Technical field
The present invention relates to composite floor field, and in particular to a kind of modified rubber powder-wood composite for mute floor board
The preparation method of material.
Background technology
In recent years, with the continuous development of economy, and building trade, the development of house ornamentation industry, decorations building materials and
Upholstery material rapid growth.Timber floor is a kind of important indoor decorating and refurnishing materials, possesses huge market potential.With
The improvement of people's living standards, people increasingly pay attention to life and ecological environment, but Global Forests resource is increasingly reduced, with
The shortage of timber resources, the outstanding advantage of solid wooden compound floor is got the nod rapidly in production and consumption field, and industry is able to
Flourish, therefore the requirement of the performance of the solid wooden compound floor to being widely used as interior decoration is more and more stricter.
The content of the invention
The present invention solves the technical problem of provide a kind of modified rubber powder-wood composite material for mute floor board
The preparation method of material, according to the technique prepare composite floor board mechanical property it is good, fire resistance is good, thermal stability is good.
The technical problems to be solved by the invention are realized using following technical scheme：
The preparation method of a kind of modified rubber powder-Wood composite material for mute floor board, it is characterised in that according to the following steps
Carry out：
A. waste rubber powder surface modification treatment：
By 50-60 parts by weight junked tires mechanical crushing, 60-80 mesh sieves are crossed, obtain waste rubber powder；
Distilled water is added into ethanol, is made into the solution that alcohol content is 90-95%, it is 4-6 to add second acid for adjusting pH, and stirring is lower to be added
Enter 1-2 parts by weight silane couplers, hydrolyze 5-10min, it is uniformly sprayed at rubber powder surface, is sufficiently mixed；In 500-
5-10min is handled under 700W microwaves, is soaked with sodium hydroxide solution, is warming up to 50-60 DEG C of stirring 20-30min；Then in 80-
4-6h is dried in 90 DEG C of baking ovens, produces modified rubber powder；
B. coupling modifier microcrystalline white mica powder：
20-30 parts by weight microcrystalline white mica powder is dried into 2-4h at 90-100 DEG C, put into homogenizer, adds 0.5-1
Parts by weight KH550, mixing modification 10-20min, obtains modification of microcrystalline muscovite；
C. 40-50 parts by weight wood wool is dried at 90-110 DEG C, is well mixed with resulting material in a, b, obtains premix：Will
In isocyanate adhesive input variable-ratio drum-type glue mixer, glue mixing is carried out, acetone is added and is diluted, then premix is entered
Row glue spraying；Using single layer structure, slab is mated formation by hand；Then precompressed 5- is carried out under unit pressure 1-2 MPa
10min；At unit pressure 3-4MPa, 140-170 DEG C of platen temperature, hot-pressing processing 10-15min；Cooling, displays 1-2d, sand
Light processing, obtain required composite.
Wherein, silane coupler described in step a is Si69, concentration of sodium hydroxide solution 40-50%.Described in step b
Mixing speed is 5000-6000r/min.The addition of acetone described in step c be isocyanate adhesive 4-6%, resin added
For 6-10%.
The present invention reaction mechanism and have the beneficial effect that：
First waste rubber powder is handled with silane coupler, increases the hydroxy number on its surface, strengthens its polarity, is improved multiple
The mechanical property of condensation material；Microwave modification rubber powder is used again, enhances the activity on rubber powder surface, can be with wooden plane after microwave modification
Flower-shape combines into close, and microwave makes rubber powder surface oh group occur, is advantageous to the combination between timber；Finally to rubber
Rubber powder uses sodium hydroxide solution immersion treatment, by alkali process lumber fibre can be promoted preferably to be combined with rubber powder.
The presence of a large amount of rubber grains, makes composite have relatively low intrinsic frequency and higher damping ratio；Due to multiple
Each order frequency spacing of condensation material is smaller, easily produces resonance, has given full play to the function of rubber grain damping energy-absorbing, improved material
Expect overall shock-absorbing denoising function.
Microcrystalline white mica powder is a kind of inorganic rigid particle with high intensity, the excellent properties such as heat-resisting, weather-proof, using its as
Filler, using dry method modification technology, after carrying out modification to its surface with Silane coupling agent KH550, it can be evenly distributed in
In PVC matrix, interface binding power between the two and compatibility are enhanced；Form effective stress and transmit point, improve compound
The mechanical property of material, meanwhile, the heat endurance and heat resistance of material are improved, has delayed material aging.
Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Specific embodiment is closed, the present invention is expanded on further.
