Waste plant fiber comprehensive utilization technique, will be one of technology that 21 century every country is given priority to.It is discarded to plant
Fibres enhancing polymer matrix composite is Novel environment-friendlymaterial material, and its reasonable utilization to environmental protection and the forest reserves will rise
To very positive effect.This cost of material is low, recyclable recycling, progressively substitutes timber, plastics, steel, can
Energy resource consumption is reduced, the effect of energy-conservation is reached.
But, because waste plant fiber is mainly by cellulose, hemicellulose, lignin and other are a small amount of into packet
Into natural material, and in the main component of cellulose, hemicellulose and lignin contain substantial amounts of polar hydroxyl groups and phenolic hydroxyl group
Functional group, therefore have very strong chemical polarity.And the plastics used are mainly the non-polar materials such as PP, PE.Therefore it is multiple in wood moulding
, it is necessary to solve the compatibility of polarity wood materials and non-polar plastic in condensation material recombination process；At present, mainly producing
Used in journey and formaldehyde material is used in phenolic resin or urea-formaldehyde resin adhesive, the type adhesive, it is impossible to reach wanting for environmental protection
Ask, while the type adhesive can not play the effect of coupling agent.
The content of the invention
Based on this, a kind of adhesive is provided it is an object of the invention to overcome above-mentioned the deficiencies in the prior art part, should
Adhesive does not contain formaldehyde, plasticizer etc. to environmentally hazardous substance, and the adhesive is by string by hydrogen bond action
It is bonded together, while the adhesive can play coupling agent effect in composite.
To achieve the above object, the technical solution used in the present invention is：A kind of adhesive, includes the group of following parts by weight
Point：40~60 parts of ethylene-vinyl acetate copolymer, 30~40 parts of tackifying resin, 10~20 parts of polymer coupler, antioxidant

Preferably, in the ethylene-vinyl acetate copolymer, the weight/mass percentage composition of vinyl acetate is 26%~30%.
Preferably, the ethylene-vinyl acetate copolymer is 20~60g/10min in 190 DEG C of melt index, above-mentioned common
The melt index of polymers, be conducive to PUR sprays uniformity on string.
Preferably, the density of the ethylene-vinyl acetate copolymer is 0.92~0.96g/cm3。
The present invention also provides a kind of preparation method of above-mentioned adhesive, comprises the following steps：
(1) each component is added in reactor, warming while stirring obtains homogeneous material to 140 DEG C~190 DEG C；
(2) homogeneous material obtained by step (1) is subjected to extrusion molding, produces the adhesive.
Preferably, in the step (1), the speed of stirring is 20~30r/min, and the time of stirring is 30~60min.On
Mixing speed and mixing time are stated, material mixing can be made more uniform.
Preferably, the extrusion molding in step (2) is carried out by double screw extruder, described twin-screw feeding section, pressure
The temperature of contracting section, homogenizing zone and mouth mold is controlled as 100 DEG C, 130 DEG C, 160 DEG C, 160 DEG C.
Meanwhile, the present invention also provides a kind of application of above-mentioned adhesive in string.Strengthen in string and polymerize
During thing composite, string is bonded together by the adhesive by hydrogen bond action, while the adhesive is in composite
It is interior to play coupling agent effect.
Secondly, the present invention provides a kind of preparation method of string, comprises the following steps：
(1) chopped string is put into mixing plant and be stirred, while spraying above-mentioned adhesive, pre-processed
String, wherein, the consumption of the adhesive is the 20%~50% of chopped string quality；
(2) preprocessing plant fibre for obtaining step (1) carries out hot forming, cooling, obtains vegetable fibre board；
(3) vegetable fibre board for obtaining step (2) carries out punch forming, obtains a diameter of 3~9mm string circle
Piece, as described string.
It is short that chopped string in the step (1) includes but is not limited to sisal hemp, jute, ramie, cotton, Wheat Straw etc.
Cut plant fiber.
Preferably, in the step (1), the speed of stirring is 30~50r/min, and the time of stirring is 5~10 minutes.
Preferably, in the step (2), the thickness of vegetable fibre board is 2mm~4mm.Use this thickness fiberboard system
The appearance and size of standby plant fiber particle is suitable with plastic grain size, beneficial to the blanking of material in process.
Preferably, in the step (2), hot-forming temperature is 160 DEG C~180 DEG C, hot-forming time for 5~
10 minutes, the temperature of cooling was 20 DEG C~30 DEG C, and the time of cooling is 5~10 minutes.
The present invention also provides the string that a kind of above-mentioned preparation method is prepared.The string energy direct quantitative
