Abstract
The present invention relates to a kind of coir for wood clamp laminate and preparation method thereof, it selects fast growing wood poplar to be veneer, nonwoven acupuncture coir felt, fiberglass gridding cloth, and through poplar rotary cut venner, coir cuts off, break up, dedusting impurity elimination, mats formation, applying glue, precuring, assembly, shaping, obtain coir for wood clamp laminate.This process is simple, do not need particular manufacturing craft, resin added is even, material property and steady quality, stressedly for a long time warpage can not be there is, torsional deformation, foaming, aliquation phenomenon, adopt coir to make sandwich plate for wood, save timber, solve the deficient problem of timber resources, the coconut husk resource of discarding is fully utilized, energy-conserving and environment-protective.
Description
Technical field: the present invention relates to a kind of coir for wood clamp laminate and preparation method thereof.
Background technology: at present, timber resources is deficient, on market, substitute materials for wood is more, there is wheat straw, corn stalk, particieboard, fiberboard, Wood-plastic material, splice plate etc., but their ubiquity bending strengths are poor, tough is little, easily there is warpage in structure, torsional deformation, long-term stressed meeting causes sheet material to be obviously out of shape, affect outward appearance and result of use, and particieboard and fiberboard moisture resistance poor, after absorbing moisture content, the coefficient of expansion is larger, nail-holding ability is poor, screw screws rear easy generation and loosens, coir mechanics of materials strength character is good, especially impact flexibility is large, but annual coconut husk resource is discarded, waste a large amount of coconut husk resources, coconut husk resource is not well utilized.
Summary of the invention: the object of the invention is to overcome above-mentioned shortcoming, there is provided a kind of coir for wood clamp laminate and preparation method thereof, it is poor that it mainly solves substitute materials for wood ubiquity bending strength on market, tough is little, easily there is warpage in structure, torsional deformation and coconut husk resource do not obtain the problems such as well utilization.The object of the present invention is achieved like this, and required material is as follows: fast growing wood poplar 2-4mm thickness veneer, and nonwoven acupuncture coir felt 10-12mm thickness, mesh is the E type fiberglass gridding cloth of 5mm × 5mm.Its preparation method is as follows: a, material prepare: the veneer first fast growing wood poplar being peeled into 2-4mm thickness, coir cuts off, break up, dedusting impurity elimination, mat formation, the shaping nonwoven acupuncture coir felt being prepared into 10-12mm thickness of acupuncture, chooses the E type fiberglass gridding cloth that mesh is 5mm × 5mm; B, applying glue: board using poplar board adopts phenolic resins, one side glue spraying, and glue spraying amount is 10% of veneer weight, nonwoven acupuncture coir felt adopts phenolic resins, two-sided glue spraying, and glue spraying amount is that 10%, E type fiberglass gridding cloth of fibrofelt weight adopts isocyanates, impregnation; C, precuring: material precuring 50min after applying glue; D, assembly: two panels board using poplar board is upper and lower panel, two-layer nonwoven acupuncture coir felt is the sandwich material of panel, and E type fiberglass gridding cloth is reinforcing material in the middle of two-layer nonwoven acupuncture coir felt; E, shaping: first to utilize to cold pressing at normal temperatures and carry out precompressed 10min, pressure is 0.5MPa, then secondary release pressure sintering is adopted, utilizing thickness gage to control thickness is 10-12mm, and hot pressing temperature is 135 DEG C, and hot pressing pressure high pressure is 10Mpa, low pressure is 5MPa, high pressure hot pressing time is 5min, and the low pressure time is 3min, obtains coir for wood clamp laminate.This invented technology method is simple, coir felt is easily standby, because clad can has veneer, coir does not need to adopt special mould for the preparation of wood clamp layer material, size does not specifically limit, do not need the demoulding, product structure good stability, coir is corrosion-resistant, degradation cycle is long, long service life, mechanical strength performance is good, especially impact flexibility is large, can as impact-resistant packing material base plate, decorative panel for building uses, this invented technology adopts two kinds of adhesive, by different materials applying glue respectively, fiberglass gridding cloth adopts isocyanates impregnation, board using poplar board and coir non-woven mat adopt phenolic resins glue spraying, namely ensure that the strength of materials, again save production cost, utilize fiberglass gridding cloth as reinforcing material, make material property balanced, the mechanical property difference of vertical and horizontal is little, the present invention does not need mould, although employ isocyanates, owing to there being panel, therefore the demoulding is not needed, resin added is even, secondary release pressure sintering make material property and quality more stable, stressedly for a long time warpage can not be there is, torsional deformation, bubble, aliquation phenomenon, coir is adopted to make sandwich plate for wood, save timber, solve the deficient problem of timber resources, the coconut husk resource of discarding is fully utilized, energy-conserving and environment-protective.
Specific embodiment:
Getting fast growing wood poplar 2-4mm thickness is veneer, and nonwoven acupuncture coir felt 10-12mm thickness, mesh is the E type fiberglass gridding cloth of 5mm × 5mm.
Its preparation method is as follows:
A, material prepare: the veneer first fast growing wood poplar being peeled into 2-4mm thickness, and coir cuts off, and breaks up, dedusting impurity elimination, mat formation, the shaping nonwoven acupuncture coir felt being prepared into 10-12mm thickness of acupuncture, chooses the E type fiberglass gridding cloth that mesh is 5mm × 5mm;
B, applying glue: board using poplar board adopts phenolic resins, one side glue spraying, and glue spraying amount is 10% of veneer weight, nonwoven acupuncture coir felt adopts phenolic resins, two-sided glue spraying, and glue spraying amount is that 10%, E type fiberglass gridding cloth of fibrofelt weight adopts isocyanates, impregnation;
C, precuring: material precuring 50min after applying glue;
D, assembly: two panels board using poplar board is upper and lower panel, two-layer nonwoven acupuncture coir felt is the sandwich material of panel, and E type fiberglass gridding cloth is reinforcing material in the middle of two-layer nonwoven acupuncture coir felt;
E, shaping: first to utilize to cold pressing at normal temperatures and carry out precompressed 10min, pressure is 0.5MPa, then secondary release pressure sintering is adopted, utilizing thickness gage to control thickness is 10-12mm, and hot pressing temperature is 135 DEG C, and hot pressing pressure high pressure is 10Mpa, low pressure is 5MPa, high pressure hot pressing time is 5min, and the low pressure time is 3min, obtains coir for wood clamp laminate.
