One-time forming high-strength decorative slab and manufacturing process thereof

Abstract

The invention discloses a one-time forming high-strength decorative slab and a manufacturing process thereof. The slab comprises the following compositions in portion by weight: 100 portions of 40-to-120-mesh wood powder, 8 to 25 portions of melamine, 0.5 to 2.0 portions of titanium pigment, 0.1 to 1.2 portions of ultramarine blue powder, 0 to 12 portions of active carbon, 0 to 62 portions of fire retardant, 0 to 13.5 portions of aromatizer and 0 to 12 portions of antistatic agent. The manufacturing process comprises the following steps: (1) weighing and respectively storing the compositions according to the weight portions in the formula; (2) setting the temperature of a stirrer between 80 and 110 DEG C, and drying wood powder in the stirrer for 30 to 120 minutes; (3) then, adding the melamine, the titanium pigment, the ultramarine blue powder and auxiliary materials including the fire retardant and / or the aromatizer and / or the antistatic agent to stir again for 15 to 30 minutes, and finally adding active carbon to stir continuously for 10 minutes; (4) obtaining a mixture after heat preservation at a temperature of between 20 and 80 DEG C; (5) maintaining the temperature of the mixture, paving the mixture in a die cavity and covering a decorative film before and after paving the mixture; (6) carrying out sulfuration for 15 to 35 minutes by a flat sulfuration machine at a temperature of between 160 and 170 DEG C under a clamping pressure ranging from 1.4 to 2.6MPa; and (7) transferring the mixture to a cooling machine to cool down the mixture to less than 40 DEG C. The one-time forming high-strength decorative slab has the characteristics of high strength, high toughness, high temperature resistance, aging resistance, waterproofness, environmental protection, no deformation, and the like.

Description

technical field [0001] The invention relates to a building material decorative plate, in particular to a one-time forming high-strength decorative plate and a manufacturing process thereof. Background technique [0002] Traditional solid wood panels can be used directly after drying and surface processing. However, due to the large waste of material processing and the impact of national environmental protection policies, solid wood resources are becoming less and less expensive, and solid wood panels are easy to use. Cracking and deformation affected by ambient temperature. For this reason, a kind of density board is gradually introduced to the market to replace solid wood boards. The density board is usually made of wood slag or plant fiber and mixed with adhesives and resins. The quality varies. Although density boards can replace solid wood boards to save solid wood resources for the country, However, MDF has many defects, such as not being water-resistant, not fire-resi...

[0002] Traditional solid wood panels can be used directly after drying and surface processing. However, due to the large waste of material processing and the impact of national environmental protection policies, solid wood resources are becoming less and less expensive, and solid wood panels are easy to use. Cracking and deformation affected by ambient temperature

For this reason, a kind of density board is gradually introduced to the market to replace solid wood boards. The density board is usually made of wood slag or plant fiber and mixed with adhesives and resins. The quality varies. Although density boards can replace solid wood boards to save solid wood resources for the country, However, MDF has many defects, such as not water-resistant, not fireproof, easy to deform, and releases a lot of harmful substances such as formaldehyde and benzene, which is easy to cause secondary pollution, and cannot meet the requirements of high-end desktop boards in the international and domestic markets.
