Abstract
The invention relates to a cast polyurethane elastomer composition for a fashion model. The composition has a two-component system, wherein a component A consists of trifunctional and tetrafunctional polypropylene oxide ether polyol with the molecular weight of 300 to 6,000, 3,3'-dichloro-4,4'-diaminodiphenylmethane (MOCA), a catalyst and other aids; a component B consists of isocyanate which is polymethylene polyphenyl polyisocyanate (PAPI), diphenylmethane diisocyanate-50 (MDI-50), carbodiimide modified MDI or a mixture thereof; and the component B and the component A are mixed at room temperature in a weight ratio of 100:(60-70) and the mixture is subjected to centrifugal casting molding to form a cast polyurethane elastomer with the shore D hardness of 70 to 80D and high mechanical property. The cast polyurethane elastomer composition is mainly used for producing the fashion model and other polyurethane sundries which have requirements on high strength and hardness.
Description
Technical field
The present invention relates to a kind of casting type polyurethane elastomer that is used to produce model's material.
Background technology
Urethane is the high molecular synthetic material of a kind of performance between rubber and plastics, is characterized in that the hardness setting range is wide, and the elasticity of existing rubber has the hardness of plastics again, and has the favorable mechanical performance.Because the variety of urethane raw, polyurethane products penetrate in the daily life fully.It is with PVC or PVC blending glass reinforced plastic that traditional model expects to produce, and this product processes is complicated, and energy consumption is big; Production cycle is long, and product fragility is big, the high temperature flexible type; Be difficult for degraded, these products are owing to the limitation of environmental protection is necessary to substitute with a kind of new product simultaneously.
The present invention adopts the diphenylmethanediisocyanate of the low smell of MDI system, and some polyether glycol and MOCA, catalyzer and other auxiliary agent are formed polymeric components in addition.Two component mixed room temperatures obtain a kind of polyurethane elastomer material of fast demoulding, compare with PVC product commonly used that environmental-protecting performance is more excellent, toughness is better.
Summary of the invention
Technical problem to be solved by this invention provides a kind of casting type ammonia ester elastomer composition of fast demoulding; Itself environmental pollution is little; Production process is simply efficient, and has suitable viscosity and flowing time, and resulting product not only has rigid structural but also have snappiness; The indeformable characteristics of high temperature can be used to produce model and other urethane sundries.
A kind of casting type polyurethane elastomer of producing model's material of the present invention is characterized in that being made up of two kinds of components:
A component: by weight percentage; With functionality is 3 or 4; Polypropyleneoxide ethoxylated polyhydric alcohol 30%～50%, the functionality of number-average molecular weight in 300～500 scopes is 3, polypropyleneoxide ethoxylated polyhydric alcohol 34%～64.5%, aromatic diamine solidifying agent 5%～15%, catalyzer 0.01%～0.05% and the gas-phase silica 0.2～1% of number-average molecular weight in 3000～6000 scopes, 100～110 ℃ mix outgas to moisture content less than 0.05%; Wherein catalyzer is selected from one or more of dibutyl tin laurate, organo-bismuth, organic zinc; The aromatic diamine solidifying agent be selected from 3,3 '-two chloro-4,4 '-diaminodiphenyl-methane;
The B component: isocyanic ester component, used isocyanic ester are selected from MDI or many phenyl polymethine POLYMETHYLENE POLYPHENYLISOCYANATE of diphenylmethanediisocyanate, the modification of charing diimine;
A mixes with 100: 60～70 part by weight with the B component, and mixing temperature is 25 ℃～35 ℃, then according to the centrifugation casting, and 30～40 ℃ of sulfurations demoulding in 10 minutes, obtaining hardness is the polyurethane elastomer goods of shoreD (Shao Shi D) 75 ± 5.
A component of the present invention and the independent packaging of B component, when carrying out production of articles, A mixes with the B component, casting, sulfuration, the demoulding obtain goods.
Used isocyanic ester preferred many phenyl polymethine POLYMETHYLENE POLYPHENYLISOCYANATE such as PM200, M20S, 44V20 etc.
The present invention adopts many phenyl polymethine POLYMETHYLENE POLYPHENYLISOCYANATE (PAPI), because many phenyl polymethine POLYMETHYLENE POLYPHENYLISOCYANATE (PAPI) saturated vapor pressure is high, not volatile; Harm to human body and surrounding environment is very little; And do not need pre-polymerization, practiced thrift the energy, selecting molecular weight for use is that 3000～6000 the polyether glycol and the polyether glycol of small molecular weight are used; The high-temperature behavior that can increase product can improve toughness again, selects for use arylamine class chainextender to be used to improve the mechanical property of goods.Adopt two component systems simultaneously, goods processing can be carried out under lower temperature, reduced energy consumption and shortened demould time, improved production efficiency.
The present invention is mainly used in the production of model's material, and other needs the preparation of the urethane sundries of high strength and high hardness.
