Abstract
The utility model relates to a bright face synthetic leather of cured hydronasty, including the base cloth layer, through the coating formed at surperficial this layer shellfish of base cloth, on pasting this layer disposed on shellfish the PU overlay coating and set up in the surperficial bright surface course of cured hydronasty of PU overlay coating through the abhiseca. This bright face synthetic leather of cured hydronasty can not only strengthen the characteristic of waterborne product, and enables the genuine leather gloss that the product surface has the high bright fog contrast of nature, and surface pattern has more the pluralism simultaneously.
Description
Technical field
The utility model belongs to synthetic leather field, particularly the cured hydronasty of one bright synthetic leather.
Background technology
Current China synthetic leather is produced main based on solvent borne polyurethane (PU), Synthetic Leather belongs to a class of polyurethane elastomer, have that gloss nature, kishke feel are strong, mechanical performance and the feature such as patience is excellent, be widely used in the industries such as clothes, shoemaking, case and bag, furniture.The main technique that PU synthetic leather is produced has wet method and dry process, and dry process is with an organic solvent measured and reached 70%, causes severe contamination to environment.Wet processing is the new method grown up after dry method, use polyurethane replace solvents type polyurethane is applied in synthetic leather, feature is to adopt membrane formation process in water to obtain having the multilayer structure making of continuous poriferous layer, owing to containing a large amount of hydrophilic radical and microcellular structure in epithelium, therefore ventilative, water vapour permeability and the sense of touch the same with corium is had, sanitation performance is better, is green truly, environment-friendly products.Successfully have developed water-based bass product abroad, but China relatively lags behind for the application study of aqueous polyurethane on synthetic leather.
At present, water-based PU product processes only has traditional water-based fabric to coat in release liners, or coating roller is directly coated on water-based bass, change less, if do in cladding on the surface, technology difficulty is very high, if material allocation and temperature control bad in production, easily produces bad effect and feel.Therefore water-based PU product feels like doing out the surface effect tool with corium gloss acquires a certain degree of difficulty, and at present technique to do product more single.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of cured hydronasty bright synthetic leather, and cladding surface can be made to have the corium gloss of the highlighted mist contrast of nature.
For solving the problem, the utility model provides a kind of cured hydronasty bright synthetic leather, it comprise base cloth layer, through coat binding scrim surfaces bass layer, be sticked the PU overlay coating on bass layer and be arranged at the bright surface layer of cured hydronasty on PU overlay coating surface through abhiseca.
Preferably, described bass layer is connected by adhesive phase with PU overlay coating.
Preferably, the bright surface layer of described cured hydronasty is the cured sense leather mixture of wax sense leather agent and auxiliary agent composition.
Preferably, described auxiliary agent is one or more in polyacrylate, polyurethane.
Preferably, described PU overlay coating surface has embossing pattern, to improve the attractive in appearance of product, makes product have more diversification.
Preferably, described bass layer is larger than the thickness of PU overlay coating.
Ji Bu is mainly used as synthetic leather base material, and single coating bass base cloth used is mainly based on flat fabric, one side nylon loop.
The preparation of bass is usually as follows: by adding DMF solvent and other filler in polyurethane resin, auxiliary agent makes mixed liquor, after vacuum machine deaeration, flood or be coated on Ji Bushang, then water replacement solvent (being generally DMF) is put into, polyurethane resin solidifies gradually, thus form microvoid polyurethane grain layer, then by roll-in, drying and shaping, cooling, obtain bass.
When preparing this cured hydronasty bright synthetic leather, first carry out putting cloth through traditional process route, preimpregnation, roll compacting plated, be coated with, solidify, wash, press dry, preheating pressing, drying and shaping, cooling, namely on base cloth, form bass layer; The PU overlay coating then surface with embossing pattern adheres to bass layer by adhesive phase; After oxidant layer solidification to be bonded, bright for a cured hydronasty finishing agent is processed PU overlay coating by abhiseca processing mode, therefore cured hydronasty bright finishing agent can not flow to the cunette of PU overlay coating, but the particle being attached to PU overlay coating surface forms the bright surface layer of cured hydronasty, thus the particle on PU overlay coating surface is made to have corium brightness; After rubbing line, product has the corium gloss of the highlighted mist contrast of nature; Packaging can be batched after cooling.
The beneficial effects of the utility model:
Technical problem to be solved in the utility model is to provide a kind of cured hydronasty bright synthetic leather, and this product can not only strengthen the characteristic of aqueous product, and product surface can be made to have the corium gloss of the highlighted mist contrast of nature, and surface detail has more diversification simultaneously.

Wherein, 1, base cloth layer; 2, wet method bass layer; 3, PU overlay coating; 4, the bright surface layer of cured hydronasty; 5, adhesive phase.
Detailed description of the invention:
Embodiment: as shown in Figure 1-2, the utility model provides the specific embodiment of a kind of cured hydronasty bright synthetic leather.Cured hydronasty in this embodiment bright synthetic leather, it comprises base cloth layer 1, be formed at the bass layer 2 on base cloth layer 1 surface through coating, be sticked the PU overlay coating 3 on bass layer 2 and be arranged at the bright surface layer 4 of cured hydronasty on PU overlay coating 3 surface through abhiseca.Wherein, bass layer 2 is connected by adhesive phase 5 with PU overlay coating 3; The bright surface layer of cured hydronasty is the cured sense leather mixture of wax sense leather agent and auxiliary agent composition; Auxiliary agent is one or more in polyacrylate, polyurethane; PU overlay coating 3 surface has embossing pattern; Bass layer 2 is larger than the thickness of PU overlay coating 3.
When preparing this cured hydronasty bright synthetic leather, first carry out putting cloth through traditional process route, preimpregnation, roll compacting plated, be coated with, solidify, wash, press dry, preheating pressing, drying and shaping, cooling, namely on base cloth layer 1, form bass layer 2; The PU overlay coating 3 then surface with embossing pattern adheres to bass layer 2 by adhesive phase 5; After oxidant layer 5 to be bonded is solidified, bright for a cured hydronasty finishing agent is processed PU overlay coating by abhiseca processing mode, therefore cured hydronasty bright finishing agent can not flow to the cunette of PU overlay coating, but the particle being attached to PU overlay coating surface forms the bright surface layer 4 of cured hydronasty, thus the particle on PU overlay coating surface is made to have corium brightness; After rubbing line, product has the corium gloss of the highlighted mist contrast of nature; Packaging can be batched after cooling.
The above is preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
