A method for molding products from unusable tires is disclosed. The composition for molding consists of pulverized tires, one or more resins selected from polypropylene resin, low density polyethylene resin and high density polyethylene resin and one or more chemicals selected from the group of acetone, caustic soda, glass wool, ammonium phosphate, starch and pigments. The composition components are well mixed, melted at 230 DEG C to 350 DEG C and molded by injecting, extruding or pressing. Products formed from the composition can be used to form various kinds of industrial construction materials which have high strength and smooth surface.

Description

Method with manufacturing mold products with unusable tires
The present invention relates to the regeneration of junked tire, particularly have the method for various layered products of different nature with the mixture production of junked tire powder, various resin and chemicals.
In current society, the whole world generally acknowledges that auto industry is output maximum, fastest-rising industry.Automobile-the useful and the most necessary vehicles of the mankind not only makes convenient transportation, and closely related with daily life.Particularly in the society that people need frequently migrate, even can not imagine and do not have automobile can keep their daily life.But along with increasing rapidly of auto output, the environmental pollution that causes because of automobile has brought serious problems to us.
Air pollution that environmental pollution such as the toxic gas that causes except that automobile causes or the discarded in the street automobile, discarded old tire also is one of reason that makes severe environmental pollution.People have carried out many-sided recovery junked tire to prevent the pollution of the environment and to make the energy trial that is utilized effectively.But regrettably, also very few with the product category that old tire is produced, and the tire amount that has reclaimed is compared also seldom with the tire amount of production in enormous quantities; Junked tire is cut into fillet and makes rope or the rubber basket.Except above-mentioned recovery method, a large amount of junked tires are thrown into the ashing of burning in the incinerator.Not only produce toxic gas and cause air pollution but burn tire, and slatterned precious resources, and these resources this recyclablely be processed into raw material and produce various products again.In addition, law forbids burning tire now, so we are faced with the tire new problem of the enormous amount that reclaims industrial production in enormous quantities.If we can become useful resources to junked tire, just can prevent the pollution of the environment and energy savings.For the present invention, be the mixture that might utilize junked tire powder, various resin and chemicals.The present invention reduce to pollute, is saving the valuable energy and finally to the breakthrough really aspect the contribution of national industry development.
In order to find solution to the problems described above, the inventor has dropped into the recovery technology of a large amount of financial resources research old tires, make finally a kind of support again utilize, be suitable for the raw material in a lot of different field of industry, used.
An object of the present invention is to reclaim junked tire and make it to become useful resource.
Another purpose of the present invention is to prevent because of burning the environmental pollution that tire causes.
Further object of the present invention provides the method for producing various layered products, and these layered products can satisfy various requirements, for example have smooth surface, firm structure, appearance attractive in appearance or the like.
According to the present invention, the method of producing various layered products with junked tire may further comprise the steps: with the junked tire powder, one or more resins that are selected from polypropylene, low density polyethylene (LDPE) and high density polyethylene (HDPE) mix mutually with the chemicals that one or more are selected from acetone, caustic soda, mineral wool, ammonium phosphate, starch and pigment; Mixture is melted between 230 ℃ to 350 ℃; By injecting, extruding with drawing method and carry out molding.
In the present invention, the size to the junked tire powder particles does not have special provision.So junked tire can be crushed to the particle of suitable size according to the purposes of required product.Amount to junked tire powder in the mixture is unqualified, but desirable consumption is 15% to 90% of a mixture weight.Be fine grained for junked tire is pulverized, it is more effective using the freezing crushing technology of liquid nitrogen.
That each had been used or discarded resin can replace above-mentioned resin such as acrylic resin, ldpe resin and high-density polyethylene resin, and the desired contents of above-mentioned resin is lower than 50% of composition weight respectively.Nylon, polyester or other synthetic resin can add wherein or replace above-mentioned resin.
According to the purposes of required product, use one or more chemicals in acetone, caustic soda, mineral wool, ammonium phosphate and the pigment.For example, the production smooth surface and firm product such as building board, shop use brick and chest in the street, just must be with acetone, caustic soda, mineral wool, ammonium phosphate, starch and pigment.Produce clean water tank, irrigate water-supply-pipe and sewage pipe, available acetone, mineral wool, ammonium phosphate and starch.Produce flexible sheet material, bucket and washbowl, then used caustic soda, mineral wool, ammonium phosphate and starch.For having elasticity and high-intensity product,, mix with the junked tire powder with acetone, caustic soda, mineral wool, starch and some pigment as the central partition on the expressway.For the breakwater at beach, use acetone.For dykes and dams and the pallet of the product that needs high rigidity and hot strength, use mineral wool, ammonium phosphate, starch and pigment as preventing to come down.For the indoor hardware fitting that needs good hardness such as brick and building frame, must use mineral wool, acetone, ammonium phosphate and pigment.
Limiting that the correct weight of various chemicals is very difficult in the mixture, is desirable but use the starch of ammonium phosphate and 15% (weight) of mineral wool, 5% (weight) of the caustic soda, 30% (weight) of the acetone, 0.5% (weight) that is less than about 0.5% (weight).
Acetone is used as solvent, if its use amount surpasses 5% (weight), then reduces because of the excessive meeting of solvent causes product quality.Caustic soda produces a lot of micro-bubbles and increases the cushioning ability and the elasticity of product in mixture.Caustic soda excessive (more than 0.5%) can cause bubble too much in the product, also can reduce product quality.Mineral wool increases the hear resistance of product, but if excessive meeting reduces product quality, the moulding process of product is encountered difficulties.Ammonium phosphate increases the anti-flammability of product.
By the following examples the present invention is illustrated, wherein, except other had regulation, all percentages all were percentage by weights.
