Embodiment 1

[0038] A method of preparing flame-retardant decorative base paper using flame-retardant plant fibers in this embodiment comprises the following steps:

[0039] (1) Preparation of flame retardant plant fiber

[0040] (11) Mix coniferous wood pulp and hardwood pulp, add them to the hydraulic pulper, control the pulping concentration to 3.0%, pulping time is 20min, and then discharge the material, and then use the softwood pulp and hardwood pulp with a disk 2 trains and 2 sets of mills are mixed in series and parallel to refine pulp to obtain a beating degree of 37°SR and a plant fiber pulp with a concentration of 5wt%, wherein: the mass ratio of softwood pulp and hardwood pulp in the plant fiber pulp is 1: 0.8.

[0041](12) Add the obtained plant fiber pulp and ammonium persulfate into the reactor, heat and stir at a temperature of 85° C. for 1 hour, then add melamine polyphosphate to the reactor, continue stirring and reacting at a constant temperature of 85° C. for 14 hours,...

Embodiment 2

[0050] A method of preparing flame-retardant decorative base paper using flame-retardant plant fibers in this embodiment comprises the following steps:

[0051] (1) Preparation of flame retardant plant fiber

[0052] (11) Mix coniferous wood pulp, broad-leaved wood pulp, and broken paper pulp, and add them to the hydropulper, control the pulping concentration to 2.5%, and the pulping time is 15 minutes, then discharge, and then use soft-leaved wood pulp and hardwood pulp 2 rows and 2 sets of disk refiners for pulp are mixed and refined in series and parallel to obtain plant fiber pulp with a beating degree of 35°SR and a concentration of 4wt%, wherein: softwood pulp, hardwood pulp and broken pulp in the plant fiber pulp The mass ratio of the broken pulp is 1:0.5:0.5, and the concentration of the broke pulp is 3.0wt%.

[0053] (12) Add the obtained plant fiber pulp and sodium persulfate into the reactor, heat and stir at a temperature of 90° C. for 0.5 h, then add melamine pol...

Embodiment 3

[0062] A method of preparing flame-retardant decorative base paper using flame-retardant plant fibers in this embodiment comprises the following steps:

[0063] (1) Preparation of flame retardant plant fiber

[0064] (11) Mix coniferous wood pulp and hardwood pulp, add them to the hydraulic pulper, control the pulping concentration to 3.5%, pulping time is 30min, and then discharge, and then use softwood pulp and hardwood pulp with a disk 2 trains and 2 sets of mills are mixed in series and parallel to refine pulp to obtain plant fiber pulp with a beating degree of 40°SR and a concentration of 5wt%, wherein: the mass ratio of softwood pulp and hardwood pulp in the plant fiber pulp is 1: 0.5.

[0065] (12) Add the obtained plant fiber pulp and potassium persulfate into the reactor, heat and stir at a temperature of 86° C. for 1.5 h, then add melamine polyphosphate to the reactor, and continue to stir and react at a constant temperature of 86° C. for 15 h, Finally, the fiber i...

Abstract

The invention relates to antiflaming decoration body paper prepared from antiflaming plant fibers, and a preparation method thereof, and relates to the field of antiflaming materials. The ration of the antiflaming decoration body paper is 45-50g / m<2>, and a limit oxygen index is greater than or equal to 28.5%. The antiflaming decoration body paper disclosed by the invention is prepared in a way that antiflaming plant fibers and paper making accessory ingredients are mixed, copied, squeezed, dried, coated and dried again. The antiflaming plant fibers are prepared in a way that plant fiber slurry is taken as a reaction raw material, melamine polyphosphate is taken as reaction type fire retardant, persulfate is taken as initiator, antiflaming grafting modified reaction is carried out under astirring condition at a temperature of 80-90DEG C and then pulp washing is carried out. The decoration body paper prepared with the preparation method has the advantages of good antiflaming performance, excellent physical performance, and the physical strength of the decoration body paper is not affected while fire resistance is guaranteed. In addition, the antiflaming grafting modified waste liquid is used for preparing antiflamming coating, environment pollution can be lightened, production cost is lowered, and the antiflaming decoration body paper has a wide market prospect.

Description

technical field [0001] The invention relates to the field of flame retardant materials, more specifically, the invention relates to a flame retardant decorative base paper prepared from flame retardant plant fibers and a preparation method thereof. Background technique [0002] The lack of global forest resources has led to the mass production of veneer panels. Decorative paper as a surface decoration material for veneer panels has become a widely used decorative material in the furniture industry and building decoration industry. It is widely used in floors, office furniture, wardrobes, fireproof boards, etc. decorate. With the development of society and the improvement of people's living standards, ordinary decorative base paper can no longer meet the requirements of decorative panel materials. For example, from the perspective of fire safety, decorative base paper used indoors generally needs to be treated with flame retardant, so as to reduce its fire hazard and delay T...
