Abstract
The invention belongs to the technical field of artificial board preparation and particularly relates to a method of manufacturing a recoverable shaving board by polyamide. The method is characterized in that in the shaving board, the biodegradable polyamide is used as adhesive, and glutolin which is harmful to a human body is not used. The shaving board which is obtained by the method has the advantages that the intensity is high, the mechanical property is good, the waterproof performance is excellent, the environment-friendly effect is realized, the shaving board can be repeatedly pressed and reused, resources are saved, and the like; the manufacturing technological process is short, the resource utilization ratio is high, the input and consumption are low, and the operation is easy and simple.
Description
Technical field
The invention belongs to wood-based plate preparing technical field, specifically about a kind of polyamide for making the method for recyclable particieboard.
Background technology
Particieboard is the wood-based plate be made under the condition heated and pressurize after being mixed by the particles such as timber or other ligno-cellulosic materials and adhesive.Particieboard is not only for architectural engineering, and application is in daily life very extensive, and market demand is very large.Current particle boards to manufacturing field mainly uses glutol: pollopas, phenolic resins and melocol.But glutol can discharge formaldehyde gradually in the process used, and formaldehyde is a kind of toxic and harmful, not only has a strong impact on the healthy of people, also can cause serious pollution to surrounding enviroment simultaneously.
Release without toxic and harmful in polyamide use procedure, negative effect is not had to the physical and mental health of people and environment.Polyamide can be used for auto industry, transportation, machinery manufacturing industry, electric and electronic industry and articles for daily use etc.Amido link in polyamide makes polyamide have the structure similar with protein, can biodegradation.Use for laboratory polyamide broken powder in inventor place mixes with woody debris, be pressed into the high-quality particieboard with high strength, obtained particieboard not only has good mechanical property, and can recycle and repeatedly suppress, have no formaldehyde or the release of other poisonous and harmful volatile matters especially, adhesive therefor can be degraded at occurring in nature.
Summary of the invention
The present invention produces particieboard using a kind of polyamide as adhesive, has intensity high, and mechanical property is good, and water resistance is excellent, environmentally friendly, repeatedly can suppress recycling, and the advantage such as economize on resources.
Of the present invention described with a kind of polyamide for making the method for recyclable particieboard, concrete operation step is as follows:
Step a, pulverizer is utilized to break into powder polyamide used;
Step b, polyamide powder and woody debris to be fully uniformly mixed, to make polyamide powder be evenly distributed between all woody debris;
Send into hot press in step c, mould of the woody debris mixing polyamide powder being mated formation and carry out hot pressing;
Steps d, after hot pressing a period of time, after dropping to uniform temperature by mould take out, obtain after cooling a kind of polyamide make recyclable particieboard.
In step b, polyamide use amount is 5 ~ 30%.
The woody debris used in step b is wood shavings or wood chip or cavings or Wheat Straw or bagasse.
In step c, hot pressing temperature is 90 ~ 130oC.
In step c, hot pressing pressure is 1 ~ 10MPa.
In steps d, hot pressing time is 10 ~ 20min.
In steps d. be cooled to uniform temperature to be 80 oC and following.
Advantage of the present invention and innovative point are: 1. use polyamide as adhesive, the strength of shaving boards of production is high, and mechanical property is good, and water resistance is excellent, and non-volatility poisonous and harmful substance discharges, environment-protecting asepsis safety and sanitation.2. adhesive polyamide used connects with amido link, has the structure similar with protein, can biodegradation, environmentally friendly.3. this particieboard produced using polyamide as adhesive can be easy to broken at a certain temperature thus repeatedly suppress; such recycling avoids the waste of resource and the pressure to environment; be conducive to protection of the environment, economize on resources, be also conducive to economic sustainable development.
