Abstract
The utility model relates to a plywood, in particular to an environment-friendly and high-quality plywood taking biobased resin as adhesive. The plywood comprises a substrate which is provided with a biobased resin adhesive layer, and the outside of the biobased resin adhesive layer is provided with a veneer. The plywood is tight in connection among the boards, improves structural strength and is not easy to deform.
Description
Technical field
The utility model relates to a kind of glued board, and especially a kind of environment-friendly type high-quality is the glued board of bonding agent with the bio-based resin.
Background technology
Artificial composite plank is particieboard or the density board that raw material is made with timber at present, its adhesive that uses when producing is the urea-formaldehyde resin adhesive that contains formaldehyde, therefore exists free formaldehyde to discharge the defective of polluting indoor environment when making furniture and interior decoration.Simultaneously with particieboard and density board as load-bearing main body, in making furniture and interior decoration process, have the defective of MOR and nail-holding ability difference.
The utility model content
It is the glued board of bonding agent with the bio-based resin that the purpose of this utility model provides a kind of, in conjunction with closely, has improved structural strength and not yielding between its plate.
For solving the problems of the technologies described above, the utility model comprises: substrate, substrate are provided with the bio-based resin adhesive linkage, and the outside of bio-based resin adhesive linkage is provided with veneer.
Described veneer is more than 2 layers or 2 layers.
It is compound that the utility model adopts multilayer veneer and substrate to pass through the bio-based resin adhesive linkage, its plate structure is firm, improved structural strength, make glued board integral body not yielding, its bonding strength is between the 1.25-1.5, be higher than 1 times of GB 2 class sheet material bonding strength indexs, and in boiling water, boil 72 hours glued boards continuously and do not come unglued.Owing to adopted its free formaldehyde release of adhesive linkage of bio-based resin small, reduced room air pollution simultaneously.
Description of drawings
Fig. 1 is the structural representation of first kind of embodiment of the present utility model.
The specific embodiment
First kind of embodiment of the present utility model as shown in Figure 1 comprises: 1 laminar substrate 1, and the both sides of substrate are provided with bio-based resin adhesive linkage 2, and it is the center line symmetry with the substrate that the outside of bio-based resin adhesive linkage respectively is provided with 3,2 layers of veneer of 1 layer of veneer.The utility model is 3 veneer structures.The bio-based resin adhesive linkage adopts the bio-based resin bonding agent, the making step of bio-based resin bonding agent is as follows: 1. with soybean, wheat bran, starch, rosin milk and water according to 20: 4: 14: after ratio was mixed in 2: 60, heating is in 40 ℃-70 ℃ temperature range, by trypsase and the acting in conjunction of carboxylic ester hydrolase after 24 hours, the adding lactic dehydrogenase is placed on the environment of constant temperature and humidity (temperature is 20 ℃, and relative humidity is 50%-60%) and cultivated 3-7 days down; 2. in 20 minutes, cultured mixing material is heated to 80 ℃-105 ℃, adds oxidizing ferment and stirred 20-30 minute, add an amount of ammoniacal liquor again and regulate pH value between 6.5-7.5, stir and cool off after 2-3 hour.
Second kind of embodiment of the present utility model comprises: 1 laminar substrate, the both sides of substrate are provided with the bio-based resin adhesive linkage, the outside of bio-based resin adhesive linkage respectively is provided with 2 layers of veneer, respectively there are 2 layers of veneer the substrate both sides, the veneer of substrate both sides is the center line symmetry with the substrate, also is provided with the bio-based resin adhesive linkage between the veneer.The utility model is 5 veneer structures.The bio-based resin adhesive linkage adopts the bio-based resin bonding agent, the making step of bio-based resin bonding agent is as follows: 1. with soybean, wheat bran, starch, rosin milk and water according to 20: 4: 14: after ratio was mixed in 2: 60, heating is in 40 ℃-70 ℃ temperature range, by trypsase and the acting in conjunction of carboxylic ester hydrolase after 24 hours, the adding lactic dehydrogenase is placed on the environment of constant temperature and humidity (temperature is 20 ℃, and relative humidity is 50%-60%) and cultivated 3-7 days down; 2. in 20 minutes, cultured mixing material is heated to 80 ℃-105 ℃, adds oxidizing ferment and stirred 20-30 minute, add an amount of ammoniacal liquor again and regulate pH value between 6.5-7.5, stir and cool off after 2-3 hour.
The third embodiment of the present utility model comprises: 1 laminar substrate, the both sides of substrate are provided with the adhesive linkage of bio-based resin, the outside of the adhesive linkage of bio-based resin respectively is provided with 5 layers of veneer, the substrate both sides veneer that respectively is of five storeys, the veneer of substrate both sides is the center line symmetry with the substrate, also is provided with the adhesive linkage of bio-based resin between the veneer.The utility model is 11 veneer structures.The bio-based resin adhesive linkage adopts the bio-based resin bonding agent, the making step of bio-based resin bonding agent is as follows: 1. with soybean, wheat bran, starch, rosin milk and water according to 20: 4: 14: after ratio was mixed in 2: 60, heating is in 40 ℃-70 ℃ temperature range, by trypsase and the acting in conjunction of carboxylic ester hydrolase after 24 hours, the adding lactic dehydrogenase is placed on the environment of constant temperature and humidity (temperature is 20 ℃, and relative humidity is 50%-60%) and cultivated 3-7 days down; 2. in 20 minutes, cultured mixing material is heated to 80 ℃-105 ℃, adds oxidizing ferment and stirred 20-30 minute, add an amount of ammoniacal liquor again and regulate pH value between 6.5-7.5, stir and cool off after 2-3 hour.
As improvement of the present utility model, veneer can be the numbers of plies such as 6 layers, 8 layers, 12 layers.
