Description
Technical field
The present invention relates to a kind of artificial stone, particularly a kind of polyurethane artificial stone for building and preparation method.
Background technology
Stone material because of its by highly ornate decoration effect and long-lived quality widespread use and building decoration and ornaments.Difficulty is big because lithotome is directly exploited, and the dimensions of exploitation is limited, and the rate of becoming a useful person is low, the cost height, and gather lithotome and can destroy natural resources, therefore the application of lithotome is restricted greatly.At present, the artificial stone on the market adopts cement to add water, stone flour, pigment, caking agent, perhaps adds after solidifying agent, stone flour, pigment are mixed into slurry with unsaturated polyester and annotates in die, solidifies to obtain the artificial stone product.The rate height though artificial stone is become a useful person, cost is low, the advantage that dimensions can be produced as required, but, the capillary channel of artificial stone natural rock is stopped up because of using a large amount of caking agents or solidifying agent in emulation stone production process, change the true qualities of lithotome in the artificial stone, artificial stone in the existing market also generally has cutting relatively poor in addition, and moldable property is poor, weight is big, has increased shortcomings such as buildings load-bearing.Chinese patent discloses a kind of " normal temperature consolidated stone material and preparation method thereof ", and the patent No. is 01138342.9, though its normal temperature consolidated stone material has and the identical physical features of lithotome, and manufacture craft is simple, there is energy consumption low, be beneficial to the advantage of environmental protection, but have cutting relatively poor equally, moldable property is poor, the shortcoming that weight is big.
Summary of the invention
The purpose of this invention is to provide a kind of polyurethane artificial stone.The present invention adopts urethane to make foams, can alleviate the weight of polyurethane artificial stone widely, and its thermal and insulating performance is good, and moldable property is strong, and chemical stability is good, helps the advantage of environment protection.
Another object of the present invention provides a kind of preparation method of polyurethane artificial stone, adopts soft mode solid pattern transfer techniques to prepare artificial stone of the present invention, and the specification of its product, outward appearance and color can change arbitrarily, and the low advantage of production cost is arranged.
Technical scheme of the present invention is:
Artificial stone is made up of A component and B component, wherein the composition of A component is polyether glycol, silicone oil, fluoro trichloromethane, water, triethylene diamine, stannous octoate, pentamethyl-diethylenetriamine, and the weight part of each composition is: molecular weight 5000 is 82～88 parts of polyether glycols; Molecular weight 12000 is 2～3.5 parts of polyether glycols; Molecular weight 3000 is 3～5.2 parts of polyether glycols; 0.5～1.2 part of silicone oil; 3.2～5.6 parts of fluoro trichloromethane; 0.15～0.35 part in water; 0.55～1.1 part of triethylene diamine; 0.003～0.01 part of stannous octoate; 0.1～0.55 part of pentamethyl-diethylenetriamine; The B component is a vulcabond; A: B=1: (0.9～1.25)
Stone material optimized technical scheme of the present invention is: the weight part of each composition of A component is: molecular weight 5000 is 85 parts of polyether glycols; Molecular weight 12000 is 2.6 parts of polyether glycols; Molecular weight 3000 is 4 parts of polyether glycols; 1.6 parts of silicone oil; 4.2 parts of fluoro trichloromethane; 0.25 part in water; 0.8 part of triethylene diamine; 0.065 part of stannous octoate; 0.32 part of pentamethyl-diethylenetriamine; The B component is a vulcabond; The proportioning of A, B component is A: B=1: 1.03.
Adopt soft mode solid pattern transfer techniques, get component A, 20～30 ℃ were stirred 30 minutes down; Add B component, stir evenly; In the injection mould, material promptly gets product after solidifying in the mould.
It is that raw material is made foams (PU foam materials) with urethane that the present invention adopts urethane, the lighter in weight of its artificial material, can reduce transportation cost and the load-bearing load that alleviates buildings greatly, thermal conductivity is 0.0174W/mK, its thermal conductivity is minimum in present building and ornament materials, because this artificial material can increase substantially the heat preservation energy-saving performance of buildings, its energy-saving index can reach 50～65% after testing, technical feature reaches the standard of " DB22/T365-2003 " G " engineering construction of rigid urethane foam external wall outer insulation and control of acceptance ", so thermal and insulating performance is good.
Materials chemistry good stability of the present invention can drench with rain and difference variation in anti-Japanese solarization, the weak acid and alkali resistance corrosion.Because material of the present invention need not caking agent and sand-cement slurry, unharmful substance overflows, and is free from environmental pollution, and the building decoration of indoor and outdoor all can use.
The present invention adopts soft mode solid pattern transfer techniques, spraying silicone oil separant on the soft mode face, the artificial stone material after being convenient to solidify separates with soft mode, make the artificial stone of preparation can be because of the not irregular of shape demoulding difficulty.Internal surface at the soft mode die cavity sprays coloured pigment then, be filled in the soft mode die cavity with the PU foam materials and form artificial stone, the pigment of the internal surface of soft mode die cavity infilters artificial stone by bonding and high pressure effect, and the pigment fusion forms colored gorgeous upper layer on the surface of artificial stone.Therefore the present invention has the preparation method of artificial stone simple, the advantage that cost is low.
The present invention adopts soft mode solid pattern transfer techniques, has greatly improved the sticking power of paint on the artificial stone surface, and can pass through the spraying different color on the surface of identical product, forms the combining simulation stone material that there is multicolour on the surface.
The present invention has the texture and the feel of lithotome, and back on probation reflection is good.
