Problems solved by technology

However, high polymer is a typical organic substance, and its structure is mainly composed of hydrocarbons, while montmorillonite is more of metal compounds and metal elements, and the polarity between the two is very different, so the difference in structure The resulting poor compatibility is a problem that cannot be ignored. It usually leads to phase separation and agglomeration of the final prepared composite material containing polyethylene and montmorillonite, which greatly affects the furniture composite material after granulation. The uniformity of the blending of the various components contained in it leads to a significant decrease in mechanical properties

preparation example 1

[0036]The preparation method of the acrylamide 1 grafted with polyethylene glycol monomethyl ether is as follows: in the reactor, 0.1mol of polyethylene glycol monomethyl ether (wherein, the number of repeating units of polyethylene glycol monomethyl ether is 5), mix with 1mol of acrylamide, then add 20wt% deionized water whose mass is polyethylene glycol monomethyl ether and stir evenly; then heat up to 70°C, add 0.1wt% of polyethylene glycol monomethyl ether Ammonium persulfate and 0.1wt% sodium bisulfite were used as catalysts to react for 3 hours to obtain acrylamide 1 grafted with polyethylene glycol monomethyl ether.

preparation example 2

[0038] The preparation method of the acrylamide 2 grafted with polyethylene glycol monomethyl ether is as follows: in the reactor, the polyethylene glycol monomethyl ether of 0.3mol (wherein, the repeating unit number of polyethylene glycol monomethyl ether is 10), mix with 1mol of acrylamide, then add 40wt% deionized water whose mass is polyethylene glycol monomethyl ether and stir evenly; then heat up to 90°C, add 0.3wt% of polyethylene glycol monomethyl ether Ammonium persulfate and 0.3wt% sodium bisulfite were used as catalysts to react for 5 hours to obtain acrylamide 2 grafted with polyethylene glycol monomethyl ether.

preparation example 3

[0040] The preparation method of the acrylamide 3 grafted with polyethylene glycol monomethyl ether is as follows: in the reactor, the polyethylene glycol monomethyl ether of 0.05mol (wherein, the repeating unit number of polyethylene glycol monomethyl ether is 7), mix with 1mol of acrylamide, then add 30wt% deionized water whose mass is polyethylene glycol monomethyl ether and stir evenly; then heat up to 80°C, add 0.2wt% of polyethylene glycol monomethyl ether Ammonium persulfate and 0.2wt% sodium bisulfite were used as catalysts to react for 5 hours to obtain acrylamide 3 grafted with polyethylene glycol monomethyl ether.

Abstract

The invention relates to a modified montmorillonite reinforced polyethylene composite material. The composite material is prepared from the following raw materials: polyethylene, montmorillonite, polyalcohol monoether grafted acrylamide, acrylamide and an initiator. The polyalcohol monoether grafted acrylamide is prepared from polyhydric alcohol monoether and acrylamide. In the composite materialcontaining the polyalcohol monoether grafted acrylamide branched chain, the compatibility of each component and montmorillonite is greatly improved, and the compatilizer is matched, so that the uniformity and the compatibility of the composite material can reach stable and excellent degrees, and the mechanical property and the toughness of the composite material are greatly improved. The inventionalso relates to a preparation method and application of the modified montmorillonite reinforced polyethylene composite material as a furniture board.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a composite material of modified montmorillonite reinforced polyethylene and its application in furniture. Background technique [0002] Polyethylene is the most widely used general-purpose plastic due to its cheap price, wide range of sources, and mature preparation methods. It is well known that polyethylene articles are widely used in various fields. However, polyethylene has poor toughness, and it is usually necessary to improve its toughness to make polyethylene have more excellent mechanical properties and weather resistance. It is a commonly used method to improve the mechanical properties and weather resistance of polyethylene by composite physical blending with inorganic fillers. And montmorillonite, as a commonly used inorganic filler, has a relatively ideal effect after blending with polyethylene, which is also known (Yuan Daosheng, master's dissertatio...
