Description
Technical field
The present invention relates to a kind of preparation method of polyurethane rigid foam wood-like material, specifically, the present invention relates to a kind of mixture with polyether glycol, catalyzer, suds-stabilizing agent, whipping agent, fire retardant etc. is white material, be black material with poly methylene poly phenyl poly isocyanate (PAPI), the two mixes, reacts the method that moulding prepares polyurethane rigid foam wood-like material under certain condition by a certain percentage.
Background technology
Natural timber of many uses is requisite materials used in people's productive life.But the several years; lack enough protections owing to the overexploitation of the forest reserves and to the existing forest reserves; caused a large amount of losses of Ecological environment worsening and water and soil, thereby the exploitation and the exploitation of the natural forest resourceies of control have been give stricted orders, the prevention denudation by some countries.So the substitution problem of timber causes people's extensive concern gradually.
The existing raw material that is used for synthetic wood has multiple, generally with inorganic or organic filler and the manufacturing of tackiness agent employing mould pressing process.Mineral filler has lime carbonate, talcum powder etc., organic filler mainly is natural fibers such as straw, stalk and crudefiber crop, the resin that is used for imitated wood material mainly contains polyvinyl chloride, polyester, polystyrene, ABS etc., but the ubiquity goods are big for environment pollution, goods are short work-ing life, problems such as intensity difference.
The polyurethane structural porous plastics is 20th century a kind of middle-high density poromerics of growing up of the mid-1970s, because the rigidity and the physical strength height of this material, density is low, but supporting capacity is strong, can substitute other materials such as the bigger conventional gypsum plate of density, polyester, glass reinforced plastic, be used for synthetic wood.
In recent years, polyurethane rigid foam wood-like material has become a frontier of various countries' researcher research and development.Many traditional Application Areas at natural timber, polyurethane rigid foam wood-like material part has substituted timber, as having obtained using widely at aspects such as wood furniture, door and window, electric appliance casing, tub, engraving finishing device, picture frames, and this kind material can be followed closely, can dig, can saw, and outward appearance, feel, density and natural timber are similar, also have moistureproofly, anti-damage by worms, fire-retardant, the characteristics that are better than timber such as need not to paint.
Polyurethane rigid foam wood-like material is the structural rigid urethane foam of a class middle-high density, and it has fine foam structure, and density is usually above 0.2g/cm
3The polyurethane rigid foam plastic that is used for synthetic wood has fine and close tough and tensile epidermis, make this synthetic materials not only have the outward appearance and the density range of timber, and the bulk strength of goods is higher, and the core of product can be accomplished lower density, thereby can alleviate the weight of product.
The polyurethane imitation wood material is compared tangible advantage with natural timber be can be by die design, molded batch process different shape, moulding process is simple, and product repeats excellent property, production efficiency height, particularly accurately duplicate the carving handicraft article of various complexity, form is true to nature, and large-scale industrial production can be realized by product in the time and labour saving, production technique is simple, once shaped production efficiency height.Strength ratio natural timber height, density is lower than natural timber, resistance to acids and bases and antiseptic property excellence.In addition, this kind material can have very strong flame retardant properties as required, and the oxygen index of goods and smoke density can be regulated within the specific limits, satisfies different service requirementss.Thereby the alternative natural timber of polyurethane rigid foam wood-like material is subjected to user's welcome deeply as all kinds of high-grade goods, so nearly 10 years China's polyurethane rigid foam wood-like materials have obtained developing rapidly in industries such as furniture wood industry, decorative engineering.
Summary of the invention
The invention provides a kind of preparation method of polyurethane rigid foam wood-like material, mixture with polyether glycol, catalyzer, suds-stabilizing agent, whipping agent, fire retardant etc. is white material, be black material with poly methylene poly phenyl poly isocyanate (PAPI), the two mixes, pours into a mould, reacts moulding under certain condition by a certain percentage and prepares polyurethane rigid foam wood-like material.
The present invention realizes by following measure:
The invention discloses a kind of preparation method of polyurethane rigid foam wood-like material, this kind imitated wood material mixes, reacts moulding by white material and black material and makes under certain reaction condition, certain proportion.White material is made up of the blend of polyether glycol, catalyzer, suds-stabilizing agent, whipping agent, fire retardant etc., and black material is poly methylene poly phenyl poly isocyanate.
