Problems solved by technology

The price of polylactic acid is relatively high, and its price is about 2 to 3 times that of petroleum-based resins. The high price limits the promotion of PLA sheets. Therefore, it is necessary to provide a low-cost polylactic acid sheet for widespread promotion and greater play. Advantages of polylactic acid degradable

Embodiment Construction

[0034]In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail through specific examples below.

[0035] The following examples have no special instructions, and all raw materials can be obtained through commercial channels.

[0036] The present invention provides Embodiment 1-Embodiment 3, wherein the composition of each embodiment is shown in Table 1.

[0037] Table 1

[0038]

[0039] It can be seen from Table 1 that the degradable polylactic acid sheets with high plant fiber content provided in Examples 1-3 are prepared from plant fibers, polylactic acid, inorganic fillers, toughening agents, lubricants, chain extenders, hydrolysis-resistant agent, compatibilizer composition.

[0040] Among them, the polylactic acid is PLLA with a relative molecular weight of 100,000. The optical purity of L-polylactic acid is 98%-99.5%, and the melt flow index is 5-30g / ...

Abstract

The invention belongs to the technical field of building materials, and particularly discloses a degradable polylactic acid plate and a preparation method thereof. The plate is prepared from the following raw materials in parts by weight: 5-30 parts of polylactic acid, 60-80 parts of plant fibers, 5-30 parts of a modifying aid and 0-20 parts of inorganic filler, wherein the weight percentage of the plant fibers in the plate raw materials is 60-75%. According to the degradable polylactic acid plate with a high plant fiber content, the components are reasonably designed, the preparation processis improved, and the obtained plate is excellent in performance, uniform in texture and high in strength under the condition that the adding amount of the plant fibers is increased, and can be used asa building material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a degradable polylactic acid board with high plant fiber content, and also to a preparation method thereof. Background technique [0002] As a home decoration material, boards are favored by consumers because of their advantages such as not easy to deform, various colors, and easy disassembly and assembly. According to the source of materials, panels are generally divided into two categories: solid wood panels and wood-based panels. As the name suggests, the solid wood board is a wood board made of complete wood. It has the advantages of firmness, durability and natural texture. The maintenance cost is also too high, thus limiting the application of solid wood panels in decorative panels. Because wood-based panels can recycle scraps, their production costs are low. At present, they are widely used in various fields of decoration, and have formed a series of products ...
