Abstract
The invention discloses a compound-enzyme soaking agent used for leather making. The compound-enzyme soaking agent comprises following components by weight: 1 part of a compound enzyme preparation, 1-5 parts of a surfactant, 2-10 parts of urea, 1-5 parts of a pH regulator and 10-50 parts of a diluent. The compound-enzyme soaking agent is capable of accelerating grease decomposition and water penetration, accelerating removal of interfibrillar substances, shortening the soaking time, largely reducing the using amount of sodium chloride and the using amount of the surfactant, and significantly reducing pollution of neutral salts in the soaking processes of leather making.
Description
Technical field
The present invention relates to leather chemicals technical field, particularly relate to a kind of process hides containing compound enzymic preparation immersion agent.
Background technology
In leather production, immersion is that first operation is also a critical process.Due to anticorrosion and preservation, there is dehydration to some extent in raw material skin.Its interfibrillar substance of raw material skin after dehydration shrinks, and collegen filament are bonded together, and this hinders the infiltration of water and chemical, thereby has influence on the quality of process hides processing.The abundant backwater of raw material skin, will be the infiltration of chemical and giving security of chemical reaction in subsequent manufacturing processes.Traditional process hides immersion process time is long, in order to accelerate immersion process, guarantees that whole skin evenly soaks, and conventionally need to add Soaking and promote immersion.The Soaking using in tradition process hides mostly is the materials such as acid, alkali, neutral salt, tensio-active agent, these Soakings exist interfibrillar substance and remove few, the defect that backwater is inhomogeneous, and the use of a large amount of acid, alkali, salt is also one of main source of the most unmanageable neutral salt pollution in leather-making waste water.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the agent of soaking of a kind of process hides prozyme, in the immersion process of process hides, not only can accelerate the decomposition of grease, the infiltration of water, accelerate removing of interfibrillar substance, shorten soaking time, and greatly reduced the consumption of sodium-chlor, tensio-active agent, reduce significantly the pollution of neutral salt.
