Embodiment 1
[0043] A preparation method for aldehyde-free particleboard, comprising the steps of:
[0044] (1) Preparation of deodorant solution
[0045] ①At room temperature, first add 850g of distilled water into the reaction kettle, then slowly add 125g of sodium hydroxide powder into the reaction kettle, and stir at a constant speed of 500r / min during the addition of sodium hydroxide until completely dissolved to obtain solution Ⅰ.
[0046] ② Add 15g of dichlorovinyl salicylamide and 3g of chitosan to solution I, and continue stirring at a speed of 500r / min until completely dissolved to obtain solution II.
[0047] ③Add 2g of cyclodextrin and 5g of sodium alginate to solution II, and continue stirring at a speed of 500r / min until completely dissolved to obtain a deodorant solution.
[0048] (2) After the shavings are sieved, the potassium permanganate solution with a mass concentration of 0.2% is atomized by spray equipment, and sprayed onto the core shavings through the nozzle; then...
Embodiment 2
[0058] The difference between this embodiment and embodiment 1 is that the application amount of the deodorant solution is set to 2.5kg / m 3 or 10kg / m 3 (i.e. producing 1m 3 The amount of deodorant solution required to add particleboard without aldehyde is 2.5kg or 10kg). Other operations are the same as in Example 1.
[0059] The particle boards obtained by using different oxidants were detected, and compared with the detection results of Example 1, the results are shown in Table 2.
[0060] Table 2.
[0061] Dosage of deodorant 2.5kg / m 3
[0062] It can be seen from Table 2 that as the amount of deodorant increases, the odor level and TVOC of particleboard gradually decrease.
Embodiment 3
[0064] The difference between this embodiment and embodiment 1 is that the applied amount of potassium permanganate solution is set to 0.5kg / m 3 or 2kg / m 3 (i.e. producing 1m 3 The amount of potassium permanganate solution required to add particleboard without aldehyde is 0.5kg or 2kg). Other operations are the same as in Example 1.
[0065] The particle boards obtained by using different oxidants were tested, and compared with the test results of Example 1, the results are shown in Table 3.
[0066] table 3.
[0067] Potassium permanganate solution dosage 0.5kg / m 3
[0068] It can be seen from Table 3 that as the amount of potassium permanganate increases, the odor level and TVOC of the particleboard gradually decrease.
