Problems solved by technology

Due to the material characteristics of wood swelling and shrinking when wet, wood-based panels are prone to warping and deformation when used outdoors; when used as building templates, because the water in the concrete gradually penetrates into the boards, there is a static effect of the templates with the increase of moisture content. Defects of reduced flexural strength and static flexural modulus
[0003] my country is a big country in the production of textiles and garments. A large amount of fabric waste is produced every year. In people's daily life, a large amount of old clothes, sheets, bedding and other fabric products are discarded every year. This will not only cause environmental pollution, but also cause great waste

Embodiment 1

[0026] A regenerated fabric fiber plywood is characterized in that waste fabric regenerated fiber is used as a raw material, and a thermosetting adhesive is used in an amount of 20-25% of the weight of the raw material, and the plywood is made into a new plywood by hot pressing.

[0027] The specific implementation steps are as follows:

[0028] (1) Raw material sorting: Manually classify waste fabric waste and products according to pure cotton and chemical fiber, remove buttons, zippers and other sundries of waste fabric products, and remove oil stains;

[0029] (2) Recycled fabric fiber coil processing: using complete sets of equipment for non-woven fabric processing in the textile industry, the waste fabric is processed into flocculent fibers by a double-roller after being cut by a wire drawing machine, and processed into recycled fibers by carding, paving, and acupuncture. The fabric fiber coil has a thickness of 5-10mm, a width of 1-1.3m, and a length of 100-150m.

Embodiment 2

[0037]A regenerated fabric fiber plywood is characterized in that waste fabric regenerated fiber is used as a raw material, and a thermosetting adhesive is used in an amount of 20-25% of the weight of the raw material, and the plywood is made into a new plywood by hot pressing.

[0038] The specific implementation steps are as follows:

[0039] (1) Raw material sorting: manually sort waste fabric products and leftovers according to different thicknesses, remove buttons, zippers and other sundries of waste fabric products, remove oil stains, and cut old clothes into cloth pieces;

[0040] (2) Dipping: The amount of thermosetting adhesive used is 20-25% of the weight of raw materials. The adhesive uses urea-formaldehyde resin with a solid content of 45-48%. The volume ratio of adhesive to water is 1:0.7-0.9. Mix thoroughly in the glue tank, and soak the cloth of the same thickness in the glue tank.

[0041] (3) Blank assembly: Manually assemble the blanks on the paving workbenc...

Abstract

The invention relates to the manufacture for a regenerated knitting fiber laminated board. It sorted the material, removed impurities, processing the regenerated fiber rolling material, processing the waste fiber into flocculent reel, dipping and drying with adhesive of 20-25% of the material, using 45-48% formaldehyde-phenol resin dipping and drying the fiber reel, blank forming in compression ratio of 1: 1. 2, hot-press gluing in the temperature of 140deg.C+-5deg.C, pressure 30-35kg / cm2, keeping the temperature and pressure in 1min / mm, stereotyping and trimming. It can process the waste clothes directly. It is simple, strong in board strength, without deformation, low in cost.

Description

technical field [0001] The invention relates to an artificial board and a manufacturing method thereof, in particular to a regenerated fabric fiber plywood board and a manufacturing method thereof. Background technique [0002] At present, wood-based panels are made of wood, and the production process is complicated. my country's wood-based panel industry has developed rapidly in recent years. According to statistics, in 2003, the total output of my country's four major wood-based panel varieties (plywood, particleboard, fiberboard, and blockboard) had reached 45.53 million cubic meters, ranking second in the world. . Due to the rapid development of the wood-based panel industry requires a large amount of raw materials, the gap in wood supply is 100 million cubic meters according to the data, and the price of wood is rising rapidly, which brings great pressure to the cost control of wood-based panel products; therefore, raw materials for the wood-based panel industry Supply...
