Abstract
The invention relates to an environment protecting water proof aeration paper and the manufacture method. It is made up from fiber slurry and ethyl acrylic ester copolymer containing perfluoroalkyl group water-proofing agent, and the weight ratio is 1000:3-1000:12. The process includes the following steps: mixing slurry, pulping, mixing material, copying, coating and rewing. It is a fully environment protecting natural fiber water proof aeration paper and has a widely application range.
Description
technical field [0001] The invention relates to an all-environmental protection pure natural fiber waterproof air-permeable paper and a preparation method thereof, in particular to an environment-friendly waterproof air-permeable paper used in disposable products and disposable packaging instead of plastics and a preparation method thereof. Background technique [0002] The waterproof materials currently used in disposable products and disposable packaging are plastics or composite materials of paper and plastics. As waterproof materials, there are still the following disadvantages: waterproof but airtight; cannot be degraded in the natural environment, and incineration produces toxic gases , causing environmental pollution and damage to the environment. At present, the market is in urgent need of an environmentally friendly waterproof and breathable paper that is waterproof, breathable and degradable in the natural environment without damaging the environment.
