Embodiment Construction

[0014] The flame retardant particle board of the present invention, its raw material comprises shavings, adhesive and flame retardant material, and described flame retardant material is the mixture of phosphate and modifier, and the addition amount of this flame retardant material is 15-20% of the weight of shavings. %, the amount of adhesive added is 12-15% of the weight of wood shavings. The phosphate is ammonium dihydrogen phosphate and diammonium hydrogen phosphate, and the modifier is 4A molecular sieve. The additive amount of the modifier is 2-4% of the weight of the phosphate. The weight ratio of the formula is based on the absolute dry wood shavings as a reference. Usually, during production, the wood shavings can be produced normally within the range of moisture content of 3-12%. The weight of the dry wood shavings can be calculated according to the moisture content of the wood shavings. The weight of the adhesive is calculated based on the solid content of the adhes...

Abstract

The invention discloses a flame-retarded shaving board with an inflaming retarding property and a manufacturing method thereof. The flame-retarded shaving board comprises wood shavings, adhesive and a flameresistant material, and is characterized in that the flameresistant material is mixed solution of diammonium hydrogen phosphate, ammonium dihydrogen phosphate and a 4A molecular sieve; the addition amount of the flameresistant material is 15-20% of the weight of the wood shavings; the addition amount of the adhesive is 12-15% of the weight of the wood shavings. The flame-retarded shaving board manufactured by the formula and the method is suitable for the fields of furniture, packaging, building, interior and outdoor decoration and the like.

Description

technical field [0001] The invention relates to a flame-retardant particle board with flame-retardant properties and a manufacturing method thereof. Background technique [0002] As a furniture and decoration material, particleboard is increasingly used in homes and workplaces. At present, the main raw materials of ordinary particleboard are wooden materials such as sawdust or wood shavings and adhesives. Since wood materials are flammable, particleboard The safety problem in the use process is also paid more and more attention by people. According to the requirements of the national standard GB20286-2006, decoration and furniture materials, especially decoration and furniture materials in public places, have mandatory flame retardant requirements. The flame retardant performance of the existing ordinary particleboard has not met the requirements, which limits the use of particleboard in furniture and decoration applications. How to manufacture and produce particle boards ...
