Modified nanocellulose whisker/epoxy resin adhesive as well as preparation method and application thereof

Abstract

The invention relates to an adhesive, and discloses a modified nanocellulose whisker / epoxy resin adhesive, a preparation method and application thereof, the modified nanocellulose whisker / epoxy resin adhesive comprises a component A and a component B which are independently packaged, the component A comprises 26-68 parts by mass of epoxy resin, the component B comprises 10-35 parts by mass of an adhesive fixing agent and 2-5 parts by mass of a catalyst, and the adhesive fixing agent comprises oxidized modified cellulose whiskers; the modified cellulose whisker is used as a filler, so that the toughness of the adhesive is remarkably enhanced, and the physical properties of the bonding material are enhanced; the modified cellulose whisker is used as a curing agent of the epoxy resin, so that the activation energy during curing of the epoxy resin is remarkably reduced, and the energy consumption required during production is reduced; wood waste materials in the processing process are processed into cellulose fibers, then the cellulose fibers are subjected to oxidation modification and prepared into modified cellulose whiskers, and finally epoxy resin, the modified cellulose whiskers and a catalyst are mixed to prepare the adhesive, so that the effect of recycling waste is achieved, and the utilization rate of raw materials is increased.

Description

technical field [0001] The invention relates to an adhesive, in particular to a modified nano-cellulose whisker / epoxy resin adhesive, a preparation method and an application thereof. Background technique [0002] In recent years, skateboards have become a popular sports equipment for young people. It provides users with functions such as travel and sports. The structure of skateboards includes skateboard decks, skateboard bridges, and pulleys. Common skateboard deck materials are glued Wooden boards, plastics, carbon fiber and composite boards, among which plywood is the most recognized material by users, and plywood is also the most common skateboard surface material at present. [0003] For example, the publication number CN112165976A provides a board surface for a skateboard and a skateboard with the board surface for a skateboard, which can make the front and rear wheels stably contact the road surface with uneven three-dimensional shape while ensuring the usability and ...

Problems solved by technology

[0005] In the prior art, when the plywood is used, its toughness is lower than that of other materials. After the user uses it for a long time and performs fancy exercises, it is easy to have a decrease in toughness, which will cause the surface of the skateboard to break and the texture will decrease. Therefore, how to improve the toughness of the skateboard surface and increase the durability of the skateboard surface has become the research focus of various manufacturers; the applicant found in production practice that a large number of wood scraps will appear when making the skateboard surface, and these wood scraps Often treated as waste, the applicant further processed these wood scraps to improve the toughness of the skateboard surface
