtained.

Abstract

The invention discloses acrylic resin having an excellent compatibility with environment-friendly plasticizers. The acrylic resin is prepared by polymerizing the following monomers by weight percent: 40.0%-50.0% of methyl methacrylate, 30.0-50.0% of butyl methacrylate, 0-10.0% of isobutyl methacrylate, 3.0-15.0% of methyl acrylate, 0.2-2.0% of methacrylic acid, 0-10.0% of ethyl methacrylate and 0.2-2.0% of hydroxyethyl methylacrylate, wherein the sum of the weight percent of the monomers is 100%. The acrylic resin provided by the invention has the excellent compatibility with non-phthalate esters environment-friendly plasticizers and can be completely miscible with the environment-friendly plasticizers so as to form a transparent liquid and form a film; the film toughness reaches up to level 0T; the acrylic resin has the advantages of high stability, environmental protection, safety, no toxicity, and the like and can be used for replacing PVC.

Description

technical field [0001] The invention relates to an acrylic resin, in particular to an acrylic resin with good compatibility with an environment-friendly plasticizer, and belongs to the technical field of acrylic resin materials. Background technique [0002] PVC (polyvinyl chloride) is a widely used general-purpose plastic, mainly used in pipes, plates, fiber materials, membrane materials, plastisols and other fields. Among them, PVC plastisol is the main sealant for automobiles, which is about 1 / 3 of the adhesives for automobiles in my country. In recent years, as people pay more and more attention to environmental health, some problems caused by PVC have also been paid more and more attention by people. For example, the residual monomer vinyl chloride in PVC migrates out of the surface of the product over time, which will cause serious harm to human health. Great impact; the combustion product of PVC, dioxin, will seriously pollute the environment, have strong carcinogeni...
