Description
Technical field
The present invention relates to a kind of processing technology of mat, particularly a kind of processing technology of hydrogel pad.
Background technology
Hydrogel is the new functional macromolecule material that a class has three-dimensional net structure, can be by one or more monomers, through chemical initiator initiated polymerization and crosslinked and get, hydrogel can be in water swelling and keep certain moisture and don't water-soluble, its water content is high, swelling is fast, soft, have toughness as the rubber and a good biocompatibility, stimulate to external world, have good response such as temperature, electric field etc., so hydrogel is widely used in every field.The sheet-like hydrous gel pad that parcel is arranged as can make the outside with hydrogel, this hydrogel is lined with good heatstroke prevention air permeable effect and enjoys the people parent to look at, its principle is to utilize a large amount of absorber exterior heat of the high specific heat capacity of moisture amount in the hydrogel, the three-dimensional netted molecular structure quick heat radiating of recycling hydrophilic gel, thus realize that Physical temperature-lowering reaches nice and cool effect.For example publication number is: CN101305877, denomination of invention are the Chinese invention patent application of " gel mat and production method thereof ", disclose a kind of gel mat and production method thereof, comprised the following steps: successively to get the raw materials ready, bag, can monomer solution, be heating and curing, check and pack.The production method of this gel mat exists certain defective and deficiency, in the step that is heating and curing, needs rely on two-layer or Multi-layer warming plate physics is heated, namely the sack that monomer solution is housed is placed in the middle of two heating plates, make its internal solution reach polymerization temperature, realize the formation of water-in-bag gel, and use the equipment of air pressure or the extruding of hydraulic energy free lifting, to the pressurization of the gel mat in two-layer or Multi-layer warming plate typing.In heating process, heating plate is heated and can be produced a large amount of energy consumptions, and make the monomer solution of normal temperature reach polymerization temperature with heating plate and need a period of time, production efficiency is lower, therefore the process that gel mat is produced in the physical heating that this usefulness is two-layer or the Multi-layer warming plate carries out and pressurization, complicated operation, cost is high, is not suitable for new industrialization production.
Summary of the invention
The objective of the invention is for the deficiencies in the prior art, provide a kind of simple to operate, production efficiency is high, be applicable to the processing technology of the hydrogel pad of suitability for industrialized production.
The objective of the invention is to be realized by following technical scheme, may further comprise the steps successively:
1) bag: cut out the appearance and size of suitable hydrogel pad and the skin-material of material requirements, described skin-material refers to that internal layer is that plastics, skin are the composite of weaving face fabric, use high frequency or electric heating mould, make the fusion of being heated of skin-material inner plastic, make leave perfusing hole around the sack of sealing;
2) preparation hydrogel raw material:
First monomer, pure water, crosslinking agent, the soft conditioning agent of colloid, initator are mixed and made into solution A,
Again pure water, polymerized at normal temperature are inspired agent and be mixed and made into solution B; Perhaps
First monomer, pure water, crosslinking agent, the soft conditioning agent of colloid, polymerized at normal temperature are inspired agent and are mixed and made into solution C,
Again pure water, initator are mixed into solution D; Perhaps
First high molecular polymer, pure water, defoamer are mixed and made into solution E,
Again pure water, crosslinking agent are mixed and made into solution F;
3) can: solution A and solution B are evenly mixed, perhaps
Solution C and solution D are evenly mixed, perhaps
Solution E and solution F are evenly mixed, with the quantitative liquid bottle placer filled with solution after mixing is arrived in the bag;
Add simultaneously anticorrisive agent and/or pigment and/or essence, extract the bag Air out, the welded closure filling exit;
4) solidify;
5) packing: the qualified rear packing warehouse-in of the examination and test of products;
It is characterized in that:
Described curing is that the sack that can is good is sent into the conveyer belt type shaping equipment, sack is polymerization typing during transmission in the conveyer belt type shaping equipment, initator in the bag in the mixed solution inspires agent after room temperature contacts 5-120min with polymerized at normal temperature, chemical reaction and release heat occur, solution heats up and reaches polymerization temperature in the bag, polymerization reaction take place and crosslinked generation hydrogel.
The soft conditioning agent of described monomer, pure water, crosslinking agent, colloid, initator and polymerized at normal temperature inspire the weight ratio of agent between them: monomer 5-20%, pure water 60-85%, crosslinking agent 0.1-10%, the soft conditioning agent 5-30% of colloid, initator 0.1-10%, polymerized at normal temperature inspire agent 0.1-10%; Described high molecular polymer, pure water, crosslinking agent, the defoamer weight ratio between them is: high molecular polymer 1-15%, pure water 75-90%, crosslinking agent 1-10%, defoamer 0.01-1%.
The soft conditioning agent of described monomer, pure water, crosslinking agent, colloid, initator and polymerized at normal temperature inspire the preferred weight ratio of agent between them: monomer 12-18%, pure water 60-80%, crosslinking agent 0.2-5%, the soft conditioning agent 5-20% of colloid, initator 0.2-5%, polymerized at normal temperature inspire agent 0.2-5%.
The characteristics of processing technology of the present invention are: after utilizing polymerized at normal temperature to inspire agent and initator to mix in bag, chemical reaction and release heat can occur at ambient temperature, make a bag interior mixed solution reach the formation that polymerization temperature is realized the water-in-bag gel, namely chemistry is heated and is impelled the formation of hydrogel, this step need not external heat source and additionally heats, and has reduced energy consumption; Using the conveyer belt type shaping equipment is hydrogel pad pressurization typing, the serialization of conveyer belt type shaping equipment energy, high efficiency pressurization typing, and easy and simple to handle, ability to work is large, thus it is low to reduce production costs, and enhances productivity.Crawler belt in the conveyer belt type shaping equipment can be made the crawler belt with various lines, hydrogel pad through its pressurization typing also can be with various lines, the gained hydrogel pad is practical, can customize as required the different size specification, product has good ventilative, heat dispersion, soft comfortable, balance and stability is durable in use.
