Embodiment Construction

[0016] A composite square material used in building construction, comprising a plastic outer shell 1 and a multi-layer support body 2, the multi-layer support body 2 is fixedly arranged in the plastic outer shell 1, and the plastic outer shell 1 and the multi-layer support body 2 is a one-shot integral structure.

[0017] A composite beam manufacturing method used in building construction is:

[0018] Dry the recycled waste plastic products to remove water. Then, the waste wood products are processed into wood fibers with a length of 20 mm and a diameter of 1 mm. Mix the above two raw materials with 80% waste plastics and 20% wood fiber (the above percentages are percentages by weight), put them into a container and heat them to 180°C to melt, and then make plastic strips, and the temperature is controlled at 130°C . A plurality of waste plywoods are made into strips respectively, and the plurality of waste plywoods are glued and connected in sequence. The two plastic stri...

Abstract

A composite square material used in building operations comprises a plastic outer shell and a multi-layer bearing body. The composite square material is characterized in that the multi-layer bearing body is filled in the plastic outer shell and the plastic outer shell and multi-layer bearing body are both integral structures through one-step molding. The preparation method of the square material comprises the following steps: mixing 70-90% of waste plastic and 10-30% of wood fibre or bamboo fiber, placing the mixture in a container to heat to 210-180 DEG C and melt the mixture and preparing plastic strips; preparing the multi-layer bearing body by processing the waste wood products and bamboo to strips and then binding the strips to form an integral structure according to the set length, width and thickness; separately placing two plastic strips and the multi-layer bearing body in a trough section shaper and pressing to form the product with a hydraulic machine under the pressure of 20-50KN, wherein the multi-layer bearing body is arranged between the two plastic strips. The composite square material of the invention has low production cost, easy preparation, convenient construction and use, lower construction cost, good economic efficiency and significantly social efficiency.

Description

(1) Technical field: [0001] The invention relates to a building material, in particular to a composite square material made of waste plastics. (two) background technology: [0002] With the development of our country's economy, urban construction has become more and more developed, and various styles of buildings have sprung up, beautifying our living space. At present, due to the light weight of wood, easy sawing and planing, and convenient construction, square wood is generally used as formwork keel and back corrugated material for decoration engineering in construction engineering construction. However, massive felling of trees will inevitably aggravate the deterioration of the natural environment, and my country's per capita forest resources are only 20% of the world's average level. Forest resources are scarce, and the amount of harvesting is greater than the amount of production. This is really a disaster for China, which lacks forest resources. Since my country is a...
