Abstract
The invention discloses a DVD high-density PU plate special for automobile interior decoration. The invention is characterized in that the DVD high-density PU plate is prepared by uniformly mixing the following raw materials of: by weight, 80-60 parts of a mixture of 2-5 polyether glycol or 2-3 polyether glycol and 1-2 polyester polyol, 10-20 parts of o-phthalic anhydride and adipic acid mixed polyester polyol, 10-20 parts of high functionality polyether polyol, 1-2 parts of 1-2 rigid foamed silicone oil, 0.1-0.5 part of 2-3 amine catalysts, 5-12 parts of a foaming agent, 1.0-2.0 parts of a foam stabilizer and 0.3-0.6 part of an open cell agent and performing a reaction with 120-160 parts of crude MDI (isocyanate). The DVD high-density PU plate has strong rigidity, will not be deformed when used and requires low cost.
Description
Technical field:
The present invention relates to automotive trim and use the polyurethane foam production technical field, is that a kind of automotive trim is with DVD high-density PU plate specifically.
Background technology:
On the present automobile market, medium-to-high grade car inner decorative ceiling is installed all need increase roof sound insulation stiffening plate, is called for short the DVD plate; At first mostly be the fiber board structure, but its soundproof effect is poor, when fiber board bears higher temperature; Deform easily, form phenomenons such as uneven; Employing polyurethane foamed material (being called for short the PU plate) is also arranged now; Be skeleton promptly with the hard polyurethane foam plate; Then at the upper and lower two-layer monocomponent polyurethane sizing agent that applies respectively; And evenly spray suitable moisture; And covering upper and lower two-layer kraft paper once more, the mode through heating makes the monocomponent polyurethane sizing agent react, and imposes certain pressure and make it become automobile to use the DVD plate; But the prescription of existing polyurethane foamed material generally adopts the mixture of polyether glycol or polyether glycol and polyester polyol, the silicone oil that hard bubbles, amines catalyst, whipping agent and thick MDI, and the DVD plate that the above-mentioned raw materials proportional mixing is processed is yielding and rigidity is not enough and cost is high.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and the special-purpose DVD high-density of a kind of automotive trim PU is provided plate, solve mainly that existing automobile DVD plate is yielding, rigidity is not enough and problem such as cost height.
In order to achieve the above object; The present invention is achieved in that the special-purpose DVD high-density of a kind of automotive trim PU plate; Its special character is that it is processed by the following weight proportion raw material: mixture 80-60 part of 2-5 kind polyether glycol or 2-3 kind polyether glycol and 1-2 kind polyester polyol, phthalic anhydride and hexanodioic acid mixed polyester polyvalent alcohol 10-20 part, high functionality polyether glycol 10-20 part, 1-2 kind hard bubble silicone oil 1-2 part, 2-3 kind amines catalyst 0.1-0.5 part, whipping agent 5-12 part, foam stabilizer 1.0-2.0 part, pore-creating agent 0.3-0.6 part, thick MDI 120-160 part.
The special-purpose DVD high-density of a kind of automotive trim of the present invention PU plate, its described polyether glycol, polyester polyol are two kinds and two or more mixing among polyethers 1000, polyethers 450, polyethers 330N, polyethers 700, polyethers 3050, polyethers TED2817, polyethers 260, polyester 3152, polyester 350, the polyester DF400; The described silicone oil that hard bubbles is one or both combinations among AK-8805, AK-158, AK-8835, L580, the L-6860; Described amines catalyst is the combination of two or three among A-33, AS-33, DMEA, C6608, HP15, the HP301; Described whipping agent is one or both mixing among water, HCFC-141b, the HFC-245fa; Described thick MDI is a kind of among PM-200,44V20, M20S, the MR-200; Described foam stabilizer is the polyether modified siloxane foam stabilizer; Described pore-creating agent is an organosilicon series; Described high functionality polyether glycol is to be initiator with sucrose, the functionality 6-7 of synthesizing polyether.
The special-purpose DVD high-density of a kind of automotive trim of the present invention PU plate is on the basis of existing polyurethane foamed material; In its proportioning raw materials, adding foam stabilizer makes foam aperture evenly, in order; The adding pore-creating agent makes the PU cystose possess half-open hole and does not have powder, adds phthalic anhydride and hexanodioic acid mixed polyester polyvalent alcohol, can effectively improve tensile strength; Add the high functionality polyether glycol, make elongation at break and compressive strength that qualitative leap arranged.
The special-purpose DVD high-density of a kind of automotive trim of the present invention PU plate is reacted with thick MDI by other raw material in its proportioning, and foaming becomes urethane bulla piece, and the polyurethane foam piece that plasticizing is good is cut edge, cut into slices, and makes the special-purpose DVD high-density of automotive trim PU plate; The special-purpose DVD high-density of the automotive trim of processing PU plate density is 40～50Kg/m3.
Compared with present technology the special-purpose DVD high-density of a kind of automotive trim of the present invention PU plate has outstanding substantive distinguishing features and marked improvement, and rigidity is strong, and is indeformable in the use, and cost is low.
