Container bottom plate and preparation method thereof

Abstract

The invention discloses a container bottom plate, which is composed of a wood plastic composite material core board and a continuous glass fiber reinforcement surface layer which are adhered together, wherein the wood plastic composite material core board comprises the following raw material components in percentage by mass: 20-35 percent of polyolefin resin, 40-70 percent of plant fiber powder, 0-30 percent of reinforcing filler, 2-5 percent of compatilizer A and 0-1 percent of additive; and the continuous glass fiber reinforcement surface layer comprises the following raw material components in percentage by mass: 20-50 percent of synthetic resin, 45-70 percent of glass fiber, 0-10 percent of compatilizer B, 0-10 percent of fire retardant and 0-2 percent of other aids. The waste wood fibers and synthetic resin serve as raw materials, and the performance of the bottom plate is reinforced due to the surface glass fiber, the resources are saved and the cost is reduced on the basis that the application requirements are met.

Description

technical field [0001] The invention relates to the field of floor technology, in particular to a glass fiber-reinforced wood-plastic composite container bottom plate and a preparation method thereof. Background technique [0002] The container floor is the floor installed at the bottom of the container, which can carry the weight of the object and fix the cargo. In order to reduce the transportation weight and facilitate the fixing of goods, wooden bottom boards are often used. However, due to the increasing scarcity of forest resources and less and less wood resources, the use of solid wood floor boards is greatly restricted and is gradually replaced by plywood. Chinese patent (CN02134300.4) provides a kind of plywood for container floor which is made of eucalyptus veneer and birch, poplar, larch and other veneers glued together. Chinese patent (CN 03152841.4) provides a bottom plate for containers whose surface layer is made of bamboo veneer and core layer of fast-growi...
