Abstract
The invention discloses a water hyacinth and melamine-urea-formaldehyde resin composite material and a preparation method of a water hyacinth and melamine-urea-formaldehyde resin composite medium-density board. The water hyacinth and melamine-urea-formaldehyde resin composite material comprises 40-50 parts by weight of a melamine-urea-formaldehyde resin adhesive, 70-80 parts by weight of water hyacinth powder and 1-2 parts of ammonium chloride. The preparation method of the water hyacinth and melamine-urea-formaldehyde resin composite medium-density board comprises the following steps: pretreating water hyacinth, adding the pretreated water hyacinth into the prepared melamine-urea-formaldehyde resin adhesive, adding ammonium chloride which serves as a corresponding curing agent, and hot-pressing to form the water hyacinth and melamine-urea-formaldehyde resin composite medium-density board. By optimizing the preparation process of the melamine-urea-formaldehyde resin adhesive, the melamine-urea-formaldehyde resin adhesive which can be combined with the water hyacinth powder can be prepared. Particularly, methoxy polyethylene glycol which is added to the formula to serve as a surfactant can be combined with the water hyacinth powder and the melamine-urea-formaldehyde resin, so that methoxy polyethylene glycol can serve as an adhering medium to adhere the dried water hyacinth powder to the melamine-urea-formaldehyde resin adhesive tightly.
Description
Technical field
The present invention relates to field of compound material technology, is especially to provide a kind of Herba Eichhorniae-melamine urea-formaldehyde resin and is combined
The preparation method of material and its density board.
Background technology
On the one hand, China's forest tree resource is deficient, even more rare using the forest tree resource as sheet material.But annual production
Crop yield is huge, therefore and the agricultural wastes of generation are also large number of.So China's treatment in accordance with local conditions, set about studying with
These wastes of crops are that raw material develops nonwoodbased panel, enable resource that is originally discarded or dealing with improperly by effectively profit
Use.At this stage mainly by around to various agricultural byproducts such as cotton stalk, bagasse, bamboo wood, rice straw, Caulis et Folium Lini stalk or its
Probing into for his common Plant fiber's characteristic, further carries out the development of nonwoodbased panel.
1 bagasse
Because bagasse proportion is little, fiber quality is excellent, and obtained light weight board can reach higher intensity, with resistance to
The advantages such as water, fire resisting, antibiont corrosion, there is very strong plasticity, applicable many fields, therefore possess great market price
Value.But the sugar that fresh bagasse all can be remnants a small amount of, it is necessary to store reasonable time, but just can not can make residual sugar too long
Thoroughly natural fermentation and bagasse will not blackening.And have more than 1/3rd to be soft sugarcane marrow in sugarcane fiber, strictly do not remove
The Quality Down of material will seriously be caused, the pretreatment work of bagasse is increased；
2 bamboo woods
Although bamboo falls within one of forest reserves, but compared with trees, bamboo is the rank vegetation, and quantity will much surpass
Timber is crossed, abundant raw material can be provided for wood-based plate manufacture.Bamboo material surface is smooth, and intensity and comprcssive strength are high, but structure is not
Uniformly, easily damage by worms mouldy, validity period is short.If long-time carries larger load and can also result in the excessive situation of bamboo wood generation creep,
Material is set to be destroyed in itself.
3 Caulis et Folium Oryzaes
Caulis et Folium Oryzae has longitudinal resistance to tension that can be comparable with some timber, also only can be somewhat even across heat treatment
Reduce.Rice straw fiber distribution it is very uneven, integrated distribution inside straw, and top layer then by substantial amounts of sulfur dioxide,
The materials such as fats, mineral nitrogen are wrapped up, and together form smooth apolar surfaces layer, cause compressed straw slab to join intensity difference.This
The presence of a little materials can not only prevent the generation of chemical bond between rice straw internal hydroxyl groups and synthetic resin, but also can increase resin
The difficulty of solidification.
4 other
During with urea-formaldehyde glue as adhesive producing cotton stalk medium density fiberboard, resin added 12%, 180 DEG C of hot pressing temperature, hot pressing
The process conditions of time 15s/mm can produce the sheet material of strong mechanical performance, but the sheet material thickness swelling rate of 24 hours compared with
It is high.
As can be seen here, existing nonwoodbased panel has high cost, unstable properties, perishable, mechanical property low
Feature.
On the other hand, Herba Eichhorniae breeding is rapid, can disturb ecological stability, and pollutes.Some the anti-eliminating waters for adopting at present
The method of calabash it is more or less the drawbacks of all presence is certain, although such as chemical control effect is more certain, make on a large scale
With expense also costly, and it is most important be in the problem for producing a series of environmental and safety aspects.And adopt and directly beat
Although the original method dragged for does not result in counter productive, but needs a large amount of labour forces, and without any economic benefit conduct
It is difficult to ensure that very much in the case of motive force and the Herba Eichhorniae beyond capacity is salvaged in time.Develop Herba Eichhorniae to prepare
Product with certain function, to obtain corresponding income, be using market-oriented direction solve the pollution problem of Herba Eichhorniae into
To solve the task of top priority of this problem.
Rich cellulose in Herba Eichhorniae, the hardness of its cellulose is big, and modulus value is high, can use as structural material.But
The poor toughness of cellulose, shock resistance is weak, so to make if structural material, there is certain defect, and current Herba Eichhorniae exists
The enhancing of this respect performance yet there are no relevant report, how research and develop a kind of Herba Eichhorniae-resin compounded of excellent in mechanical performance
Material is to determine the Herba Eichhorniae whether key factor that can be utilized effectively.
