Abstract
The invention discloses a method for synthesizing a thermoplastic rigid polyurethane foaming plastic. The method is characterized by comprising the following steps of: blending 30 to 70 weight parts of polyester polyol, 30 to 70 weight parts of polyether polyol, 0.01 to 4 weight parts of foaming agent and 0.01 to 5 parts of surfactant together, uniformly stirring the blended materials to obtain a component A; taking isocyanate as a component B, wherein the equivalent ratio of isocyano in the component B to polyalcohol hydroxyl in the component A is 0.85 to 1.1: 1; and stirring and mixing the component A and the component B at normal temperature and pressure and performing a reaction to obtain the thermoplastic rigid polyurethane foaming plastic after foaming. The method can reduce the production cost of the thermoplastic rigid polyurethane product and meet the increasing demands for products of the market.
Description
Technical field
The present invention relates to the synthetic method of foamed thermoplastic hard polyurethane plastic.
Background technology
Rigid urethane foam is heat cured, but by changing the molecular structure of urethane, can give polyurethane foam certain thermal plastic property, promptly under certain temperature and pressure condition, changes the foamy shape.
Along with advancing by leaps and bounds of automotive industry, the reduction of car price and import tariff, the sales volume of car is advanced by leaps and bounds.Meanwhile, also caused people's attention as the interior material of automobile integral part.
In recent years, the forming technique of automobile top interior trim has had certain development, and early stage automobile top interior trim is progressively replaced by the moulding top owing to can not adapt to the needs of extensive assembling.The development on moulding top is a much progress of top interior trim, not only improved efficiency of assembling, and given the design greater flexibility, has satisfied people's to interior performance and has comprised improving constantly of requirements such as intensity, dimensional stabilizing, heat insulation, sound-absorbing.At present, it is the thermoplastic hard polyurethane roof of base material that the moulding topping material has developed into urethane, and the thermoplastic hard polyurethane roof has experienced the process from thermodyn process to cold modulus method again.
At present, the U.S. adopts thermodyn process thermoplastic urethane foam moulding top interior trim mostly, and cold modulus method thermoplastic polyurethane moulding top is widely adopted in Europe.
In order to adapt to the requirement of car production domesticization, China has successively introduced production line in thermodyn process top interior trim production line and the cold modulus method top, for medium-to-high grade car supporting, the thermodyn process of supporting exploitation and cold modulus method foamed thermoplastic hard polyurethane plastic, its performance index have all reached the level of external like product.Thermodyn process urethane roof has been widely used in cars such as Sang Tanna, Audi, Citroen zx, and cold modulus method urethane roof is also produced in batches.
But the thermoplastic polyurethane product cost of existing market is high, and market value is about 2.3 ten thousand yuan/ton.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, a kind of synthetic method of foamed thermoplastic hard polyurethane plastic is provided, to reduce the thermoplastic polyurethane production cost of products, complying with the demand that market increases day by day for this product.
