Abstract
The invention discloses a novel plastic compatibilizer. The compatibilizer comprises, by weight, 20-40 parts of methyl methacrylate, 20-40 parts of butyl acrylate, 30-50 parts of glycidyl methacrylate and 25-45 parts of vinyl acetate. A small dosage of the novel plastic compatibilizer can obviously improve the tensile strength and the impact strength of a blend and enhances the interface bonding strenth between a plastic and wood fibers.
Description
Technical field
The present invention relates to chemical science field, refer more particularly to a kind of novel plastic expanding material and production method thereof.
Background technology
Wood plastic composite (wood plastic composites) is that a certain proportion of xylon is made it to a kind of type material being combined into thermoplastic polymer or other materials through pre-treatment, is also called WPC for short.Manufacture WPC and do not need high-quality timber resources, the waste woods such as logging residue, wood machining residues of take are main raw material, and used in large quantities the waste plastic reclaiming, to alleviating timber resources pressure and solving plastic pollution problem, played vital role.In wood plastic composite preparation, need to capture a large amount of technical barriers, wherein interface compatibility is the focus of wood plastic composite research always.Wooden material surface as strongthener contains a large amount of hydroxyls, has polarity and water-absorbent; The thermoplastic polymer adopting is mainly PE, PP, PS, PVC etc., and the surface of these polymkeric substance is generally nonpolar or polarity is very little.Directly wood powder and plastic blend can be caused to the generation of weak interface, interface interaction is little, and mechanical property is lower, therefore improves the research emphasis that interface gluing is blending and modifying always.Wood plastic composite need to solve the problem that how to make to have between the surperficial and hydrophobic non-polar plastic basal body interface of hydrophilic polarity xylon good consistency, for this class blend, conventionally need add suitable expanding material to increase two-phase interface gluing power to carry out effective stress transmission, thereby make to reach between the upper layer of xylon and the upper layer of plastic substrate the fusion of molecular level, form than the better advanced composite material of original single-material performance.At present the expanding material of most study is graft copolymer, and maleic anhydride stem grafting polyolefin is that the research difficulty of expanding material is larger and using the segmented copolymer with suitable chemical structure as wooden plastomer.Now study a kind of vinyl silanes-acrylate-glycidyl methacrylate copolymer, it is the agent of a kind of novel triblock copolymer compatibilization and toughening, amino in epoxide group wherein and the hydroxyl in wood powder, carboxyl (-COOH) or coupling agent interacts can significantly strengthen the bonding between expanding material molecule and wood powder fiber, and the nonpolar end group of expanding material molecule is close with PE structure, there is good consistency.
