Abstract
A sitting board for flush toilet is made up of polyurethane material by injection mouldling. Said polyurethane is prepared from the component A consisting of polyether, chain extending agent, stabilizer, catalyst and foaming agent and the compoent B which is isocyanate through reaction. Its advantages are no collision noise, and high toughness and tearing strength.
Description
Background technology
The present invention relates to the sanitary equipment seat cushion, relate in particular to a kind of closet seat-cushion and preparation method thereof.
Background technology
Common closet seat-cushion generally has two kinds of materials to make now, and a kind of is timber, and its advantage is that the human body sense of touch is not ice-cold, but yielding, and water resistance is bad; Another kind is a bakelite, and advantage is not yielding, good waterproof performance, but the human body sense of touch relatively ices, and the human body sensory comfort level is relatively poor.It is harder that these two kinds of materials also have a common shortcoming, and comfort level is relatively poor.Remove this, also have seat cushion in the market, but it costs an arm and a leg use inconvenience with electricity heating; The somebody overcoming ice-cold sense and to increase pliability, but uses loaded down with trivial details and not easy to clean with the cloth condom on cushion.
Summary of the invention
The object of the present invention is to provide a kind of not yielding, waterproof, softness, human body sensory comfort level closet seat-cushion preferably.
Another object of the present invention is to provide a kind of preparation method of closet seat-cushion.
A kind of closet seat-cushion of the present invention, this closet seat-cushion inject mould by polyurethane material and make, and polyurethane material is by A material and B material hybrid reaction gained, and wherein the A material package is drawn together basic polyethers, chain extender, stabilizing agent, catalyst and blowing agent; The B material is an isocyanates; The weight ratio of A material and B material is 100: 30～50; Described basic polyethers is F342, and chain extender is an ethylene glycol, and stabilizing agent is DC193, and catalyst is DABCO EG and DABCO 1027, and blowing agent is 141b; Contain in the A material in weight portion: 80～100 parts of basic polyethers, 2～8 parts of chain extenders, 1～3 part of stabilizing agent, 2～5 parts of catalyst, 10～20 parts of blowing agents;
The present invention also provides a kind of preparation method of closet seat-cushion, the cleaning, heating and the spray remover that comprise mould, the configuration of A material and B material, respectively A material and the B material that configures joined in the casting machine, in proportion A material and B material are injected mould simultaneously then, make A material and B material reaction foaming, heat-insulation pressure keeping makes its curing again, and the demoulding is through cleaning deburring promptly then; Mold heated to 45 ℃～55 ℃ wherein; The temperature of A material and B material is controlled at 20 ℃～25 ℃ before the reaction; On described closet seat-cushion, scribble film.
Closet seat-cushion of the present invention has adopted polyurethane material to make, and better with human body applying degree, sense of touch is warm, soft, and pliability is better, the tearing strength height, and also closet seat-cushion does not have strike note when digging and putting down.
The specific embodiment
Embodiment: in the present embodiment, the preparation closet seat-cushion, it at first is the configuration of A material and B material, wherein the A material package is drawn together basic polyethers F342 90kg, ethylene glycol 5kg, stabilizing agent DC193 1.5kg, catalyst DABCOEG 2.5kg, catalyst DABCO 1027 1.0kg, blowing agent 141b 15kg, the B material is isocyanates, A material and B material with said components mixes separately in proportion, join respectively then in 2 casting machines, wherein the temperature of A material remains on 20 ℃, and the temperature of B material remains on 25 ℃; Mould with well found closet seat-cushion cleans up again, is heated to 50 ℃, and release agent spraying in the above; Then A material and B material are injected mould simultaneously in 100: 42 ratios, A material and B material are reacted foam, and then heat-insulation pressure keeping makes its curing, the demoulding again after curing is finished, cleaning, deburring are promptly.
Can also on the closet seat-cushion that the foregoing description obtains, coat plastic sheeting, can also on the closet seat-cushion that obtains, spray various paint.
