The invention relates to the technical field of ships, in particular to the preparation method of buoy filling materials. The method includes the following steps: feeding material A and B into feeding pump respectively, feeding material A into feeding tank, feeding material B into feeding tank to isolate raw material from humid air; injecting compressed air into feeding tank, the pressure of feeding tank A is controlled at 0.25 0.3 mpa, and that of feeding tank B is controlled at 0.15 0.2 mpa, and the quantitative pump is proportioned according to the ratio of material A and material B at 100:46; and the pressure of feeding tank A and B is controlled at 0.25 0.3 mpa. The low-pressure side of the metering pump is emptied by the lower filter, heated to 25 degrees, and the metering pump converts the low-pressure material into high-pressure material; a hole of 2CM diameter is opened every 50CM interval on the buoy, the high-pressure mixing gun head is inserted into the hole, the injection switch is opened and the cooling pump is opened at the same time; the high-pressure gun head is injected at the speed of 5.6 seconds per 3kg and cubic meter, and placed for 24 hours to solidify, and the finished product is Cheng. The product prepared by this method has a water avoidance rate of over 98%, and will not cause surface damage, leakage, fracture and aging.

一种浮筒填充材料的制备方法及带有浮筒的救援船
本专利技术涉及船舶
,尤其是一种浮筒填充材料的制备方法。
技术介绍
现有救援船的浮筒中填充的的发泡材料采用传统工艺制备,由于密度小,其压缩强度不佳,长期使用容易老化断裂;并且其PVC表层容易破损漏气,造成船艇浮力不够,影响正常使用。
技术实现思路
本专利技术的目的是解决传统工艺制备的浮力材料存在的技术缺陷,提供一种硬质浮力材料的制备方法及其用途。本专利技术解决其技术问题采用的技术方案是:一种硬质浮力材料的制备方法,包括以下步骤:第一步:将A料、B料分别注入到A料罐、B料罐中,使原料与潮湿空气隔绝,确保每种原料罐内的原料大于50公斤;所述的A料为组合聚醚多元醇,B料为异氰酸脂;第二步:将压缩空气注入到A、B料罐里,A料罐气压控制在0.25‐0.3mpa,B料罐气压控制在0.15‐0.2mpa,定量泵按照A料:B料=100:46的比例,进行配比控制;第三步:A、B料在气压的作用下经过过滤器流入计量泵的低压侧入孔,加热到22-25度,计量泵以3000转/分钟的高速运转将低压料转换成高压料,使原料整体受热均匀,温度一致;第四 ...
