Method for manufacturing microwave composite palm fiber cement plate

Abstract

The invention discloses a method for manufacturing a microwave composite palm fiber cement plate. The method comprises the following steps: 1) pretreating palm fiber under a microwave irradiation condition; 2) soaking the palm fiber obtained in the step 1) into a modification solution, and performing modification; 3) spraying cement slurry to the palm fiber obtained in the step 2); 4) uniformly laying the palm fiber obtained in the step 3 into a plate manufacturing mold; 5) overlapping 10-15 layers of molds of cloth obtained in the step 5) layer by layer, and performing pressing molding undermicrowave irradiation; and 6) removing the molds of different layers obtained in the step 5) so as to obtain 10-15 plates, and performing maintenance, so as to obtain the microwave modified inorganiccementing wood-based plate. With the combination of a microwave technique and a modification material, the palm fiber is pretreated, combination of cement with the palm fiber is implemented by using aspecific preparation method, the problem that a cement structure is damaged by the palm fiber can be finally solved, in addition, the strength of the composite plate is improved by effectively utilizing the property that the palm fiber is strong and tough, and application of the palm fiber is widened.

Description

technical field [0001] The invention relates to a method for manufacturing a microwave composite brown silk cement board, which belongs to the field of cement board preparation. Background technique [0002] As a traditional fiber material, brown silk is widely used in the weaving industry. The main material of traditional brooms and braided ropes is brown silk. However, the amount of brown silk used in light industrial products is relatively small, and the large amount of brown silk produced in Southeast Asia every year is far from being effectively utilized. In Southeast Asia, palm silk is similar to straw, and most of the fruits are burned after harvesting, causing a lot of pollution. [0003] In recent years, my country's housing and construction department has vigorously advocated prefabricated buildings, passive houses, energy-saving buildings, etc., which put forward many requirements for traditional building materials such as high strength, high precision, light wei...
