Description
Technical field
The present invention relates to a kind of smooth glue of polyurethane wood, especially a kind of smooth use of the polyurethane wood of strong adaptability
Glue and preparation method thereof belongs to adhesive technology field.
Background technique
With the implementation of the worldwide forest reserves sharply reduced with China Natural Forest Conservation Programme journey, small timber is spelled big
Plate requires the adhesive strength of adhesive and the durable performances such as weather-proof to be better than timber itself.Adhesive dosage number, oneself become weighing apparatus
Measure the mark of timber industry state-of-art.The wood adhesive of past people is mostly using formaldehyde as the ureaformaldehyde of primary raw material
Resin, phenolic resin and melamine resin, but since free formaldehyde exists, it can be gradually to week during product use
Emitting formaldehyde gas is enclosed, environmental pollution is caused.Wood working industry oneself start to turn one's attention to the poly- ammonia of novel environment-friendly adhesive
Ester gum, to reduce the pollution to environment.The single-component mist-solidifying polyurethane adhesive that woodworking uses is liquid,
It uses at room temperature, adhesive strength height, flexibility and water-tolerant, and can be with many non-wood substrate (such as textile fabric, metal, modelings
Material, rubber etc.) bonding, and also dry, wet strength that monocomponent polyurethane adhesive is shown in testing are better than phenolic aldehyde
Adhesive.
Timber used on the market is smooth at present uses there are mainly two types of glue: one is hot melt adhesive resistant to high temperature, and one is low
The polyurethane adhesive at end.Hot melt adhesive bonding is that hot melt adhesive is melted by heating power using fuse machine, and the glue after melten gel becomes a kind of liquid
Body is sent in a manner of spraying, the defeated, extruding of tank etc. and is glued by the trunnion and spray gun of hot melt adhesive machine or other hot melt gluing equipments
Object surface is closed, just completes bonding after a period of time hot melt adhesive is cooling, it can be by the feedstock property of itself to universal bottom
Material is bonded, and has certain adhesion strength to general material, requires bonding technology have certain adaptability and satisfaction,
But more and more timber have respectively different requirements to the glue product of bonding at present, hot melt adhesive simple at present has been difficult to meet
The needs in market, such as the high temperature resistant degree, adhesion strength, degree easy for construction of hot melt adhesive, efficiency etc. is not adapted to
The timber of particular/special requirement is smooth to be used；The polyurethane adhesive of low side is with the raw material of simple hydroxyl and containing-NCO group
MDi raw material reacts to form the solidified body of certain commissure intensity to reach the bond effect to ground.This glue overcomes on the whole
The disadvantages of hot melt adhesive is unable to high temperature resistant, sizing temperature is excessively high, but polyurethane that this simple hydroxyl raw material is produced
Poor to the fitting effect of nonpolarity material, hardness is excessive after glue product congealing reaction, and resistance to low temperature is poor, brittle, heat dissipation performance
It is poor, it is not able to satisfy the requirement of the woodwork of high quality.Therefore, developing the smooth glue of adaptable polyurethane wood becomes originally
The key technology difficulty in field.
Summary of the invention
In order to overcome the deficiencies in the prior art described above, the present invention provides a kind of polyurethane wood of strong adaptability is smooth
With glue, which has excellent initial bonding strength, and curing rate is fast, and cured later power is big, and glue sample is uniform, good heat conductivity, resists low
The advantages that temperature, high temperature, the later period is non-yellowing, bubble-free.It overcomes general hot melt adhesive or low side polyurethane initial bonding strength is small, curing time
Long, glue sample is uneven, and heating conduction is bad, and adaptation low temperature, hot environment are poor, and the later period is easy yellowing, heated to be easy to produce bubble
The defects of.
The present invention is achieved through the following technical solutions above-mentioned technical effect:
The present invention provides a kind of smooth glue of polyurethane wood of strong adaptability, and the polyurethane wood is smooth to use glue by following matter
Measure the raw material composition of number: C9 Petropols, aluminium powder, unformed polyalphaolefin, EVA resin, polyadipate hexylene glycol glycol, virtue
Fragrant race's copolyesters, 4,4'- methyl diphenylene diisocyanate, mass ratio is respectively 1~18 part, 30~50 parts, 5~10 parts,
12~15 parts, 10~20 parts, 13~30 parts, 7~10 parts.
Preferably, the polyurethane wood is smooth is made of with glue the raw material of following mass fraction: C9 Petropols, aluminium
Powder, unformed polyalphaolefin, EVA resin, polyadipate hexylene glycol glycol, aromatic copolyester, 4,4'- diphenyl methane two are different
Cyanate, mass ratio are respectively 8~12 parts, 40~45 parts, 6~8 parts, 13~15 parts, 12~18 parts, 18~25 parts, 8~10
Part.
Optimal, the polyurethane wood is smooth to be made of with glue the raw material of following mass fraction: C9 Petropols, aluminium
Powder, unformed polyalphaolefin, EVA resin, polyadipate hexylene glycol glycol, aromatic copolyester, 4,4'- diphenyl methane two are different
Cyanate, mass ratio are respectively 10 parts, 42 parts, 6~8 parts, 14 parts, 16 parts, 21 parts, 9 parts.
The present invention provides a kind of smooth glue of polyurethane wood of strong adaptability, and those skilled in the art can be used, and oneself knows
Method preparation, screw rod extrusion by melting and reaction kettle melt mixing methods usually can be used.
The smooth polyurethane wood of strong adaptability of the present invention with glue is a kind of block containing soft segment, hard section and transition
Copolymer, soft segment are made of oligomer polyester, polyethers, and hard section is made of polyisocyanates or other chain extenders, transition by
APAO resin composition.Their mutual commissures, performance complement collectively form the excellent structure of product.Due to the heating power of three kinds of segments
Incompatibility is learned, they have microcosmic mutually separation, a presence of phase region and microfacies area can be had in their inside, in polyurethane
The groups such as existing ether, urea, urethane can generate hydrogen bond, and wherein APAO has biggish contribution, urea bond and ammonia to the flexibility of product
Ester bond has larger contribution to the hard section of product, and hard section is cross-linked with each other with soft segment and APAO, is complementary, thus forms product uniqueness
Flexibility and wide scope physical property.The excellent performance of the product be firstly because that microcosmic phase region formed as a result, with the time
Passage, then the hydrogen bond action of hard section and soft segment occurs.
The present invention provides a kind of smooth glue of polyurethane wood of strong adaptability, which has excellent initial bonding strength, Gu
Change speed is fast, and cured later power is big, and glue sample is uniform, good heat conductivity, low-temperature resistance, high temperature, and later period non-yellowing, bubble-free etc. is excellent
Point.It overcomes general hot melt adhesive or low side polyurethane initial bonding strength is small, curing time is long, and glue sample is uneven, and heating conduction is bad, fits
Answer low temperature, hot environment poor, the later period is easy yellowing, heated the defects of being easy to produce bubble.
