Description
Technical field
The present invention relates to a kind of method of making glued board.
Background technology
Decorative panel is commonly called as panel, is that the accurate slicing of solid wood plate is become thickness is micro veneer skin more than the 0.1mm, is base material with clamping plate, manufactures the dalle with single or double decoration function that forms through adhesion process.
Formaldehyde has strong adhesion, also have the hardness of strengthening sheet material and insect protected, corrosion-resistant function, the binder of therefore existing sheet material mostly is to be the resinae binder of main component with formaldehyde, under the acting in conjunction of ultraviolet ray, temperature, sunlight, these binders decompose in a large number, free formaldehyde is also just in indoor migration everywhere, the environmental radiation towards periphery that the residual formaldehyde that has neither part nor lot in chemical reaction can be gradually in the sheet material, and this is the main body that forms formaldehyde in indoor air.
Formaldehyde is irritative gas colourless, that have overpowering odor, the aqueous solution common name formalin of its 35%-40%.Formaldehyde is the magma poisonous substance, can and combined with protein, suck high-concentration formaldehyde after, the serious stimulation of respiratory tract and oedema, eye shouting pain, headache can appear, also bronchial astehma can take place.Skin directly contacts formaldehyde, can cause dermatitis, color spot, necrosis.Often suck a small amount of formaldehyde, can cause slow poisoning, mucous hyperemia, skin irritatin disease, allergic dermatitis, nail angling and fragility, nail matrix finger tip pain etc. occur.Constitutional symptom have headache, weak, that stomach is received is poor, palpitaition, have a sleepless night, lose weight and vegetative nervous disorder etc.
Because formaldehyde is extremely harmful to health, in recent years, the researcher all was devoted to seek the preparation method of effective formaldehyde-free decorative board.
For example, Granted publication number discloses a kind of formaldehydeless fire-proof and water-proof decorative panel for the Chinese invention patent of CN1128186C, this decorative panel is primary raw material with the plant fiber powder,, is prepared from according to certain technology as adhesive with the polyvinyl chloride resin powder that do not contain formaldehyde.Because this decorative panel is to be primary raw material with the plant fiber powder rather than to be raw material with the plank, so this patent does not solve the ubiquitous formaldehyde pollution problem of traditional decorative panel (being main component with the solid wood plate).
And for example, Granted publication number discloses a kind of environment protection type composite decorative plate for the Chinese invention patent of CN1164420C, this composite decorating board adopts nontoxic white glues as adhesive, its defective is that this composite decorating board still contains a certain amount of formaldehyde (content of formaldehyde reaches 0.81mg/L), in addition, also there are problems such as preparation cost height, complicated process of preparation in this decorative panel, has to be overcome.Also have numerous these type of researchs, do not exemplify one by one at this.
On the basis of above-mentioned research, CN101554741A discloses a kind of preparation method of formaldehyde-free decorative board, and this method is then colded pressing after the hot pressing by spread plastic sheeting uniformly between every two adjacent plates of solid wood, obtains decorative panel.Preferred embodiment, cold pressing after the first hot pressing, the temperature of hot pressing is 120-140 ℃, and the time of hot pressing is 5-45min; The temperature of colding pressing is 30-40 ℃, colds pressing and the pressure of hot pressing is the 100-600 ton, and the time of colding pressing is 5-45min; The decorative panel that finally obtains soaks in 65-75 ℃ water and did not ftracture in 30 hours, and dries and also do not see cracking in 3 hours.Though this method has effectively been improved the resistance to water and the dry strength of formaldehyde-free decorative board, yet further raising along with current social life quality, people also require more and more higher to every performance of decorative panel, therefore, the preparation method that continues to look for the decorative panel of the better formaldehydeless releases of multinomial performance such as better resistance to water and dry strength also will become more and more severeer problem.
Summary of the invention
The purpose of this invention is to provide a kind of resistance to water, dry strength and fastness and better make the method for glued board.
The invention provides a kind of method of making glued board, described glued board is overlayed by plural veneer and forms, and this method comprises: spread plastic foil between two adjacent veneers, cold pressing after the first hot pressing; Wherein, hot pressing and blanking time of colding pressing are in the 20min.
Method of the present invention has following advantage: (1) and blanking time, within the scope of the invention method was not compared, can be (for example in other condition, plastic foil consumption, hot pressing and the temperature and time of colding pressing) under the identical situation, improve resistance to water, dry strength and the fastness of the glued board that obtains significantly; (2): under the situation of needs acquisition same effect (as essentially identical resistance to water, dry strength and fastness), with blanking time not within the scope of the invention method compare, its requirement lower (for example, the minimizing of plastic foil consumption, hot pressing and time of colding pressing shorten) to the parameter in the manufacturing process; (3) method of the present invention is simple, and equipment is not had specific (special) requirements, is fit to very much the suitability for industrialized production of large-scale glued board.
