Furthermore, the use of "preferred," "preferably," "more preferred," etc., when describing embodiments of the present application, is meant to refer to embodiments of the invention that may provide certain benefits, under certain circumstances. However, other embodiments may be preferred, under the same or other circumstances. In addition, the recitation of one or more preferred embodiments does not imply that other embodiments are not useful, nor is it intended to exclude other embodiments from the scope of the invention. In addition, the starting materials for the present invention are commercially available unless otherwise specified.
In order to solve the above problems, a first aspect of the present invention provides a polyurethane material for furniture foam. The raw materials comprise the following components in parts by weight: 40-68 parts of butter PPG, 20-26 parts of isocyanate, 4-9 parts of silicone oil, 2-7 parts of alcohol amine compounds, 0.5-3 parts of organic tin catalyst, 1-6 parts of solvent and 2-5 parts of water.
In some preferred embodiments, the main raw material of the polyurethane material for furniture foamed cotton is butter PPG.
Applicants have found that by selecting butter PPG to react with isocyanate to form a stable network, the tensile strength of the resulting polyurethane material is increased. The active group provided by the butter PPG can be stably crosslinked with-NCO under the condition, the intermolecular force of the obtained polyurethane with the crosslinked body structure is strong, and the tensile strength of the polyurethane material is improved. Further research shows that when the weight part of the butter PPG is 40-68 parts, the high-temperature aging resistance of the polyurethane material is obviously improved. It is guessed that when the weight part of the butter PPG is 40-68 parts, the fluidity of the polyether, isocyanate and other substances is optimal, the polymer molecular chains are mutually crossed, permeated, tangled and crosslinked, the net structure is compact and firm, the high temperature aging resistance of the polyurethane material is improved, and the tensile strength can still be kept at a higher level even if the product is placed for a long time at a high temperature. However, the resilience of the material is limited by the dense crosslinking of the polyurethane material, so that the collapse resistance of the polyurethane material is slightly reduced.
In some preferred embodiments, the silicone oil includes at least one of a hydroxyl silicone oil, an amino silicone oil, an epoxy silicone oil, and a polyether silicone oil.
More preferably, the silicone oil is amino silicone oil, and the kinematic viscosity of the amino silicone oil is 50-500mm2At 25 ℃ for a period of time. Kinematic viscosity of 50-500mm2The aminosilicone/s (25 ℃ C.) is commercially available, for example from Jinan Hongyun chemical Co., Ltd.
The silicone oil is a high molecular compound with stable chemical properties, has excellent electrical insulation, weather resistance and physiological inertia, can be used as a base material in large amount in industry, and can be used as an auxiliary agent to improve the process performance of other materials. The amino silicone oil is a linear polymer which takes repeated siloxane bonds as a main chain and methyl groups as side groups and is terminated by amino groups, and the reactivity of the amino groups ensures that the amino silicone oil has better compatibility than the silicone oil. The invention discovers that the defect of rough foam holes of a polyurethane material is obviously improved by adding amino silicone oil into the raw materials of the polyurethane, supposes that the amino silicone oil has strong stabilizing effect on the process, inhibits the gas in the reaction process from being rapidly released to cause uneven polyurethane holes and crisp foam pits, and the amino silicone oil reacts with a certain amount of PPG and isocyanate to generate uniform and fine polyurethane holes, thereby avoiding the phenomena of foam collapse and cavities. The invention surprisingly found that the kinematic viscosity of the amino silicone oil is 50-500mm2At 25 ℃, the cell structure of the polyurethane material is improved, and the moisture resistance of the polyurethane material is also improved. Guessing that the kinematic viscosity is 50-500mm2The amino silicone oil/s (25 ℃) has good compatibility with the polyurethane chain segment, the Si-O bond with small surface tension improves the hydrophobicity of the material, and inhibits the influence of water molecules entering the polyurethane structureThe chemical property of the polyurethane material is that the polyurethane material can still keep better mechanical property in an environment with extremely high humidity.
In some preferred embodiments, the alcohol amine compound comprises a tertiary amino group-containing alcohol amine.
Further preferably, the tertiary amino group-containing alcohol amine is N-butyldiethanolamine or N-benzylethanolamine. The CAS number for N-butyldiethanolamine is 102-79-4, and the CAS number for N-benzylethanolamine is 104-63-2.
Still more preferably, the weight ratio of the N-butyldiethanolamine to the N-benzylethanolamine is (0.5-2): 1.
the alcohol amine compound plays a role in extending chain in the preparation process of polyurethane. The present inventors have found that the collapse resistance of a polyurethane material can be improved when the alcohol amine compound comprises a tertiary amino group-containing alcohol amine. The conjecture reason is that the co-action of the alcohol amine of the tertiary amino group and the amino silicone oil and other substances inhibits the micro-phase separation of hard segments and soft segments in polyurethane molecular chains, improves the stress change resistance of the polyurethane material, and improves the anti-indentation and rebound capabilities of the polyurethane material. Further research shows that when the alcohol amine of the tertiary amino is N-butyl diethanolamine and N-benzyl ethanolamine, the rebound rate of the prepared polyurethane material can reach more than 56%.
In some preferred embodiments, the organotin catalyst is dibutyltin bis (dodecylthio) and/or stannous octoate.
The preparation of polyurethanes generally requires the participation of a catalyst. The invention discovers that when the catalyst is organic tin catalyst, the forming time of polyurethane is obviously shortened. The invention unexpectedly discovers that when the organic tin catalyst is selected from dibutyltin dilauryl sulfide and stannous octoate, the organic tin catalyst can act synergistically with substances such as an alcohol amine compound, butter PPG and the like, so that the uniformity of the cells of the polyurethane material is further improved. The reason is probably that the reaction process of the grease PPG with isocyanate and an alcohol amine compound is not too fast due to the dibutyltin dilauryl sulfide and the stannous octoate, the controllability of the foaming and forming reaction degree in the preparation process is enhanced, and the phenomena of foam merging and foam collapse caused by insufficient stability of the foam cells are avoided, so that the uniformity of the foam cells of the polyurethane material is improved.
More preferably, the weight ratio of dibutyltin dilauryl sulfide to stannous octoate is 1: (3-6). The CAS number of dibutyltin bis (dodecyl sulfur) is 1185-81-5, and the CAS number of stannous octoate is 301-10-0.
In some preferred embodiments, the weight ratio of the butter PPG and the amino silicone oil is (5-12): 1.
the invention unexpectedly discovers that the PPG and the kinematic viscosity of the butter are controlled to be 50-500mm2The weight ratio of amino silicone oil/s (25 ℃) is (5-12): 1, the elongation at break of the prepared polyurethane material is improved, and the tensile strength can reach more than 55kPa after dry heat aging and damp heat aging. The guess is that the weight ratio is (5-12): 1, unstable entanglement of polymer chain segments is inhibited, the reaction process is orderly and stable, the firmness and the dispersibility of the obtained polyurethane space network structure are optimal, and the capability of the polyurethane material for bearing dry heat aging and wet heat aging is enhanced.
In some preferred embodiments, the isocyanate comprises at least one of TDI, MDI, HDI, HTDI.
Still more preferably, the isocyanate is MDI.
In some preferred embodiments, the solvent is dichloromethane.
The preparation method comprises the following steps:
adding butter PPG into a reaction kettle, performing vacuum dehydration for 0.5-1h, adding isocyanate, setting the temperature to be 80-85 ℃, and stirring at the speed of 40-80r/min for 2-4 h; adding silicone oil, alcohol amine compound, organic tin catalyst, solvent and water, stirring at the speed of 600 plus 1800r/min for 4-8h, curing and foaming to obtain the finished product.
