Temperature-control PU processing process of wood floors

Abstract

The invention discloses a temperature-control PU processing process of wood floors. The processing process comprises the following steps: (1) arranging tongues and grooves on four sides of solid wood stock or a solid composite substrate with a water content of 9-14 percent and sanding the surfaces; (2) heating the surfaces of the wood floors to 35-45 DEG C by UV painting line equipment, manually coating mixed oil of cedar wood oil and tea tree oil on six sides of the wood floors and naturally drying the wood floors for more than 10 hours; (3) coating the mixed oil of the cedar wood oil and the tea tree oil under the condition that superficial oil is not sticky and naturally drying for more than 16 hours; (4) coating the mixed oil of the cedar wood oil and the tea tree oil under the condition that superficial oil is not sticky and naturally drying the wood floors for more than 24 hours; (5) sprinkling the PU mixed oil on the surfaces in a shower under the condition that superficial oil is not sticky; (6) sprinkling the PU mixed oil on the surfaces under the condition that superficial oil is not sticky; and (7) casing and packaging wood floors under the condition that the superficial oil is not sticky. The invention has the advantages of lessening mechanical paint, lowering environmental pollution, freeing harm to constructors and naturally protecting environment.

Description

technical field [0001] The invention relates to a wood floor treatment process, in particular to a wood floor temperature-controlled PU treatment process. Background technique [0002] There are generally three kinds of existing solid wood floor paint methods: the first is the UV process adopted by most manufacturers, due to the fast drying time, the penetration of the paint is shallow and the adhesion is poor; the second is the natural drying PU process, due to the need for more If the polyester paint is used repeatedly for the first time, the floor will leave a paint smell; the third is to polish the solid wood plain board after paving, and then apply nitro paint or polyurethane paint on the construction site, which will generate a lot of dust when sanding , which is more harmful to the construction personnel, and the paint will cause harm to the construction personnel and pollute the surrounding environment of the site during the process of brushing and drying.
