Description
Technical field
The present invention relates to food packaging applications, specifically, are related to a kind of acrylic emulsion for packaging for foodstuff outer box
Binding agent.
Background technology
At present, many food package boxes include the material of direct and food contact, and major part will use binding agent.It is viscous
Mixture is a kind of auxiliary material that numerous materials can be bonded together.The species of adhesive is a lot, and wrapping material is more,
Such as adhesive material just includes solvent-borne type, half oiliness, water solublity, emulsion-type etc..And want the base material of bonding to include paper, paper
Plate, plastic material (OPP, PE, PP, PET, BOPP, PS), timber, aluminium foil etc..Those skilled in the art are by being glued from different
Mixture carrys out the different base material of bonding, so as to realize different materials being formed the purpose of an entirety.
What adhesives industries were advanced by leaps and bounds develops into society there is provided many virgin rubber kinds, while having used in production process
Toxogen material, such as formaldehyde, toxic solvent, firming agent and other auxiliary agents etc., also bring severe contamination to environment.At present, although glue
The total development trend of stick is non-organic solvent, but solvent-based adhesive is due to its excellent technique and adhesive property, especially
That the performance of non-organic solvent adhesive can't be fully achieved solvent type level at present, solvent-based adhesive still compared with
Exist in long-time.With China's entry into the WTO, and the raising of Environmental Protection in China consciousness, the technical barrier general of the aspect such as environmental protection
Highlight.Composite membrane producer and adhesive manufacturer should make joint efforts, and improve the technical merit of joint product.
In today that environmental consciousness and health perception are increasingly improved, society no longer focuses simply on the function of adhesive and answers
With the requirement to the environmental issue of adhesive is further strict, and development meets " environmental protection, health, safety " three big environment-friendly type for requiring
Green adhesive is imperative.To adapt to the needs of society and environmental protection, the kind of adhesive is especially food packaging gluing
Agent should accelerate to update, and develop towards Water-borne modification, solidification, solvent free, low toxicity direction.China Adhesive Industry association declares
Claim, environment-friendly type, energy-saving adhesive will be given priority in the five-year China, while also research and development high-tech will contain energetically
Amount, high added value, high performance adhesive new product.
Water-base emulsion adhesive is the inexorable trend of adhesive development, compared with solvent-based adhesive, is released with solvent-free
Put, environmental friendliness, it is nontoxic, non-combustible, using safety, low cost and other advantages.
With the sustainable development and the continuous improvement of people's living standard of China's economic, demand to adhesive products and
Selecting will be increasingly stricter and harsh, and those performances are good, quality is high, the product of environment-friendly type will be favored by people.
