Embodiment 1

[0043] A layer of polyurethane resin coating with 12.5% ​​solid content (containing 87.5% solvent) is coated on a release paper, wherein the viscosity of the resin coating is controlled at 1300cps / 30°C. The polyurethane resin coating was dried in an oven at 110° C. to form a one-sided layer.

[0044] A polyurethane resin coating with a high solid content is coated on the dry surface layer, wherein the coating is made of 67% by weight polyurethane resin (solid content 93%), 20% phosphorus flame retardant and antimony oxide (Sb 2 o 3 ) (the weight ratio of phosphorus flame retardant and antimony oxide is 2:1), 1% interface agent, 4% hardener, 6% filler and 2% colorant, and its viscosity is controlled at 25000cps / 30℃. The polyurethane resin coating with high solid content was baked and hardened by an oven at 160° C. to form an intermediate layer.

[0045] On the hardened intermediate layer, coat a polyurethane resin coating with a solid content of 35% to form an adhesive layer...

Embodiment 2

[0050] A layer of foamable polyurethane resin coating with a solid content of 12.5% ​​is coated on the release paper, wherein the viscosity of the resin coating is controlled at 1300cps / 30°C. The polyurethane resin coating was dried in an oven at 110° C. to form a one-sided layer.

[0051] A polyurethane resin coating with a high solid content is coated on the dry surface layer, wherein the coating is made of 40% by weight polyurethane resin (solid content 93%), 12% phosphorus flame retardant and antimony oxide (Sb 2 o 3 ) (the weight ratio of phosphorus flame retardant and antimony oxide is 2:1), 0.5% interface agent, 7% hardener, 38.5% filler and 2% colorant, and its viscosity is controlled at 25000cps / 30℃ . The polyurethane resin coating with high solid content was baked and hardened by an oven at 130° C. to form an intermediate layer.

[0052]On the hardened intermediate layer, coat a polyurethane resin coating with a solid content of 35% to form an adhesive layer. The...

Abstract

This invention relates to a burning-resistant environment protection artificial leather including a backing, a followed layer, an interface layer and a surface layer, in which, the character of the leather is that an interface layer formed by a solid PUR resin component with the Cl-free burning-resistant agent is added in it including a burning-resistant agent, a PUR resin with the solid phase higher than 50% and a hardener. A manufacturing method is also provided.

Description

technical field [0001] The invention relates to a method for manufacturing flame-resistant, environmentally-friendly artificial leather and the prepared flame-resistant, environmentally-friendly artificial leather. Background technique [0002] Conventional leather-like artificial leather manufacturing methods, such as figure 1 As shown, it includes two main processes, one is a dry process 100 and the other is a wet process 101 . The dry process 100 includes two main steps 102 and 104. First, a layer of dry polyurethane resin composition is coated on the release paper to form a dry polyurethane resin layer with a thickness of about 0.02 mm to 0.03 mm (step 102), Then coat the dry polyurethane resin layer with an adhesive polyurethane resin composition with a thickness of about 0.04mm˜0.05mm to form an adhesive layer (step 104 ). The wet process 101 includes four main steps 106-114. First, a substrate is impregnated with a polyurethane resin composition for impregnation to ...
