Method of preparing environment friendly foam cotton

Abstract

The invention relates to a manufacturing method of environmental protective foam, in particular relates to a foam manufacturing method, which has an environment protecting effect and can reclaim the waste material of the foam, the manufacturing method belongs to the technical field of the foam. The invention adopts the manufacturing method that the reclaimed materials of the foam crumbled into fine particles or power are added in the raw material used for manufacturing the foam and stirred to ensure that the reclaimed materials of the foam are evenly interfused with the raw material, then are poured into the die together,finally, the the new foam is molded integrally, and the weight ratio of the reclaimed materials of the foam is 2.5percent to 20 percent. The manufacturing method has the advantages that not only the remaining material and the waste material of the foam can be appropriately reclaimed, but also the manufacturing cost can be reduced, thus the environment protecting and reutilizing effects can be achieved, compared with the original foam, whether the product appearance, the product quality or the operational effect, the environmental protective foam produced through the manufacturing method and the original foam, are almost all identical, the manufacturing method really has a very good industrial utilizing value, and the practicability of the environmental protective foam can not be compared to the practicability of the products manufactured through the conventional manufacturing method; the technology of the manufacturing method provided by the invention is simple, and the operation is convenient.

Description

Technical field: [0001] The invention relates to the technical field of foam, in particular to an environmentally friendly foam manufacturing method, in particular to a foam manufacturing method which has environmental protection effect and can recycle foam waste. Background technique: [0002] Foam is a high-quality material with shock-absorbing and sound-absorbing effects. It is used in a wide range of industries, including furniture, building materials, shoe materials, sports equipment, automotive supplies, etc. All industries use foam products. Due to the scope of use of foam It is very wide, whether it is the residual material produced in the process of manufacturing the finished product or the waste produced after the use of the finished product, the amount is quite large, and a large amount of waste foam cannot be used. In addition to wasting resources, it is currently disposed of by incineration or landfill. , will also cause serious environmental pollution problems....

[0002] Foam is a high-quality material with shock-absorbing and sound-absorbing effects. It is used in a wide range of industries, including furniture, building materials, shoe materials, sports equipment, automotive supplies, etc. All industries use foam products. Due to the scope of use of foam It is very wide, whether it is the residual material produced in the process of manufacturing the finished product or the waste produced after the use of the finished product, the amount is quite large, and a large amount of waste foam cannot be used. In addition to wasting resources, it is currently disposed of by incineration or landfill. , will also cause serious environmental pollution problems

[0003] In order to solve the above foam waste recycling problem, in addition to recycling foam waste or waste, and crushing them into irregular blocks as fillings for some products (such as: pillows, dolls, etc.), some businesses also recycle the recycled foam After the cotton residue and waste are crushed, they are directly added to the raw materials for making foam, and a large amount of foam waste is wrapped in the newly formed foam product by means of polymerization and foaming reaction. The recycled foam residue and waste usually account for the weight ratio of 80 to 90%, so that the quality of the products obtained is poor; some companies also use the recycled foam residues and wastes after crushing, and then use rubber mixing to form a large number of block-shaped recycled foam materials. Foam body, although the above-mentioned conventional method can reduce the waste of surplus material or waste material, but because the foam body formed by this method is whether it is new material coated recycled material or recycled material is used to form a block, its product has poor quality in terms of color, luster, The quality and fire resistance are very different from the original foam. Even if the recycled foam of the same color is used to form a foam body, its appearance is still obviously composed of many block foams rather than an overall structure. In addition to the serious lack of aesthetics, the structural quality of the foam body formed by the covering or grouping is also incomparable with the integrated structure of the original foam, so its application range is extremely limited, and its use value for the industry is not high. Effectively solve environmental protection problems, and cannot really achieve the value of recycling
