Abstract
The present invention relates to a kind of fire retarding polyurethane synthetic leather and preparation method thereof, the raw material components of this fire retarding polyurethane synthetic leather includes nitrogen phosphorus composite flame-retardant agent, solvent borne polyurethane, the dispersion material component of described nitrogen phosphorus composite flame-retardant agent is filled a prescription as follows by weight: phosphorous titanate esters 0.5-2.0 part, solvent 60-110 part, described nitrogen phosphorus composite flame-retardant agent is based on phosphorus, with nitrogen is auxilliary, and phosphorus-nitrogen ratio is 4: 1-2: 1.The existing highly effective flame-retardant of this fire retarding polyurethane synthetic leather can satisfy Europe, the United States' environmental requirement again, is suitable for car, ship and sofa field.
Description
Technical field
The invention belongs to anti-flammability synthetic leather field.
Background technology
Be used for making the macromolecular material of synthetic leather, mainly contain two kinds of materials at present: a kind of is Corvic (abbreviation polyvinyl chloride resin); A kind of is polyurethane resin (being called for short the PU resin).From the flame-retarded technology angle, polyvinyl chloride resin is more fire-retardant, because polyvinyl chloride resin itself just possesses certain anti-flammability, the PU resin then is a kind of combustible material, and it is big that it is implemented the flame-retarded technology difficulty.Publication number for " CN1693577 " thus Chinese patent put down in writing additive flame retardant and reactive flame retardant milled and disperseed or the reaction copolymerization prepares the Synthetic Leather of anti-flammability in the solvent borne polyurethane system, but the selection to anti-flammability there is no explanation, and fire retardant is to influence the key factor that can Synthetic Leather reach flame-retardant standard.Selection of fire retardant is most important for the purpose that environmental protection reaches to reaching the flame-retardant standard requirement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of fire retarding polyurethane synthetic leather, and the existing highly effective flame-retardant of this fire retarding polyurethane synthetic leather can satisfy Europe, the United States' environmental requirement again, is suitable for car, ship and sofa field.
For solving above technical problem, the present invention adopts following technical scheme:
A kind of fire retarding polyurethane synthetic leather, the raw material components of this fire retarding polyurethane synthetic leather includes fire retardant, solvent borne polyurethane, the material component of the dispersion of fire retardant is filled a prescription as follows by weight: phosphorous titanate esters 0.5-2.0 part, solvent 60-110 part, described fire retardant is a nitrogen phosphorus composite flame-retardant agent, fire retardant is based on phosphorus, with nitrogen is auxilliary, and phosphorus-nitrogen ratio is 4: 1-2: 1.
The raw material components of described fire retarding polyurethane synthetic leather also includes filler 5-35 part, colouring agent 2-15 part, and described filler is a cellulose powder, and its granular size is the 200-1250 order.Described colouring agent is the environment-friendly type pigment paste, and its solid shape content is 30%-60%, and solvent is a dimethyl formamide.
A kind of preparation method of described fire retarding polyurethane synthetic leather may further comprise the steps:
(1), the preparation slurry: in solvent, add fire retardant and phosphorous titanate esters, stirred 25-40 minute down, add wet method PU resin then in 5-40 ℃, stir under the vacuum 35-50 minute standby;
(2), preparation wet method fire-retardant bass: adopt wet type synthetic leather production equipment, will be coated by the slurry of (1) preparation and enter coagulating basin behind the synthetic leather base cloth and solidify, washing, oven dry make the fire-retardant bass of wet method;
(3), preparation fire retarding polyurethane synthetic leather: will transfer to dry type synthetic leather production equipment by the fire-retardant bass of the wet method that (2) prepare, and carry out the dry method veneer and make described fire retarding polyurethane synthetic leather.
Because the technique scheme utilization, the present invention compared with prior art has following advantage:
Select nitrogen phosphorus composite flame-retardant agent nontoxic, Halogen, and not only environmental protection but also good flame resistance, flame retardant effect are lasting to add Synthetic Leather that phosphorous titanate esters prepares in its dispersion, and fire resistance reaches Britain BS5852 standard and U.S. FMVSS302 standard.
The specific embodiment
Below the specific embodiment of the present invention is described:
A kind of fire retarding polyurethane synthetic leather, its raw material components comprises 100 parts of environment-friendly type wet method polyurethane resins, 4 parts of nitrogen phosphorus composite flame-retardant agents, 0.5 part of phosphorous titanate esters, 5 parts of colouring agents, 10 parts of cellulose powders, 90 parts of dimethyl formamides, wherein the phosphorus-nitrogen ratio of nitrogen phosphorus composite flame-retardant agent is 3: 1, the granular size of cellulose powder is 1000 orders, colouring agent is the environment-friendly type pigment paste, and its solid shape content is 50%.
The preparation method of described fire retarding polyurethane synthetic leather may further comprise the steps:
(1) preparation of slurry:
Stir 90 parts of dimethyl formamides that add ormal weight in the narrow-necked earthen jar in batching, open and stir, add 0.5 part of 4 parts of nitrogen phosphorus composite flame-retardant agents and phosphorous titanate esters, under room temperature, stirred 30 minutes, and added 100 parts of the environment-friendly type wet method PU resins of ormal weight and 10 parts of cellulose powders, 5 parts of colouring agents again, under vacuum, continue to stir 40 minutes standby, wherein the phosphorus-nitrogen ratio of nitrogen phosphorus composite flame-retardant agent is 3: 1, the granular size of cellulose powder is 1000 orders, and colouring agent is the environment-friendly type pigment paste, and its solid shape content is 50%.
(2) preparation wet method fire-retardant bass: adopt wet type synthetic leather production equipment, will be coated by the slurry of (1) preparation and enter coagulating basin behind the synthetic leather base cloth and solidify, washing, oven dry make the fire-retardant bass of wet method;
(3) preparation fire retarding polyurethane synthetic leather: will transfer to dry type synthetic leather production equipment by the fire-retardant bass of the wet method that (2) prepare, and carry out the dry method veneer and make described fire retarding polyurethane synthetic leather.
After testing, the fire resistance of prepared fire retarding polyurethane synthetic leather reaches Britain BS5852 standard and U.S. FMVSS302 standard.
