Description
Technical field
The invention belongs to the cleaners and polishes production technical field, especially relate to a kind of production technology of utilizing acrylic and polyurethane to make cleaners and polishes.
Background technology
Along with improving constantly of living standard, people also improve the quality requirements of sanitary equipment thereupon.Cleaners and polishes such as toilet, hand basin, urinal, bidet, urinating bucket are that ceramic sintering forms basically at present, ceramic sanitary appliance has the following disadvantages: the first, resist ability, and be afraid of bump, easily impaired, even crackle seepage phenomenon appears, is unfavorable for transportation and installs; The second, appearance is attractive in appearance inadequately, dull coloring; Pottery is difficult to do color, adds pigment toward the mud the inside and just is difficult to, even if added, the different place of firing temperature has aberration, and the color of each batch comes out also to have any different, and also wants glazing in addition, it also is technical barrier that glaze adds color, and very expensive, and scrappage is very high.The 3rd, not energy-conserving and environment-protective of pottery, predation soil property, high-temperature firing, CO2 emission cause that dust pollution, water pollute, noise pollution, and refuse can not decompose utilization, and the energy does not meet the requirement of environmental protection and sustainable development with labour-intensive; The 4th, ceramic processing time consuming effort, production efficiency is low.The 5th, there is the water absorption rate problem, water absorption rate is to judge very important index of ceramic sanitary appliance, just receives dirt because of existing water absorption rate to be easy to soil pick-up, shorten the life-span, and acrylic does not have water absorption rate and do not have radiation.Bathtub, shower house are basic now to adopt acrylic board to make, but back-up coat all adopts unsaturated-resin and fiber to repeat to spread the felt brushing by hand and forms, have the following disadvantages: (1), usefulness unsaturated-resin and fiber reinforced have the volatilization of styrene toxic gas, not environmental protection in the operating process; (2), misoperation, burn cylinder or delamination easily, scrappage is too high, scrappage can't utilize and handle again; (3), durability is not strong, service life is short, and appearance is not attractive in appearance; (4), the energy and labour intensive, do not meet the sustainable development requirement, production efficiency is extremely low, producing a bathtub needs at least three four hours, inapplicable mechanization production requirement and added value are not high.
Along with development of technology, at present existing indivedual producers have produced with resin mixes the cleaners and polishes such as acrylic toilet that stir cast then or form with Paris white or other stone flours, though the deficiency to above-mentioned production technology improves to some extent, but still there are many deficiencies: toxic gas volatilizations such as big weight phenylethylene are arranged in (1), the operating process, stir polishing processing and cause noise pollution, water pollution, dust pollution, atmosphere pollution, do not meet environmental protection requirement; (2), work and energy intensive, can't adapt to the mechanization requirement, do not meet the sustainable development requirement; (3), production efficiency is low, producing a toilet needs 5-6 hour hot setting time at least, produces in batches if desired, can produce once more after needing large quantities of identical moulds to wait for to solidify; (4), durability and aesthetics are not enough.(5), there is the water absorption rate problem, just receives dirt, shorten the life-span because of existing water absorption rate to be easy to soil pick-up.
Summary of the invention
In order to solve the deficiency that prior art exists, the purpose of this invention is to provide a kind of production technology of making attractive and durable environment-friendly high-efficiency cleaners and polishes such as toilet, shower house, bathtub, hand basin, urinal, bidet, urinating bucket with acrylic sheet material and polyurethane.It has improved operating efficiency, has alleviated hand labor intensity, has reduced production cost, energy-conserving and environment-protective, the attractive and durable environmental protection of the product of producing.
To achieve these goals, the production technology of acrylic of the present invention and polyurethane sanitary ware comprises the steps:
(1) parts moulding: the needed parts of sanitary equipment are standby with corresponding parts mould blowing or plastics sucking moulding by the thermoplastic shaping machine with acrylic sheet material;
(2) preheating of parts and location: the parts that moulding is finished carry out preheating, location;
(3) spraying: preheating and the parts of having good positioning are set aside to spray booth respectively, spray to the position that parts need spray with the polyurethane bicomponent material by paint finishing mixing match as required, at spraying moment polyurethane bicomponent material generation chemical reaction, be one with each parts foamed solidification of having good positioning;
(4) finishing assembling: the all-in-one-piece parts that will foam finishing is assembled into finished product according to the sanitary ware part requirement integration;
Acrylic sheet material main chemical described in the step (1) is methyl methacrylate or EMA.
The preheating of the parts described in the step (2) is parts to be placed in the baking oven control preheating by temperature control system, and preheat temperature is between 30 degree～80 degree; The location is parts to be placed on the positioning table locate; The order of preheating and location can be changed mutually.
Polyurethane bicomponent material described in the step (3) is a kind of polyether polyols with reduced unsaturation, mainly form by polyalcohol component and isocyanate component two-component materials, it is between 1: 1～1: 2 or 1: 1～2: 1 that polyol component sprays proportioning with mixing of isocyanate component, and its density is 300Kg/m
3～1500Kg/m
3
Polyurethane coating system described in the step (3) is high pressure or low pressure polyurethane coating foamed system, mainly is made up of spray coating foaming machine, spray gun, feeding system, suction system.
Can add fiber, stone flour or other auxiliary raw material that strengthens in the polyurethane bicomponent material described in the step (3).
The invention has the beneficial effects as follows: there are not toxic gas volatilizations such as styrene in (1), the operating process, the processing and manufacturing of directly foaming, noiselessness pollution, water pollution, dust pollution, atmosphere pollution meet environmental protection requirement.(2), produce an acrylic toilet in the prior art, several people one talent does a product.Adopt production technology of the present invention, the several people can do a hundreds of product in one day, had improved production efficiency greatly, had reduced hand labor intensity.(3), enhance productivity and reduce production costs, producing a toilet in the prior art needs 5-6 hour hot setting time at least, produces in batches if desired, can produce once more after needing large quantities of identical moulds to wait for to solidify; And the present invention has saved the hot setting step, has saved production cost.(4), the product produced of the present invention, attractive and durable energy-conserving and environment-protective.
