Description

A kind of environmental protection is grease proofing to use paper
Technical field
The present invention relates to pulping and paper-making fields, and in particular to a kind of environmental protection is grease proofing to use paper.
Background technique
Mainstay one of of the paper as modern packaging material, have raw material sources are wide as plastics, price is opposite The advantages that cheap, and for opposite glass and metal, light portable, printability is excellent, is readily transported, therefore, daily Wide application has been obtained in life and industrial production.It is well known that packaging material is because of the property of material, the production work of product The packaging of different function, such as damp-prrof packing, mouldproof packaging, oil packing can be obtained in skill and purposes difference.In recent years, along with Economic rapid development, paper packing material are continuously increased in transportation and packing and the application in food packaging, and paper wrapper becomes dosage Maximum packaging material.Greaseproof refers to a kind of paper for resisting fat migration and absorption.Being mainly characterized by for it can Meet protection product, easy to carry, promotes sale etc. to require, reduce the infiltration of oleaginous material.In order to obtain grease proofing oil resistance effect, Film is made in the plastic package materials such as people can be formed using poly- second, polypropylene and polychlorostyrene second hoof, but these thin-film materials are in nature Boundary is difficult to degrade or degradation is extremely slow.Although they have the ability for resisting fat migration, these plastic package materials Waste difficulty recycles and causes greatly to pollute to human environment.And greaseproof is quite different, papery is degradable, and environmental protection is recyclable. Degradable high molecular material and paper products can substitute this natural environment packaging material difficult to degrade, wherein degradable high score Sub- material can be divided into 3 kinds；One is the high molecular polymers with biological engineering method polymerization preparation, it can be in natural ring The investment of production equipment for being gradually degraded into the carbohydrate of small molecule in border, hardly causing damages to environment, but need Greatly；Second is that starch is penetrated into macromolecule resin, and using the readily degradable of starch, this packaging material is in rainwater or micro- Under the action of dirt object, packaging material is set to split into tiny particle due to rotting for starch, but these tiny particles stay in In soil, many years will not be decomposed, also without really solving the problems, such as environmental pollution；The third is biodegradable plastic, this Plastics be in macromolecule resin be added can photosensitised degradation catalyst, by microorganism decomposition and plant photosynthesis, The macromolecular chain of high molecular material is broken, and is gradually degraded into small molecule compound, but also need also in the scientific research and testing stage at present It further to investigate.And paper material is then different, it is degradable, and environmental protection is recyclable, and the paper material after use is not easy to environment It pollutes, and raw material sources are extensive, it is cheap, it can be received by the majority of consumers, and be suitable for a variety of printing skills Art.But since paper fiber is per se with diameter base, and paper structure has porosity, therefore common paper wrapper does not have Oil preventing performance, it is therefore necessary to carry out anti-oil processing, can be only achieved the requirement of oil packing.Current most of producers are in production waterproof When oilproof food wrapper, it is intended to the oil-proofing agent of fluorine element lipid is added as raw material or in papermaking using plastics, However, either plastics greaseproof that fluorine element lipid is still added as raw material, is high molecular polymer, exists and be difficult to give birth to Object degradation, not environmentally, the defects of oil preventing performance is poor.
